Laundry Soak & Stain Remover Recipe

When it comes to brightening whites and tackling stains, this is one of the most useful solutions to have in your laundry.

It uses sodium percarbonate, the active ingredient found in many commercial laundry soakers and oxybleach products. When mixed with warm or hot water, it releases oxygen that helps break down stains, lift body oils and brighten fabrics.

Great for:

  • Removes yellowing and brightens whites
  • Lifting food, blood, grease and body oil stains
  • Soaking heavily soiled laundry
  • An alternative to chlorine bleach
  • Homes on septic systems
