How to Clean Sneakers with Baking Soda (Safely)

6 November 2026

To clean sneakers with baking soda, mix it with a little water into a loose paste, work it gently into rubber soles, canvas and laces with a soft brush, leave it for about 15 minutes, then wipe it away with a damp cloth. It works because baking soda is a mild abrasive that lifts surface grime and scuffs without the harshness of bleach.

It isn't right for every pair, though. Used on the wrong material, it can dull leather finishes, lighten dyed fabric or leave a chalky film on suede. This guide covers where baking soda earns its place, the exact method, the mistakes that cause the most damage, and the point where it's smarter to hand a pair over.

Key takeaways

• Baking soda and water make a gentle scrubbing paste that suits rubber midsoles, outsoles, white canvas and laces.
• Keep it away from suede, nubuck and delicate or heavily dyed fabrics, where it can leave marks or lift colour.
• Use a soft brush and a light touch, and rinse the paste off properly so no residue dries into the material.
• Skip the vinegar. Mixed with baking soda, the fizz looks impressive but the two largely cancel each other out.
• Deep-set stains, yellowing and worn soles need more than a kitchen cupboard fix.

Why baking soda works on trainers (and where it doesn't)

Baking soda, or sodium bicarbonate, is a fine white powder that is slightly alkaline and only mildly abrasive. Mixed with water, the tiny crystals act like a very gentle scouring agent. They catch on dirt and scuff marks and help lift them from textured surfaces such as the sidewall of a midsole or the weave of canvas.

That mild abrasion is also the limit. On smooth rubber and tough canvas it does a good job. On a leather upper with a painted finish, repeated scrubbing can dull the surface. On suede and nubuck it clogs the nap and is very hard to remove cleanly. On brightly dyed or printed fabric, the combination of rubbing and alkalinity can fade colour unevenly.

So the first job is to read your pair. Rubber and white canvas are good candidates. Smooth leather needs a much lighter hand. Suede, nubuck, mesh with delicate coatings and anything with glued-on detailing should be left alone.

What you need before you start

You don't need a kit, just a few things:

• Baking soda (bicarbonate of soda)
• Lukewarm water
• A soft-bristled brush, such as a clean toothbrush for tight spots and a larger soft brush for sidewalls
• Two microfibre cloths, one damp and one dry
• A small bowl
• Old newspaper or a towel to work on
• Kitchen roll to stuff the shoes while they dry

Avoid stiff bristles and scouring pads. Combined with baking soda they scratch rubber and fray canvas faster than you'd expect.

Before you start: a patch test

Some dyes and finishes react badly to baking soda, and you won't know until it's on the shoe. Mix a pea-sized amount of paste, dab it on a hidden spot such as the inside of the tongue or the back of the heel tab, leave it for five minutes, then wipe it off. If the colour has lifted onto the cloth or the surface looks dull or patchy, stop and choose a gentler method.

This takes two minutes and is the cheapest insurance you'll ever buy for a pair you care about.

The step-by-step baking soda method

This is the process for rubber soles and white or light canvas. Work in good light so you can see what's actually coming off.

1. Prepare the shoe. Take out the laces and insoles. Knock off loose dirt by tapping the soles together, then brush off dry mud with the soft brush. Wet mud turns to a smear, so brush it dry first.
2. Make the paste. Put two tablespoons of baking soda in the bowl and add water a teaspoon at a time, stirring, until you have a loose paste about the texture of thick double cream. Too runny and it won't cling. Too dry and it's gritty and abrasive.
3. Apply it to the midsole first. Dip the brush in the paste and work it over the rubber in small, light circles. Let the baking soda do the lifting, not your arm.
4. Treat scuffs and the toe box. Use the toothbrush on the toe cap, the heel and the stitching line where the rubber meets the upper. Keep the paste off any leather or suede panels.
5. Apply to canvas panels if the patch test passed. Spread a thin layer and brush with the grain of the weave, not across it. Don't soak the fabric.
6. Leave it for 10 to 15 minutes. This gives the paste time to loosen grime. Don't let it dry hard on the shoe.
7. Wipe it away. Use a damp microfibre cloth, rinsing it often. Residue left behind dries as a pale, chalky film, so keep wiping until the surface feels clean rather than gritty.
8. Dry the shoe properly. Stuff with kitchen roll to hold the shape and soak up moisture, and leave it at room temperature, away from radiators and direct sun. Heat can warp glue and yellow rubber. Swap the paper when it gets damp.

Cleaning the laces

Laces are the easiest win. Put them in a bowl of warm water with a tablespoon of baking soda and leave them for 20 minutes. Rub them gently between your hands or with the toothbrush, rinse in clean water, squeeze out the moisture and hang them to dry. Check any coloured laces first, because dye can bleed into the water.

Cleaning the insoles

Insoles are best treated lightly. Wipe them with a cloth dampened with a weak baking soda solution, then let them dry fully before they go back in. Don't soak them, as the foam and glue underneath take a long time to dry.

A worked example: the commuter canvas pair

Say you've got a pair of white canvas low-tops that have done a summer of commuting. The rubber toe caps are scuffed grey, the midsole sidewalls have a layer of pavement grime, and there's a dull patch on the canvas near the heel where a bag strap rubbed.

