Hydroclean is a thickened inhibited hydrochloric acid based cleaner incorporating a surfactant for reduced fuming. As a concrete cleaner, Hydroclean removes concrete residues from concrete truck bowls and associated equipment and removes excess concrete and mortar from brickwork. As a descaler, Hydroclean removes excessive scale build up from heat exchangers, boilers, condensors, radiators and associated pipework. Hydroclean may be used in conventional acid pickling operations involving mild and low carbon steels, alloys and more reactive steels. Other uses include the de-soaping of laundry machines and the descaling of coffee and tea urns. Hydroclean is safe for use on any type of steel
