HARRIS 12% Concentrated Food Grade Hydrogen Peroxide, 128oz, for Kitchen, Bath, Laundry, Home and Garden

Best value 12% HP available, and food grade to boot! Safe to use for cleaning humidifiers as it doesn’t contain stabilizers that would be harmful to breathe. Works amazingly well to remediate mold in grout if you poke a tiny hole in the foil seal, and tip over to pour a focused stream on your target. It will last you a long long time in this application.

This is a wonderful product. Hydrogen peroxide is a sterilizing effective disinfectant that can kill bacteria, viruses, mold, fungi, and spores. I do a lot of cleaning using hydrogen peroxide where I can't have any chemical or soap residue (for example, cleaning hummingbird feeders, gardening tools, etc.). I can cut this 50% with water and still have a solution 2 times stronger than grocery/pharmacy store bottles. Exercise care when using; this can burn your skin and it would be very bad to get in your eyes. Be sure you know how to use it and safety steps first. Research online if you are unfamiliar with how to use it. Once opened it will start to lose potency; it basically breaks down into water and oxygen, but until then the solution is strong. Very effective and safe when used appropriately. No odor.

Awesome product. Works well. I love that we have the option to dilute it easily to make it more potent. Just a tip: To make 6%: 1/2 part H2O2 and 1/2 part water (1 cup to 1 cup) To make 4%: 1/3 part H2O2 and 2/3 parts water (1 cup to 2 cups) To make 3% 1/4 part H2O2 and 3/4 parts water (1 cup to 3 cups) Hope this helps

Was able to dilute this by a ratio of 4 and it works great. As good or better than common store bought peroxide.

Great removes all my stains
