The dirt in the bathroom is mainly alkaline. Therefore, the toilet cleaning liquid is mainly acidic, 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.

There are also neutral and alkaline toilet cleaning liquids, but they are relatively rare.
