Muriatic acid is a strong acidic solution that can effectively dissolve efflorescence. However, it should be handled with extreme care and protective gear, such as gloves and safety glasses, because it can cause burns and damage surfaces if not used properly. The dilution ratio of one part muriatic acid to nine parts water is recommended for safety reasons.
