We're forever promoting cleaning with baking soda. After all, most of us have a box or tub of baking soda in the back of a kitchen cabinet or in the pantry. If you've only ever used baking soda in home baking as a leavening agent in cookies, cakes and muffins, you might be surprised to know that it's really effective when used around the house to keep everything from mugs and ovens to carpets and curtains fresh and clean.
This humble white powder is an important alkaline that can take on the toughest of cleaning tasks and there are so many things you can clean with baking soda. It’s also one of the best eco-friendly ways to keep everything looking good as new. Here’s our pick of the top cleaning tips for things you can clean with baking soda.

There are so many things you can clean with baking soda really effectively – without the need for store-bought cleaning chemicals. Remember, too, if you have a really tough cleaning job to do, you can use baking soda when cleaning with vinegar or when cleaning with lemon juice as these pairings make a powerful combination. In the meantime, these are our top jobs for cleaning with baking soda, the pantry staple you probably already have at home.
'I keep a large tub of baking soda (I like this one from Amazon ) in my utility room,' says Lucy Searle, Homes & Gardens' Editor in Chief. 'That way, there's always some on hand to tackle a whole raft of household cleaning jobs, as well as weekend baking.'
1. Windows

If you'd rather not use strong chemicals, using baking soda to clean windows can be a more eco-friendly way to get a streak-free finish. 'Simply apply the baking soda to a damp cloth and smear over the glass; then simply remove and buff it clean,' says Megan Slack, H&G's News Writer and resident cleaning expert. 'Any stubborn marks, perhaps caused by limescale or grease, can be removed by applying the baking soda, then spraying on some white vinegar before wiping off and buffing. '
2. The oven

No-one likes using harsh chemicals with their toxic odor that doesn’t do our environment any good. Instead, simply use a homemade paste of baking soda and water brushed onto the surfaces will help you to clean an oven really effectively. Spray the paste with white vinegar and let it foam to shift really stubborn grime. Repeat spraying as needed until any baked-on food residue can be easily wiped away.
'I am a big fan of steering away from harsh chemicals in the oven so use a more natural method of baking soda and white wine vinegar,” agrees Lynsey Crombie, the self-styled Queen of Clean . 'Baking soda is really effective and makes the daunting task of oven cleaning a little easier. All you have to do to get a shining oven is spray the whole oven down, including cleaning a glass oven door, with a water bottle so that it is damp. Pour on a thick layer of baking soda, especially on the bottom, until there is about a quarter inch layer of soda paste on the bottom. If any of the baking soda is still dry, I wet it with the water bottle.'
3. Carpets and curtains

Lynsey Crombie also recommends making your own freshening spray for a carpet, curtains and fabric surfaces, 'Mix up into a spray bottle half boiling water, two teaspoons of baking soda and a capful of your favorite fabric softener. Allow to sit for half an hour so all the products mix together and then spray away. Always keep a distance of approximately 8in (20cm) when spraying and be careful around pets and children.'
Another fan of baking soda for cleaning tasks is Erin of Lemons, Lavender and Laundry . 'Many years ago I decided to start making my own cleaning products,' she says. 'At first, it was simply a way to save money. Then, it became a way to reduce toxic chemicals in our home. I never knew baking soda was such a powerful, effective cleaning agent until I started to explore all the ways it can be used... clean your oven, freshen fabrics and carpets, clean your sink. .. The list goes on.'
4. The shower

Limescale is the enemy of all showers, especially if you live in a hard water area. To get rid of that scaly build-up quickly and without fuss when you’re cleaning a bathroom, take a wet microfiber cloth and sprinkle a small amount of baking soda and a few drops of dishwasher liquid onto it.
Rub the cloth to make a soapy lather and scrub the shower screen. For the shower tray, sprinkle some baking soda straight onto the floor, adding a squirt of dishwashing liquid then rubbing with a wet brush. Rinse everything with hot water and dry with a dry cloth. Shower curtains can also be cleaned with the same cloth.
5. Mugs and china