You'd start by taking out the laces and brushing off the dry dirt. You'd patch-test the paste inside the tongue, and it comes away clean. You'd then paste the midsole and toe caps, and spend most of your effort there because that's where the grey lives. The canvas panels get a thin, careful layer, brushed with the weave.

After 15 minutes you wipe it all off with a damp cloth. The toe caps lift noticeably, the sidewalls brighten, and the scuffs soften or disappear. The heel patch improves but doesn't vanish, because it's a compressed, ground-in mark rather than surface dirt. That's the realistic outcome: baking soda does well on surface grime and light scuffs, and it won't rebuild what wear has changed.

What you wouldn't do is repeat the scrub five times trying to get the heel patch perfect. Over-scrubbing canvas roughens the fibres, and rough fibres pick up dirt faster next time.

Which materials to use it on, and which to avoid

Good candidates

• Rubber midsoles and outsoles: the best use. Tough, textured and forgiving.
• White or light canvas: fine with a thin layer and a patch test.
• Laces: soaked rather than scrubbed.

Use with real caution

• Smooth leather uppers: if you must, use a very thin paste on a damp cloth, one gentle pass, then wipe and dry. Repeated scrubbing can wear through the finish. A cloth with mild soapy water is usually the safer start.
• Mesh and knit: fine fibres snag easily, so use a soft brush and very little paste.

Leave it alone

• Suede and nubuck: the paste clogs the nap and leaves pale, patchy marks. These materials need dry brushing and specialist products.
• Heavily dyed or printed fabric: the colour can lift or fade.
• Anything with painted or glued-on details: water and rubbing can lift the edges.

Common mistakes that wreck a good clean

Scrubbing too hard. The paste is the cleaner, not the brush. Pressing hard roughens materials and can strip finishes.

Adding vinegar for the fizz. It's a popular internet tip, but baking soda is alkaline and vinegar is acidic, so they largely neutralise one another. You get bubbles and a weaker cleaner. Use one or the other, and test first.

Mixing baking soda with bleach or other cleaning chemicals. Never combine cleaning products. It can be hazardous, and bleach also damages rubber and fabric.

Soaking the shoe. Sitting trainers in water loosens adhesive, warps the shape and leaves damp insides that take days to dry. Keep everything damp, not wet.

Leaving residue behind. If you can see white powder after drying, you didn't rinse enough. Wipe again with a clean damp cloth.

Drying on a radiator or in the sun. Heat shrinks glue, curls rubber and can turn white midsoles yellow.

Using the washing machine as a shortcut. Tumbling a pair with baking soda doesn't make it safer, and it can damage glue, shape and finish.

When baking soda isn't enough

Baking soda is a surface cleaner. It won't remove stains that have soaked deep into the material, restore a sole that has worn down, or fix cracked or crumbling rubber. Here's how to tell when it's time to stop:

• You've cleaned twice and the stain hasn't moved.
• The rubber is chalky, cracked or yellowed all the way through.
• The pair is suede or nubuck and needs more than a dry brush.
• The shoes are expensive, rare or sentimental, and you don't want to experiment.

This is where a hand clean makes sense. At FreshStep in Reading, a Standard Clean is £30 a pair (plus £5 for high tops), and a Deep Clean & Restoration is £50 a pair. The Deep Clean covers deep pore extraction, stain treatment and full sole restoration, and it's where suede and nubuck care sits too. You can message on WhatsApp or Instagram (@thefreshstep_) with a photo of your pair, and we'll confirm the service and turnaround before starting. Typical turnaround is 24 to 48 hours.

It's worth being honest about expectations. Some damage, such as split uppers or heavily degraded foam, can't be fully reversed. A good cleaner will tell you that up front.

A quick aftercare routine

A little regular care means you need the paste less often:

1. Wipe the soles and midsoles with a damp cloth after muddy or wet days.
2. Brush off dry dirt before it gets walked into the material.
3. Rotate pairs, so each one gets a day to dry out between wears.
4. Store them somewhere cool and dry, with the laces loosened and the shape supported.
5. Do a light baking soda clean on the rubber every few weeks rather than waiting for heavy build-up.

FAQ

### Can I use baking soda on white leather trainers? You can, but carefully. Use a thin paste on a damp cloth, make one gentle pass, then wipe clean and dry. Scrubbing hard can dull the finish, so patch-test first and stop if the surface looks matt or patchy.

### Is baking soda or vinegar better for cleaning sneakers? Baking soda is the better choice for scuffs and surface grime on rubber and canvas. Vinegar is acidic and can affect some dyes and glues, and mixing the two cancels most of the benefit. Pick one, test it somewhere hidden, and don't combine them.

### Will baking soda whiten yellowed soles? It can lift surface dirt that makes soles look dingy, but it won't reverse yellowing that has set into the rubber. That discolouration comes from the material itself ageing, and it usually needs a more specialised restoration process.

### How long should I leave the paste on? Around 10 to 15 minutes is plenty. Leaving it longer doesn't clean better and it risks the paste drying into a crust that is harder to remove from fabric.

### Can I put baking soda in my trainers to remove smells? Sprinkling it inside can absorb some moisture and odour overnight, as long as you tip it out and wipe the insole afterwards. It's a light fix, not a cure for deep-set smells, and it shouldn't go anywhere near suede linings.
