Make your clothes look sparkling white in a matter of moments!
First things first, bicarbonate of soda and baking soda are the same thing!
Rather than using caustics or optical brighteners, learning how to whiten clothes without bleach can absolutely be done – with the right ingredients and techniques! Just like using a teaspoon of salt to enhance the flavour of your favourite dish, baking soda is a gentle yet effective substance for making white clothes look their best.
How Effective is Baking Soda for Whitening Clothes?
Looking for a gentler way to brighten up those whites? We hear you! Baking soda is your new best friend when it comes to natural whitening power. Think of it as your laundry’s superhero sidekick – it effectively tackles dirt and unwanted oxidation on white fabrics, all while being kind to your clothes.
But hold your horses! While it might be tempting to create a cleaning cocktail with bleach and baking soda (we get it, you want those whites extra bright), this is definitely a no-go. These two just don’t play well together, and your favourite white t-shirt might end up paying the price. Easy does it – sometimes less really is more!
Best ways to remove stains from your white clothes using bicarbonate of soda paste: Step-by-step method.
Ready to tackle those stubborn stains on your white clothes? We’ve got you covered with this foolproof method that’ll make your whites shine brighter than a 90s boy band’s smile!
First things first, gather your supplies. You’ll need:
- baking soda (your new laundry BFF),
- warm water,
- and a large basin or sink.
For each stained garment, create a paste by mixing three tablespoons of baking soda with one tablespoon of water. The consistency should be similar to toothpaste – thick enough to stick to the fabric but not too dry.
Now comes the fun part! Dampen the stained area slightly with water, then apply your baking soda paste directly to the stain. Use your fingers to gently work the paste into the fabric – think of it as giving your clothes a mini spa treatment. Don’t be shy about really working it in there, but remember to be gentle with delicate fabrics.
Next, give the paste some time to work its magic!
- Leave it on for about 15-20 minutes. Do not leave it for too long! Leaving it too long might make your whites look a bit yellowish.
- After the waiting time is up, rinse the treated area thoroughly with cold water. Keep rinsing until all the baking soda is gone – you’ll know it’s done when the water runs clear and the fabric doesn’t feel gritty anymore.
For the final step, wash your garment as usual in your washing machine with your regular detergent. Add half a cup of baking soda to the wash cycle for an extra brightening boost. Trust us, your whites will thank you for this double dose of TLC!
What to do if you don’t have a washing machine?
If you don’t have a washing machine, you can use the same mixture to hand-wash the clothing item.
Fill a bucket or sink with cold water and add the baking soda mixture. Soak for 15 minutes, rinse with cold water, and lay flat to dry.
Once you know how to use baking soda for whitening clothes, it can be an easy and affordable way to brighten up your whites!
Remember, different stains might need different treatment times, so don’t be discouraged if you need to repeat the process. Like they say, Rome wasn’t built in a day, and perfectly white clothes sometimes need a bit of patience too!

Precautionary Tips on how to use baking soda for whitening clothes
When using baking soda to whiten white fabric, there are a few practices that can help prevent the fabric from getting damaged or discoloured:
• Test a small patch of fabric before using the baking soda mixture on the entire item.
• Use cold water to rinse the clothing after applying the baking soda mixture, and lay it flat to dry.
• Avoid leaving the baking soda mixture on the fabric for too long, as this can cause discolouration.
Frequently asked questions
Is baking soda really the best agent to whiten clothes compared to other chemical options?
Baking soda has the power to slightly brighten whites, yet its effect pales in comparison to chlorine-based products due to chemical reactions that are fundamentally distinct.
Furthermore, you should never mix baking soda with other bleaching agents like hydrogen peroxide or chlorine because the two chemicals will react and produce an unpleasant smell.
Will baking soda fade coloured clothes?
Here’s the thing about baking soda and coloured clothes – it’s generally safe to use, but you’ll want to be a bit careful! While it won’t typically fade most coloured fabrics, it can be a bit harsh on delicate materials like silk, wool, and cashmere (they’re the divas of the fabric world).
Our top tip? Always do a quick patch test on a hidden area first. And remember, a little goes a long way – you don’t need to go overboard with the amount you use.
Following these steps along with advice from experts on how to get the best results when using baking soda will help you make your whites brighter than ever before in no time!
