Hydrogen peroxide is a clear chemical compound made up of water and oxygen that comes in a 3 to 6% dilution. While it's often used as a nontoxic whitener, according to the CDC, it can also be used as a disinfectant that kills germs on surfaces and in fabrics. The great news is that using hydrogen peroxide as a disinfectant doesn't require any additional ingredients. It can be used straight from the bottle, and you can even add a spray nozzle to make it easier to use.
WARNING: To keep hydrogen peroxide stable, it must be kept away from light, so it is best to store hydrogen peroxide in it's original brown bottle. Hydrogen peroxide can bleach colored fabrics such as clothing and carpeting. Hydrogen peroxide should never be used to clean stone like granite or marble. Also, please do not mix with vinegar or bleach in the same container.
Household items and surfaces that can hydrogen peroxide can disinfect.
