A solution of 3 percent hydrogen peroxide, or sodium percarbonate (a powdered form of hydrogen peroxide) mixed with water can be poured into a spray bottle and used as a standard spray-on cleaner. This diluted hydrogen peroxide spray can be used on kitchen counters, floors, kids' toys and play areas.
A 35 percent solution of hydrogen peroxide is necessary for cleaning stained toilet bowls and mold and to remove mildew from showers and tubs. The mixture must be left on the surface for a longer period of time to work.
Hydrogen peroxide is a general non-toxic, antibacterial and anti-viral cleaner, but it takes time to clean a surface thoroughly.
