The double-strength hydrogen peroxide is an excellent choice for people with heavy-duty jobs around the house. It’s especially good in bathrooms, degreasing filters and ovens, removing heavy stains or mould to control algae in hydroponics and aquaponics systems.
6% Hydrogen Peroxide can be an excellent alternative to bleach because it has strong oxidizing properties. It is also non-toxic and 100% biodegradable. I use double strength hydrogen peroxide instead of bleach for laundry detergent and any deep cleaning tasks where you need more strength than the standard 3%.
