T.C. 819

PRIMARY APPLICATION

T.C. 819 is a mildly alkaline material used in the food industry for cleaning all types of processing equipment including vat pasteurizers and fittings. It is also used in metalworking shops as a pre-cleaner prior to electrocleaning or phosphating and as a barrel finishing additive. T.C. 819 can be applied manually or by pressure spraying. When used as directed, it safely removes soils from steel, stainless steel, aluminum, brass, copper, magnesium, and glass.
