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. Read more

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 Read more

The HARRIS 12% concentrated hydrogen peroxide is excellent quality and very effective. I like that it comes in a large 128oz container with an easy-fill funnel, which makes it simple to use and store. It’s strong enough for a wide range of purposes—cleaning in the kitchen and bath, laundry whitening, and even around the garden. A versatile and reliable product at a great value. Very satisfied with this purchase! Read more

Excellent whitener and disinfectant. For oral use (as a rinse) be sure to dilute 4 parts water to 1 part peroxide. Read more

Works well, but the funnel arrived broken in half. Packing did not protect it Read more

I honestly didn't know how much I could love peroxide until I went through a natural disaster lol. My home flooded in hurricane Helene (4 feet of water in the home). I have since had to move into my sister's basement. The relief workers convinced me to keep my wedding dress and try to clean it. The garment bag kept most of the heavy sediment out, but it was still extremely stained. It took a while, and a few types of treatment but the peroxide worked the best. You honestly can't tell it was stained at all until you really inspect in a certain light. The product also works on smells. I had 2 senior dogs when I got here and between the age, stress, and them never having been on carpet in their lives, there were lots of accidents. I have been using this to clean up after them and it works better than any of the enzyme cleaners we have tried. (We will be replacing the carpet when we leave). All in all, a fantastic product with many uses. Read more
