Bicarbonate of soda cleaning works best when you choose dry powder, paste or a diluted solution for a compatible material, then remove every trace of residue.
Cleaning is my second favourite use for baking soda (after, you know, baking). Baking soda (also known as bicarbonate of soda) is an extremely versatile and natural cleaner. You can use it in a ton of ways around your home.
Thanks to its abrasive nature, it can help you scrub away dirt and grime. It’s also great against oils and other organic stains. As if that weren’t enough, it’s also a natural deodoriser. But let’s dig deeper into how you can use baking soda for cleaning.
| Form | Where it may fit | Main limit |
|---|---|---|
| Dry powder | A small, contained odour-absorption or light scouring task where every grain can be removed. | Loose powder can remain in fibres, seams, motors and ventilation paths. |
| Water paste | A local greasy or sticky deposit on a compatible hard surface that tolerates mild abrasion. | A thick or dried paste can scratch, leave a white film or trap moisture at joins. |
| Diluted solution | A light wipe on a washable surface where less abrasion is preferable. | It still needs full removal and can leave alkaline residue as the water evaporates. |
| Neither | Unknown finishes, natural stone, aluminium, delicate fibres, damaged coatings, valuable objects and appliance internals. | Use the maker’s approved product or specialist route instead of experimenting. |

Bicarbonate is mildly alkaline and only slightly soluble in water. Its grains can provide abrasion before dissolving, which explains both the cleaning value and the risk to gloss, coatings and delicate surfaces. Odour absorption may reduce some smells, but a reduced smell does not prove that the source, contamination or moisture problem has gone.
Mould is a nasty problem to have. Unfortunately, it’s exceptionally common in many London homes. The good news is that baking soda offers a simple and effective solution so you won’t have to use harsh chemicals to deal with it.
Wait, baking soda is a fungicide? Yup. On top of being a natural and safe alternative to chemical mould removers, baking soda has mild abrasive properties that can help scrub away mould and mildew. And, as I’ve already mentioned, it’s a natural deodoriser which can help get rid of musty smells.
To use baking soda for mould removal, start by mixing equal parts soda and water to create a paste. Then, apply the paste to the mouldy area and scrub gently with a scrub brush or sponge. I’d put on gloves before this step if you’re squeamish. Finally, rinse the area thoroughly with dry it completely.
But removing the mould is just half the battle. To prevent it from returning, you can also use baking soda as a natural mould inhibitor. Simply sprinkle a thin layer of baking soda over the affected area and let it sit for a few hours before vacuuming it up.
By using baking soda, you can easily and safely deal with mould in your home, helping to keep it clean and healthy. However, if you’re having frequent mould issues, you may want to look into other solutions.
Mould boundary: bicarbonate may help remove light surface residue from a compatible washable material, but it should not be treated as a proven fungicide or a substitute for correcting condensation, leaks or damp. Do not spread dry powder over a mouldy area, disturb extensive growth or scrub a porous material that cannot be rinsed and dried fully. Recurring mould, a strong damp smell, damaged plaster or growth covering a substantial area needs moisture diagnosis and appropriate specialist advice.
No matter how careful you are, spills are inevitable so you have to be prepared. To clean tea and coffee stains using baking soda, you can follow these steps:
Alternatively, you can also sprinkle baking soda directly on the stain and then scrub it with a wet sponge or cloth. It’s nothing complicated.
Note: Test this solution on an inconspicuous area to make sure it won’t damage the surface or fabric.
For tough stains, you may need to repeat the process a few times to completely remove the stain. If this doesn’t work, there are more options for coffee or tea stain removal.
Some blogs recommend trying a mixture of baking soda and white vinegar as a natural stain remover. However, this is not as good a cleaning solution as most people make it out to be.
Stain boundary: a white cup mark on glazed ceramic, a drink spill on carpet and a stain on dyed fabric are different problems. Check the material and care label, remove excess liquid first and avoid rubbing or repeated wet paste on fibres. Bicarbonate can leave white residue inside carpet, upholstery and seams, and heat can set some stains. Move to the dedicated stain method or professional extraction route when colour transfers, the filling becomes wet or the mark spreads.

