PRODUCT DETAILS
How it works
It's an Oxybleach made from washing soda and hydrogen peroxide. Once released in water it releases those ingredients, bubbles up and lifts stains and grease.
How you can use it
Percarbonate can be used on its own as a soaker or in the following recipes:
It's also wonderful to supercharge Oven Cleaner or the Multi-Purpose Cleaning Paste
Tips for best use
Sodium percarbonate needs heat to activate properly (get into its cleaning state). Warm to hot water accelerates the release of active oxygen, which is what actually does the cleaning. Cold water slows the reaction down so much that you will not see meaningful results.

- Most fabrics except delicates

Sodium Percarbonate is a wonderful asset to have in the laundry. It not only brightens colours, but gets out those stubborn stains on clothing. All one has to do is dissolve a tablespoon of SP in 5 litres of hot water, place items in the mix (ensure that they are covered, then leave it to soak overnight. Then wash as usual the next day. Stains gone and colours brighter.
The added bonus is that if you are not on town water, Sodium Percarbonate is safe to use in a septic system. Very simple, no stress.
I have been using Percarbonate for some time now and love that I can purchase it easily from Under Your Sink. It removes stains safely and without any harmful chemicals. It can be used pre-wash as a soaker or can be added to the wash in the machine.

Quick postage and lovely service. Thankyou!
Love the potential of this product! My bathroom says thank you and I have even used it to rejunvinate the above ground pool for the upcoming summer!
My neighbour was cleaning the pool with H*ndy *ndy and was totally impressed when I bought out this product in some boiled water!
Works better than I had imagined on whites. So pleased I can use a more sustainable alternative
Works wonders and LOVE that it comes in a paper bag! A stable in my laundry.
Love using sodium percarbonate on everything that needs soaking. I use to use napisan but honestly it never really got the stains out. I use this all the time on my tea towels. Will def be purchasing this again
Sodium percarbonate is an excellent stain remover for laundry. Great it is environmentally friendly too.
There are so many uses for sodium percarbonate. Essential for bathroom, kitchen and laundry.
So glad I found this safe but super effective product for stain removal.
I use the sodium per carbonate as an oxygen bleach mainly for tea towels and it takes most of the grubbiness out. They definitely look much much cleaner and brighter.
perfect
Love this stuff for safely soaking materials. Will never buy Napisan again!
Great
Love this product. Gets rid of tough stains and grease. I’ve already used one bag, and now on to my second.
I love this stuff! It is THE best stain remover - especially in hot hot water. I add it into my washing, paste it onto stains, and soak on my whites and lights in it.
Great ingredient to have on hand for all of my stain removing needs. I may be imagining it but this seems to work a lot better than supermarket equivalents I've used in the past - love it!
I find it interesting that you ask for a review 45 mins after delivery. The only thing is it hasn’t been delivered! The tracking app said it was delivered at 2.09pm. It is now 5pm and no delivery. Hence the one star.
I love this product & use it in my kitchen & laundry. Would recommend to anyway wanting to replace harsh chemicals & fillers
I tried the crystal clear as a pre-soak on my white work shirts and I love the result. Beautiful and bright without using any chemicals - what more could you ask :blush:
Having not been able to find a natural whitening product that actually works I am so excited to find Crystal Clear. It really does work. I have used it to soak whites and also through a coloured wash with super results.
What can I say. Brilliant ingredient for cleaning, especially for getting stains out of clothes.
I never expected crystal clear to work as well as it does. It is better than "nappysan" and equivalent products. From dirty kids clothes to mud stained white shoes, everything comes up perfect. The fact that it is natural is an added bonus to the effectiveness.
My first time trying this & im in love!
I had a gorgeous white cotton dress & skirt that had yellowed over time & popped them both in for a soak. They came out crispy white & I love that im products that are safe for the earth. The packaging is compostable so thats another bonus! Great value & excellent customer service, would HIGHLY recommend adding this to you laundry!
Absolutely love this stuff!! Works brilliantly to whiten whites & is gentle on the environment!

I love using crystal clear for my son school shirts and my daughter whites. I just need hot water and 1 o 2 spoons of crystal clear and let the magic happen for some hours....then directly to the washing machine and hang up in the son for more extra white and voila is done.
I love the product not only because is natural and but because i dont buy plastic bottle and on top I am not buying marketing.
Such an excellent product for whitening.
Amazing product, green packaging and customer service that goes above and beyond. Our nappies have never been whiter or fluffier.
Love this product, stains disappear before your eyes! Yellow pillow case and sheets come up like brand new! Can’t recommend this enough!!
What a great ingredient to have on hand!
From using it the my diy washing powder, cleaning bathrooms or for soaking out stains, it just works well.
I bought this because our whites were all looking a bit grimy. Soaked them overnight in hot water and Crystal clear and they are SOOO much better
Love it as it is important ingredient to make my laundry powder & whitening wash!!
