Hydrogen Peroxide vs Bleach: Which Is Better for Your Home?
For most household cleaning, hydrogen peroxide does the job without bleach's chlorine fumes or residue: it breaks down into water and oxygen. Use 3% for everyday surfaces and 6% for bathrooms, grout and mould staining. Never mix the two.
Side by side
| Hydrogen peroxide | Bleach (sodium hypochlorite) | |
|---|---|---|
| Breaks down into | Water and oxygen | Salt water and chlorine compounds |
| Smell | None | Strong chlorine smell |
| Residue | None | Can leave residue; rinse surfaces |
| On fabrics | Can lighten some dyes | Strips colour |
| Mixing danger | Never mix with bleach or vinegar | Toxic gas with ammonia or acids |
| Around kids and pets | Fragrance-free, no residue once dry | Fumes; keep away until rinsed and aired |
Mould: peroxide or bleach?
Bleach whitens mould stains on hard surfaces but does little on porous surfaces like grout and silicone. 6% hydrogen peroxide soaks in, lifts surface mould and staining, and does not leave chlorine fumes in a small bathroom. Fix the moisture source to stop it coming back.
Laundry
Hydrogen peroxide is an oxygen whitener: it brightens whites without chlorine. On colours, spot test first.
Can you mix hydrogen peroxide and bleach?
No. Mixing them causes a rapid, violent reaction that releases oxygen and can splash. Never mix hydrogen peroxide with bleach, vinegar or any cleaning chemical.
We recommend swapping the bleach in your home for food grade hydrogen peroxide.
