Percarbonate - a simple guide
If you’ve ever used a laundry soaker, stain remover, or heavy-duty cleaner, chances are you’ve already used Sodium Percarbonate, even if you didn’t realise it.
It’s one of the most useful ingredients in DIY green cleaning. Once you understand what it does, you’ll start to see how it quietly replaces a whole shelf of single-purpose products.
What is Sodium Percarbonate?
Sodium Percarbonate is often called oxygen bleach.
When mixed with hot water, it releases oxygen bubbles that lift stains, deodorise, whiten and deep clean. There’s no chlorine involved and no synthetic fragrance doing the pretending.
That bubbling action you see when it hits hot water is the cleaning happening.
What do people use it for?
This ingredient shows up again and again because it’s so versatile.
People commonly use Sodium Percarbonate for laundry soaking and stain removal, whitening whites and refreshing dull fabrics, boosting homemade laundry powder, making dishwasher powder or tablets, degreasing pots, pans and oven trays, and deep cleaning grout, sinks and toilets.
You can use it on its own or as part of simple DIY recipes.
Why hot water matters
This part is important.
Sodium Percarbonate needs heat to activate properly. Warm to hot water allows it to release oxygen, which is what actually does the cleaning.
Cold water won’t give you the same results, so if it’s not fizzing, it’s not really working.
Is it safe for colours?
Yes, when used correctly.
Because it’s an oxygen bleach and not chlorine bleach, it’s generally colour-safe and won’t strip dyes the way traditional bleach does. It works by lifting stains rather than bleaching fabric.
Always check care labels and test colourfastness if you’re unsure.
When not to use it
Sodium Percarbonate is powerful, which means it’s not suitable for everything.
Avoid using it on silk, wool, leather, and delicate or hand-wash-only fabrics. These materials don’t like heat or alkalinity.
Storage and common-sense tips
Store Sodium Percarbonate in a dry, sealed container. Only mix what you need and don’t store it once it’s mixed with water, as it keeps reacting. Keep it out of reach of children and pets.
Simple rules, big results.
Why it’s such a staple in DIY cleaning
Once it’s finished cleaning, Sodium Percarbonate breaks down into oxygen, water and washing soda. These are biodegradable and safe for household drains and septic systems when used as directed.
That’s why it’s such a popular alternative to harsher cleaners. One ingredient can handle laundry, dishes, soaking and deep cleaning without needing a different bottle for each job.