'I drink a lot of tea and coffee while working,' says Lucy Searle, Global Editor in Chief for Homes & Gardens, 'My mugs quickly become stained and are hard to get clean in the dishwasher. One of my favorite cleaning hacks is to sprinkle a small amount of baking soda onto a scouring pad and scrub for about five minutes. It does need some elbow grease but once finished, simply pop in the dishwasher or rinse under the tap and it looks as good as new. It works for other china that's gotten stained, too.'
6. Drains

Our household drains can quickly turn stinky if they don’t get some TLC every now and then. So once a week, run some hot water down the drain – on sinks, showers and baths – then pour in about half a cup of baking soda. Let it sit there for 15 minutes or so and rinse with hot water. Het presto, any nasty smells will disappear.
7. Le Creuset

Our cookware can also benefit from baking soda. Marisa Kerkvliet of @lemon.thyme.kitchen uses it for her best Le Creuset buys, 'After a few years of use, my beloved Le Creuset was starting to show some wear with staining and discoloration both on the inside and out. This morning I discovered that simply boiling water and baking soda in the pan for 15 minutes did the trick and left the pan sparkling clean. '
You can also use this trick for pretty much any pan, apart from aluminum.
8. Laundry

Get rid of odors on dirty clothes and keep whites white at the same time by adding a cup of baking soda to your laundry every time you wash. It also helps keep bright colors bright, too.
9. Tile grout

Tiles can look dirty and grubby if the grout has those horrible black spots caused by mould and mildew. So to clean grout, mix together two parts baking soda and one part hydrogen peroxide (available at drug stores and health shops). Use an old toothbrush to apply it to the grout. Leave for 20 minutes then rinse with clean water.
10. Sinks

To keep your sink in tip-top condition when you’re cleaning a kitchen, simply sprinkle some baking soda onto half a lemon and wipe all around the sink before rinsing with water. The acid and alkaline react together to create a frothy substance that helps dissolve dirt.
11. Refrigerator

When foods start to go off in the refrigerator, it can quickly become a bit smelly inside. So keep a small bowl of baking soda in the refrigerator and this will help to neutralize any odors. As part of your refrigerator cleaning regime, change it every few weeks to keep it working efficiently.
12. Tupperware
Tupperware is so handy for storing leftovers but when you are organizing Tupperware, have a look to find those items that are starting to look a bit stained. Simply soak overnight in washing-up bowl filled with hot water and a dash of baking soda.
13. The microwave
Pop a spot of baking soda onto a damp sponge and use it to clean a microwave. Quick and easy and it helps get rid of odors, too.
14. The trash can
Cleaning with baking soda is a really good way to deodorize smelly items, too. Think: the trash can that has a lingering aroma that you just can't get rid of. The best way to tackle it is to wash out the trash can with hot water and dish soap, empty it of the dirty water then, while it is still wet, sprinkle baking soda into it. Leave for 15 minutes then rinse and allow to dry. If the smell persists, spray the trash can with vinegar then sprinkle on the baking soda. Allow to sit for a few minutes, rinse and dry.
15. The pool

Using baking soda in your pool is an effective way of increasing the alkalinity and pH level for clear water and curing black algal outbreaks on your pool's walls.
Alicia Johnson, founder of Cleaning Green LLC , says: 'The rule is 1.5 lbs of baking soda per 10,000 gallons of water will raise the ppm by 10.'
Does baking soda kill ants?
Yes, baking soda does kill ants, when mixed with vinegar. Sprinkled liberally over an ants' nest, this will help you get rid of an infestation. However, we would never advocate killing ants if you can get rid of them in more humane ways, or simply by removing what tempts them into your home or yard.
Can baking soda kill bed bugs?
Can baking soda kill bed bugs? The short answer is: no. If you have a bed bug infestation, you need a professional to help you get rid of it.
Is baking soda a good cleaning agent?
Yes, baking soda is a good cleaning agent. Baking soda acts as a cleaning agent because it is a mild alkali and can cause dirt and grease to dissolve easily in water for effective removal. Because baking soda is a pure, natural product that is also a food, it is non-toxic, unlike many other household cleaners.
What can you not clean with baking soda?
Things you should never clean with baking soda include aluminum cookware. While you can give many metal surfaces a scrub with baking soda, use caution if you’re cleaning aluminum cookware. Also, never use it for cleaning silver and gold if it’s antique, gold-plated serving pieces and marble surfaces. Also avoid cleaning marble countertops and ceramic hobs.

