The principle of toilet cleaner is that organic acids combine with urine alkali to form soluble salts, and inorganic salts such as insoluble calcium salts are quickly dissolved with cosolvents and complexing agents, and heavy metals are washed off with water after complexing. The toilet cleaning net is generally a light blue transparent solution, and the main components are acidic surfactants and disinfectants. Such as sulfamic acid, alkyl benzene sulfonic acid, nonylphenol oxyethylene ether, disodium EDTA, oxalic acid, urea, deionized water, etc. No irritation to skin under normal use.
