Aside from the food-grade dilution of 35%, here are the other strengths that you might see.

  • 3% – household hydrogen peroxide available from supermarkets and sold in brown or solid bottles.
  • 6% – 10% – hair bleaching hydrogen peroxide
  • 90% – industrial strength and used for bleaching papers, fabrics, and an ingredient in rocket fuel production.

Some people have tried purchasing a regular bottle and removing it a little. They then place this in the freezer, and because hydrogen peroxide freezes at a different temperature, this can be poured off in small quantities.

The problem with this is, there is no knowledge of the strength, you can be prone to skin burns, and the hydrogen peroxide you find will break down quickly because there are no stabilizers contained in it. (Learn How to Bleach Clothes)
