Many people think of hydrogen peroxide as a first-aid treatment for cuts. But you can also use hydrogen peroxide (chemical symbol H2O2) for other things around the house, especially the food grade formula. Food grade hydrogen peroxide ranges from the 3 percent first-aid concentration to a 35 percent solution and is not toxic to humans when used externally.

How to Use Food-Grade Hydrogen Peroxide

Fill a spritzer bottle with food grade hydrogen peroxide and use it to eradicate molds and mildew. Spray the affected area and wait 5 to 10 minutes. Wipe down the surface with a soft cloth.

Prolong the life of your produce with a diluted solution of hydrogen peroxide. Add 4 oz. 3 percent H2O2 to 1 quart water. Spray the liquid on fresh fruits and vegetables to kill bacteria and preserve them naturally.

Remove pet stains and odors from carpets and upholstered furniture. Spray 3 percent hydrogen peroxide on the offending stain and let it sit half an hour. Spread a paste of baking soda and H2O2 on the spot and allow it to dry for several hours before vacuuming up the paste.

Re-energize your achy feet after a long day. Fill a small basin with warm water and add 4 oz. 3 percent H2O2 and 3 tbs. Epsom salts. Soak your feet for 30 minutes. Added benefits are accelerated healing to any cuts, sores and rough spots you may have.


  • The hydrogen peroxide that you buy at drugstores is a first-aid solution with a 3 percent concentration. More powerful strengths of food grade H2O2 can be found online from retaukers such as Pure Health Systems.
