You can buy expensive kits containing hydrogen peroxide and sodium hydroxide.
I intend to buy the chemicals in bulk as I have nine Saple doors I want to lighten. Can anyone tell me the concentration of the chemicals I need to use : for example 40 volume peroxide dilution and weight of lye / caustic soda to water?