Cleansing the body with soda: indications, contraindications, methods of implementation.
For the full flow of metabolic processes in the body, the correct acid-base balance must be maintained. The pH level can deviate up or down due to irrational nutrition, stress, the influence of external factors, heavy physical exertion, severe pathologies, such as diabetes, prolonged fever, severe burns, metabolic diseases, diseases of the kidneys, intestines. There is a very popular opinion that baking soda helps restore balance. Let's try to figure out if this is true? nine0005
Is it possible to cleanse the body with soda?
Normal level Blood pH in the body is about 7.4. If it is shifted towards an acidic environment, then a person's metabolism slows down, the delivery of nutrients and oxygen to cells worsens, vital functions are inhibited, and immunity decreases.
Soda, when dissolved, makes the aqueous medium slightly alkaline. Such a solution neutralizes acids, alkalizing the body. By restoring the pH level, you can improve the body's ability to cleanse blood vessels, blood and lymph, and neutralize toxins. nine0005
Abuse of sodium bicarbonate is fraught with a shift in the acid-base balance towards alkalization and the occurrence of alkalosis, i.e. alkalization of the body. . In addition, the intestine gets used to the impact on its environment from the outside and gradually ceases to regulate it. Also in the body there is a special system that maintains the constancy of the internal environment - the system of homeostasis. With prolonged use of soda and alkalization, it will cause a shift in pH to the acid side using compensation mechanisms. Excess soda can also cause leaching of intestinal microflora. nine0005
Therefore, before resorting to alkalization, you need to consult a doctor to make sure that the procedure is necessary and that there are no possible health risks. This is especially true for people with kidney disease, edema, bowel disease, stomach or duodenal ulcers. .
Absolute contraindications to soda alkalization are pregnancy, lactation, low pH, hypertension, diseases of the gastrointestinal tract, oncological pathologies, and diabetes. nine0005
Attention! To independently control the process of alkalization of the body, purchase litmus papers at the pharmacy that determine the pH level of saliva or urine.
The safer way to normalize your pH is by eating the right foods. Cereals, any fruits, green vegetables, dairy products have an alkalizing property.
Cleansing of the body can be carried out in other ways. For example, using Phytotea from wild herbs No. 1 (Cleansing and drainage) - Baikal Tea Collection. Herbal collection with hay, buckthorn, Kuril tea and clover accelerates metabolic processes and helps to remove toxins from the body. nine0005
Also, the natural Cleansing phytosorbent Pure Life - Essential Sorbents is perfect for cleansing the body, the plant components of which bind accumulated harmful substances and quickly remove them in natural ways. In addition, phytosorbent normalizes metabolic processes in the body and ensures proper functioning of the gastrointestinal tract.
Methods and rules for using soda at home
You can not use soda powder in dry form, washed down with water. A solution is prepared from it. To do this, sodium bicarbonate is quenched with a small amount of boiling water. nine0005
At first, it is better to use a minimum of soda for alkalization: at the tip of a teaspoon. The maximum daily dosage is 1 tsp. The drug should be taken in the morning on an empty stomach and / or during the day one hour before or one hour after a meal.
Neumyvakin prescription
All week before and after the procedure it is necessary to adhere to a plant-based diet. Meat, smoked, fried, salty dishes are excluded from the menu. The cleaning itself is carried out for 6 days: nine0005
- 1st: drink ⅟₄ tsp 3 times. soda quenched in 200 ml of boiling water;
- 2nd: drink ⅟₂ tsp. powder diluted with 200 ml of boiling water, in the same mode;
- 4th, 5th and 6th: dilute in the morning 1 tbsp. l. powder in 1.5 liters of hot water and drink throughout the day, alternating with vegetable broths and apple juice;
- second half of the 6th day: mix 200 ml of lemon juice with 200 ml of olive oil and drink in small sips every 15 minutes, and before going to bed make an enema. nine0056
Attention! During cleaning, you need to monitor your well-being. If you experience discomfort of any kind, whether it be heartburn or increased gas formation, you should stop taking it and consult a doctor.
Ogulov's prescription
First, they take a soda solution, gradually increasing the dosage from ⅟₅ to ⅟₂ tsp. powder in 200 ml of water. After that, using Esmarch's mug, an enema is made from 30 g of salt and 2 liters of water. Then drink a cleansing solution of 1 tbsp. l. soda and 800 ml of boiling water and complete the cleaning with an enema of 2 liters of water, 2 tbsp. l. salt and 5 ml lemon juice. nine0017
Full course - 10 procedures in 1 day.
Preventive
For prevention, you can drink in the morning, on an empty stomach, for 1-2 weeks a warm soda solution, gradually increasing the dosage. The maximum amount of powder must not exceed 0.5 tsp. 200 ml of liquid per day.
Cleansing the body requires a systematic approach, and it is precisely provided by the Origins of Purity, the legendary Siberian Wellness complex, consisting of three complementary formulas that ensure the operation of the three main mechanisms for cleansing the internal environment of the body: intercellular cleansing, intracellular cleansing and antioxidant protection. nine0005
You can also cleanse the body from the outside, taking soda baths 1-2 times a week: 100 g of powder and 50 g of sea salt for a full bath. This procedure will help cleanse the lymphatic system, improve metabolic processes, accelerate weight loss, improve blood circulation and skin condition.

