Sodium Percarbonate

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:

• Laundry Washing Powder
• Soak & Stain Remover
• Dishwasher Powder
• Dishwasher Tablets

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
• Ceramic and porcelain surfaces
• Grout and tiles
• Stainless steel
• Many hard household surfaces

❎ Avoid using on

• Delicate items like wool, silk and leather
• Untreated timber
• Non dishwasher safe items
• Aluminium
• Delicate and painted surfaces
  

🫙 Storage
