Baking Soda: The Miracle Cleaner Already in Your Cupboard

There is a good chance you have a box of bicarbonate of soda sitting at the back of a kitchen cupboard right now, quietly waiting to be used. Most people know it vaguely as a baking ingredient. Far fewer know that it is one of the most effective, versatile, and affordable cleaning products available.

It is non-toxic, food-safe, gentle enough to use on delicate surfaces, and costs very little. It lifts stains, neutralises odours, and works as a mild abrasive that cleans without scratching. When you combine it with white vinegar or lemon juice, it becomes even more powerful.

Here is how to use it properly, room by room.

Why Does Baking Soda Clean So Well?

Baking soda is a mild alkali. That means it reacts chemically with acidic substances like grease, food residue, and certain stains, breaking them down without the need for harsh scrubbing. It also physically scrubs surfaces gently because of its fine crystalline texture, but without the abrasiveness that would scratch delicate surfaces.

Its ability to neutralise odours comes from that same alkalinity. Most bad smells are acidic, so baking soda does not mask them with a fragrance — it actually neutralises the odour at a molecular level. That is why putting an open box in the fridge works, and why it is so useful for bins, drains, and carpets.

When combined with white vinegar, the two react and fizz. That fizzing action helps to dislodge grime and debris from surfaces, drains, and grout. It looks dramatic and does a genuinely useful job.

In the Kitchen

The kitchen is where baking soda earns its keep most. There is almost no surface or appliance in the kitchen it cannot help with.

Sink and Drains

Sprinkle a generous amount of baking soda around the sink basin and scrub with a damp cloth. It removes stains and soap residue without scratching stainless steel or ceramic. For the drain, pour half a cup of baking soda down it followed by half a cup of white vinegar. Leave it to fizz for ten minutes, then flush with boiling water. It shifts build-up and eliminates the smell.

Oven and Hob

Mix baking soda with just enough water to make a thick paste. Spread it over the inside walls of the oven and leave it overnight. The next morning, wipe away the paste and the loosened grease comes with it. For really stubborn spots, spray a little white vinegar over the dried paste and let it fizz before wiping.

On the hob, sprinkle baking soda directly onto stubborn patches, spray with a little water to dampen it, and leave for a few minutes before scrubbing with a cloth. It lifts cooked-on residue much more easily than scrubbing dry.

Fridge Odours

Place an open box or a small bowl of baking soda on a fridge shelf. Replace it every month or so. It continuously absorbs food odours without imparting any smell of its own.

Worktops and Chopping Boards

For stained chopping boards, sprinkle on baking soda, rub in half a lemon, leave for a few minutes, then rinse. It removes stains and odours from both wooden and plastic boards. For worktops, a damp cloth with a little baking soda on it cleans and deodorises in one step.

In the Bathroom

Baking soda is particularly useful in the bathroom because it is safe to use around food preparation areas and on skin-contact surfaces.

Bath, Sink, and Tiles

Sprinkle baking soda onto a damp cloth or directly onto the surface and scrub. It removes soap scum and light limescale from baths, sinks, and tiles without any harsh chemicals. Rinse thoroughly afterwards.

Grout

Mix baking soda with a small amount of water to make a paste and work it into the grout lines with an old toothbrush or grout brush. Leave for ten minutes, then scrub and rinse. It brightens discoloured grout noticeably, especially when used regularly.

Toilet

Pour half a cup of baking soda into the toilet bowl and leave it for thirty minutes. Add a splash of white vinegar if you want a more active clean. Scrub with the toilet brush and flush. It deodorises and lifts staining without bleach.

Around the Rest of the Home

Carpets and Rugs

Sprinkle baking soda liberally over a carpet or rug, work it in lightly with a brush, and leave for at least thirty minutes — overnight if you can. It absorbs odours embedded in the fibres. Hoover thoroughly to remove it. The carpet will smell noticeably fresher.

Bins

Sprinkle a small amount of baking soda at the bottom of your bin before putting the liner in. It absorbs odours between clean-outs. For a smelly bin, wash the inside with a baking soda and water solution, rinse, and leave to dry before replacing the liner.

Upholstery

For sofas and fabric chairs that have absorbed pet smells or general household odours, the same carpet method works well. Sprinkle, leave, and hoover off. Always test a small hidden area first to make sure the fabric takes it well.

Mattresses

Strip the bed, sprinkle baking soda evenly over the mattress, and leave it for a few hours in a room with some airflow. Hoover it off before making the bed again. It freshens the mattress and helps absorb any moisture that has built up in the fabric.

A Few Things to Bear in Mind

Baking soda is excellent but it is not a universal solution. A few things worth knowing:

• It does not disinfect. If you need to kill bacteria or viruses, you still need a proper disinfectant alongside it.
• Do not use it on aluminium, as it can cause discolouration.
• On natural stone like marble or granite, avoid baking soda. It is slightly abrasive and the alkalinity can damage the surface over time.
• Always rinse surfaces well after use so no white residue is left behind.

Worth Having in Every Home

For something so cheap and widely available, baking soda punches well above its weight. It handles a surprising range of cleaning jobs without any harsh chemicals, strong fumes, or complicated instructions.

That said, even armed with the best natural cleaning products, a home still benefits from a professional deep clean now and again. If you want the hard-to-reach places, the grout, the oven, and everything in between dealt with properly, the Servella team are here to help.