It is essential to know the hardness of the water used. Many aspects of our life depend on the hardness index of drinking water: how much washing powder to use, whether measures are needed to soften hard water, how long aquarium fish will live in water, whether it is necessary to introduce polyphosphates in reverse osmosis, etc.
There are many ways to determine the hardness:
- by the amount of detergent foam formed;
- by district; nine0056
- by the amount of scale on the heating elements;
- for taste properties of water;
- with reagents and special instruments
What is hardness?
The water contains the main cations: calcium, magnesium, manganese, iron, strontium. The last three cations have little effect on water hardness. There are also trivalent aluminum and iron cations, which at a certain pH form a limestone deposit.
Hardness can be of different types:
- total hardness – total content of magnesium and calcium ions;
- carbonate hardness - the content of bicarbonates and carbonates at a pH greater than 8.3. They are easy to remove through boiling: during heating, they decompose into carbonic acid and sediment;
- Non-carbonate hardness Calcium and magnesium salts of strong acids; cannot be removed by boiling.
There are several units of water hardness: mol/m 3 , mg-eq/l, dH, d⁰, f⁰, ppm CaCO 3 .
Hard water
Why is water hard? Alkaline earth metal ions are found in all mineralized waters. They are taken from deposits of dolomites, gypsum and limestone. Water sources can have hardness in various ranges. There are several stiffness systems. Abroad, they approach her more “toughly”. For example, in our country water is considered soft with a hardness of 0-4 mg-eq/l, and in the USA - 0-1.5 mg-eq/l; very hard water in Russia - over 12 mg-eq/l, and in the USA - over 6 mg-eq/l. nine0005
The hardness of low-mineralized waters is 80% due to calcium ions. With an increase in mineralization, the proportion of calcium ions sharply decreases, while that of magnesium ions increases.
Most often, surface water is less hard than groundwater. The stiffness also depends on the season: during the snowmelt, it decreases.
The hardness of drinking water changes its taste. The sensitivity threshold for the calcium ion is from 2 to 6 meq/l, depending on the anions. The water becomes bitter and badly affects the digestion process. WHO does not give any recommendations on water hardness, as there is no exact evidence of its effect on the human body. nine0005
Hardness limitation required for heaters. For example, in boilers - up to 0.1 mg-eq / l. Soft water has low alkalinity and corrodes plumbing. Utilities use special treatments to find a compromise between plaque and corrosion.
Hard water softening
There are three groups of water softening methods:
- physical;
- chemical;
- psychic. nine0056
Chemical methods of water softening
Ion exchange
Chemical methods are based on ion exchange. The filter mass is an ion exchange resin. It is a long molecule that is collected in yellow balls. Small processes with sodium ions protrude from the balls.
During filtration, water permeates the entire resin, and its salts take the place of sodium. The sodium itself is carried away by the water. Due to the difference in ion charges, 2 times more salts are washed out than are deposited. Over time, the salts are all replaced and the resin stops working. Each resin has its own period of work. nine0005
Ion exchange resin can be in cartridges or poured into a long column. Cartridges are small and are only used to reduce the hardness of drinking water. Ideal for water softening at home. An ion exchange column is used to soften water in an apartment or small production. In addition to the high cost, the column must be periodically loaded with a regenerated filter mass.
If there are no sodium ions left in the cartridge resin, then it is simply replaced with a new one, and the old one is thrown away. When using an ion exchange column, the resin is restored in a special brine tank. To do this, dissolve the tableting salt. The saline solution regenerates the resin's ability to exchange ions. nine0005
The downside is the additional ability of water to remove iron. It clogs the resin and makes it completely unusable. It is time to do a water analysis!
Use of other chemicals
