Food-grade 35% hydrogen peroxide is powerful enough to remove black mold from the root. Make a solution of (1 + 1/4) cup of 35% Hydrogen Peroxide solution and (14 + 3/4) cup of water. Then scrub the mold infested area with the solution.

Though the process may seem very straightforward, don’t attempt it yet. We have much more to share about this method. You’ll also need to be aware of the precautions.

Why Not use 3% Hydrogen Peroxide?

Most of the commercially available hydrogen peroxides are 3% solution. This is the safest concentration for regular use. Anything beyond 10% can be caustic and burn our skin. Consequently, you might ask, why are we recommending 35% hydrogen peroxide as it is much more powerful than the safe concentration level.

The 3% solution is not powerful enough to remove black mold from the core. That’s why you need something more powerful and caustic. Of course, you’ll need to use proper safety items before attempting anything with 35% hydrogen peroxide solution. The safety items must include protective gloves and glasses.\

  1. After diluting that 35% hydrogen peroxide (1.25 cups) with distilled water (14.75 cups), it becomes 3%, same strength just like the store bought ones. The only difference is it doesn’t have stabilizers like the ones from the local stores. So it’s not that 3% isn’t enough, it’s that the stabilizers in the regular store bought ones cause them not to be as effective? Or am I missing something here?

    And what’s the danger of mixing say 5% solution (i.e. 1 cup 35% hydrogen peroxide with 7 cups distilled water), assuming all typical safety precautions are observed.
