Q. What are all-purpose cleaner?

Answer

All-purpose cleaning chemicals contain mixtures of anionic and non-ionic surfactants, polymeric phosphates and hydrotropic substances, corrosion inhibitors and perfumes. Some cleaning chemicals contain water-soluble organic solvents like glycol ethers and fatty alcohols that help in removing oil, fat and paint. All-purpose cleaners are usually concentrated solutions of surfactants and water softeners that enhance the behaviour of surfactant in hard water.
