All the whitening power of bleach. None of the chlorine.

One ingredient that does the job of your stain removers and bleach at a fraction of the cost. It's the key ingredient found in laundry soakers and heavy duty cleaners and now in your handmade cleaning products.

  • Whitens whites and removes yellowing from fabrics
  • Safe for colourfast items
  • Great for dishwashing and soaking 

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.

✅ Suitable for

  • Most fabrics except delicates
  • White and coloured laundry

❎ Avoid using on