There are a number of less popular but effective ways to soften water:
- soda ash or lime;
- polyphosphates;
- anti-scalants - compounds against the formation of scale.
Softening with lime and soda
Water softening with soda
The method of softening water using lime is called liming. Use slaked lime. The content of carbonates is reduced.
A mixture of soda and lime is most effective. For clarity, water softening at home, you can add soda ash to the washing water. Take 1-2 teaspoons per bucket. Stir well and wait for the precipitation. A similar method was used by women in ancient Greece, using stove ash. nine0005
Water after lime and soda is not suitable for food purposes!
Softening with polyphosphates
Polyphosphates are able to bind hardness salts. They are large white crystals. Water passes through the filter and dissolves polyphosphates, binding salts.
The disadvantage is the danger of polyphosphates for living organisms, including humans. They are a fertilizer: after entering the pond, there is an active growth of algae. nine0005
Polyphosphates are also unsuitable for softening drinking water!
Physical method of water softening
Water softening filter
Physical methods combat the consequences of high hardness - scale. This is a non-reagent water treatment. When using it, there is no decrease in the concentration of salt, but simply prevents harm to pipes and heating elements. Water becomes soft or, for better understanding, softened.
The following physical methods are distinguished:
- use of a magnetic field;
- using an electric field;
- sonication;
- thermal method;
- use of low-point current pulses.
Magnetic field
Chemical-free water softening with a magnetic field has many nuances. Efficiency is achieved only if certain rules are observed:
- a certain water flow rate;
- matched field strength; nine0056
- determined ionic and molecular composition of water;
- inlet and outlet water temperature;
- processing time;
- atmospheric pressure;
- water pressure, etc.
Changing any parameter requires a complete reconfiguration of the entire system. The reaction must be immediate. Despite the complexity of parameter control, magnetic water softening is used in boiler rooms.
But to soften water at home using a magnetic field is almost impossible. When you want to buy a magnet for the pipeline, think about how you choose and provide the necessary parameters. nine0005
Use of ultrasound
Ultrasound causes cavitation - the formation of gas bubbles. Increases the likelihood of a meeting of magnesium and calcium ions. Crystallization centers appear not on the surface of the pipes, but in the water column.
When softening hot water with ultrasound, the crystals do not reach the size required for deposition - scale does not form on the heat exchange surfaces.
Additionally, high-frequency vibrations occur that prevent the formation of plaque: they repel crystals from the surface. nine0005
Bending vibrations are detrimental to the formed scale layer. It begins to break off in pieces that can clog the channels. Surfaces must be descaled before using ultrasound.
Electromagnetic impulses
Chemical-free electromagnetic impulse water softeners are changing the way salts crystallize. Dynamic electrical impulses with different characteristics are created. They go along the wire-winding on the pipe. Crystals take the form of long shelves, which are difficult to gain a foothold on the heat exchange surface. nine0005
During the treatment, carbon dioxide is released, which fights against existing lime deposits and forms a protective film on metal surfaces.
Thermal softening
Someone hears about this method for the first time. But in fact, everyone has been using it since childhood. This is our usual way of boiling water.
Everyone noticed that after boiling water, a precipitate of hardness salts forms. Coffee or tea is made from softer water than tap water.
How much to boil? It's simple: with an increase in temperature and its effect, hardness salts are less soluble and precipitate more. During heating, carbon dioxide is released. The faster it evaporates, the more limestone deposits form. A tightly closed lid prevents carbon dioxide from escaping, and liquid quickly evaporates in an open container.
When using heat softener, leave the lid slightly open in the container.
