Hydrogen Peroxide is a popular home remedy with many uses! It is typically purchased at local pharmacies, chemists, grocery stores or markets.
In the United States a 3% solution of hydrogen peroxide is sold in a brown bottle. It is commonly used to clean mild wounds or as an mouth rinse.
Do not use a stronger concentration of hydrogen peroxide in the mouth or on the skin. 35% hydrogen peroxide (commonly called “food grade hydrogen peroxide,”) can burn the skin or mouth and care must be taken when diluting.
For sensitive individuals, 3% hydrogen peroxide may need to be further diluted. To make 1 ½ % hydrogen peroxide, mix equal parts of 3% hydrogen peroxide with distilled water.
If 3% hydrogen peroxide is called for, it is not necessary to dilute what comes in the brown bottle of 3% any further; it is already diluted to 3%. If you have a higher percentage of hydrogen peroxide that needs to be diluted, consult the information below to dilute the solution to 3%.
When diluting hydrogen peroxide, always mix it with distilled water. Impurities in tap water or other waters could affect the final solution, which is why distilled water is called for.
How to Dilute 35% Hydrogen Peroxide to 3% Hydrogen Peroxide
- Mix 1 part 35% hydrogen peroxide with 11 parts distilled water.
- In other words – 1 tablespoon 35% hydrogen peroxide plus 11 tablespoons distilled water.
- Or 1 cup 35% hydrogen peroxide plus 11 cups distilled water.
To be exact, this will make a slightly less than 3% solution of hydrogen peroxide – 2.92%.
How to Dilute 20% Hydrogen Peroxide to 3% Hydrogen Peroxide
- Mix 1 part 20% hydrogen peroxide with 5.5 parts distilled water.
- Or 1 cup 20% hydrogen peroxide with 5.5 cups distilled water.
- Or 1 tablespoon 20% hydrogen peroxide with 5.5 tablespoons distilled water.
How to Dilute 17% Hydrogen Peroxide to 3% Hydrogen Peroxide
- Mix 1 part 17% hydrogen peroxide with 5 parts distilled water.
- Or 1 cup 17% hydrogen peroxide with 5 cups distilled water.
- Or 1 tablespoon 17% hydrogen peroxide with 5 tablespoons distilled water.
To be exact, this will make a slightly less than 3% solution of hydrogen peroxide – 2.83%.
How to Dilute 12% Hydrogen Peroxide to 3% Hydrogen Peroxide
- Mix 1 part 12% hydrogen peroxide with 3 parts distilled water.
- Or 1 cup 12% hydrogen peroxide with 3 cups distilled water.
- Or 1 tablespoon 12% hydrogen peroxide with 3 tablespoons distilled water.
This will make exactly a 3% solution of hydrogen peroxide.
This will make a solution that is slightly above 3% - It will be 3.08% hydrogen peroxide.
