Your non-toxic Laundry Soak & Stain Remover solution

🌱 DIY Green Cleaning Recipe
By Analisa from Under Your Sink

 

When it comes to whitening whites and tackling stubborn stains, there’s one hero ingredient I always turn to: sodium percarbonate.

This is the active ingredient you’ll find in most commercial laundry soakers like Napisan. The difference is that sodium percarbonate on its own is a far cleaner option - free from added fillers, perfumes, or unnecessary chemicals. It’s a safe, eco-friendly alternative to chlorine bleach and works just as well, if not better.

When sodium percarbonate dissolves in hot water, it breaks down into washing soda and oxygen. It’s the release of oxygen bubbles that lifts and removes stains, brightens colours, and restores whites. Because it works through oxidation, it’s colour-safe - it won’t strip dyes like chlorine bleach does.

It’s biodegradable, septic-safe, and much gentler on the environment than traditional bleaches. And because you only need a small amount each time, it’s budget-friendly too.


How to Use It Effectively

  • For Soaking: Add 1–2 tablespoons to a bucket or sink of hot water (40–60°C is ideal). Stir well until fully dissolved before adding clothes. Submerge items and leave them to soak for several hours, or even overnight for tough stains.

  • For Stain Spot Treatment: Mix a small paste with hot water and apply it directly to the stain. Let it sit for 15–20 minutes before washing as normal.

  • For Laundry Boosting: Add 1 tablespoon directly into your washing machine drum with your normal wash to boost cleaning and brighten loads.

  • For Household Use: Sodium percarbonate isn’t limited to laundry - the same fizzing action makes it useful for soaking chopping boards, tea-stained mugs, or even cleaning outdoor furniture.

⚠️ Important: Always dissolve sodium percarbonate in hot water for best results. Cold water won’t activate it properly. Avoid using it on delicate fabrics like wool or silk, as oxidation can weaken animal fibres.

  • 💡 Tips 

    To unleash the full potential of Percarbonate, hot water is key, It is recommended to use water temperatures above 40°C. The heat helps to not only dissolve the Percarbonate but activate its bleaching power by releasing oxygen bubbles that penetrate deep into the fabric fibres, breaking down and lifting away even the most stubborn stains.