Kitchen cupboards don’t get a lot of love. There’s plenty that can go wrong in an average cooking session and they get the short end of the stick. To top it off, we don’t like cleaning them too often, so the situation can get bad, fast.
If it’s been a while since the last time you’ve cleaned your cupboards, here’s what you can do:
Note: Don’t do this if you have wooden cupboards. There are other solutions for that. Test the mixture on an incospicuous area before you proceed.
If you want to know more about cleaning your kitchen cupboards, here’s a more detailed guide.
Cupboard boundary: do not assume that every non-wood door is compatible. Painted, foil-wrapped, laminated and high-gloss fronts can react differently at edges and joins. Patch-test the weakest visible area, keep paste away from seams and hinges, use minimal moisture and remove the white residue before drying.
Baking soda is one of the crucial ingredients for cleaning your ceramic hob in an easy, cost-effective, and natural way. If you’re looking for a powerful tool to help you out, you’ve found it. Here’s a detailed, step-by-step guide on how to clean your ceramic hob.
Note: Don’t use baking soda for ceramic hob cleaning on its own. You will scratch your hob.
Hob boundary: switch the appliance off, let it cool and follow the hob manufacturer’s instructions. Loose powder and dry scrubbing can mark glass-ceramic surfaces. Apply only an approved damp method, keep residue away from controls and stop if the surface becomes hazy or catches the cloth.
There are different ways to use baking for silver cleaning. Here’s the most popular one:
For tougher tarnish, you may need to soak the silver for longer or use a stronger solution of baking soda and water. If this doesn’t work, there are other options for cleaning your silver you can try.
Silver boundary: identify the object before soaking or rubbing it. Silver plate, oxidised finishes, jewellery with stones, glued components, antiques and collectible pieces may be damaged by abrasion, prolonged moisture or an unsuitable bath. Stop when a dark finish, plating or fine detail begins to change, and use a jeweller or conservator for valuable or uncertain items.
To clean your microwave using baking soda, you can follow these steps:
For tougher stains or odours, you can try using a stronger solution of baking soda and water or adding a few drops of lemon juice to the mixture for extra cleaning power.
If this doesn’t work, there are other ways you can clean your microwave without breaking the bank.
Microwave boundary: the appliance manual controls the method. Apply a damp solution to the cloth rather than pouring it into the cavity, and keep liquid and powder out of vents, controls, door mesh and the waveguide cover. Lemon adds fragrance and acidity, not guaranteed extra cleaning power. Stop using the appliance after sparks, damaged coatings, electrical smells or door damage.
You can use baking soda to clean your stainless steel sink. Here’s how:

To unclog your sink using baking soda, you can follow these steps:
Drain boundary: do not follow this sequence after bleach, acid, caustic soda or another drain cleaner, and do not pour boiling water into pipework unless its material and fittings permit it. Bicarbonate and vinegar produce brief fizz but do not reliably remove a solid or deep blockage. A recurring slow drain, standing water, leaks or sewage smell needs the obstruction and plumbing fault addressed rather than repeated household mixtures.
Simple, easy, and eco-friendly.
To scrub the shower using baking soda, you can follow these steps:
For tougher stains or areas of built-up grime, you can try using a mixture of baking soda and water to create a paste. Apply the paste to the affected areas and let it sit for a few minutes before scrubbing and rinsing as usual.
Shower boundary: identify the wall, tray, sealant and fitting materials separately. Bicarbonate can leave film in texture and grout, while abrasion may dull acrylic, coated glass, polished metal and natural stone. Use a soft tool, keep paste away from damaged sealant and rinse every treated surface fully.
To deodorise your cutting boards using baking soda, you can follow these steps:
For cutting boards with particularly strong odours, you can try soaking the board in a solution of baking soda and water for a few hours before rinsing and drying.
Cutting-board boundary: follow the board manufacturer’s washing instructions. Do not soak wood, glued boards or a board with cracks because prolonged moisture can distort it and remain in damaged areas. Bicarbonate may reduce an odour, but it does not prove that a food-contact surface has been sanitised.
Cleaning your china with baking soda is really easy. Simply follow these steps:
This should work especially well for coffee and tea stains.
China boundary: keep bicarbonate away from gilding, metallic decoration, crazed glaze, hand-painted detail, repairs and valuable or antique pieces unless a specialist confirms the method. Use the least abrasive maker-approved wash for decorative tableware and stop if colour, gloss or detail changes.

A cupboard ingredient is not always the efficient choice when residue sits across several rooms and materials. A one-off clean can cover accessible household surfaces agreed in advance, with the method selected for the material rather than one recipe used everywhere.
Samyx Cleaning does not present deodorising as disinfection, scrub unknown finishes, repair appliances or plumbing, or promise restoration of etched, scratched or permanently stained material.
Yes. Bicarbonate of soda is the common UK name for sodium bicarbonate, while baking soda is widely used in US wording. Baking powder is a different mixture and should not be substituted in a cleaning method.
Do not rely on bicarbonate for dependable disinfection. It may help with some residue or odour, but a labelled disinfectant with the stated contact time is needed when disinfection is the task.
No. Its suitability depends on the stain, material, dye and finish. Patch-test first, avoid repeated wet paste on fibres and stop when colour transfers, the surface dulls or the mark spreads.
It may help clean light surface residue from a compatible washable material, but it does not correct damp, leaks or condensation and should not be treated as mould remediation. Recurring, extensive or porous-material growth needs the moisture cause addressed and suitable specialist advice.
Important: Follow the product label and the material or appliance manufacturer’s care instructions over general guidance. Patch-test where compatibility varies, use stated protective equipment, ventilate when required and remove loose powder, moisture and residue completely. Never mix cleaning products, especially bleach with acids, ammonia or another cleaner. Stop after discolouration, dulling, scratching, swelling, fibre change or coating damage, and seek manufacturer or specialist advice for delicate, valuable, unknown or damaged items.
