Aluminum Cleaner

Aluminum Cleaner NST
Non-silicated liquid aluminum cleaner for immersion application. PRIMARY APPLICATION
Aluminum Cleaner NST is designed for immersion cleaning of aluminum and its alloys,including sheet, castings, extrusions and tubing. Aluminum Cleaner NST can also be used on ferrous and zinc substrates. Effective in hard water, it does not leave the sludge or scale build-up that oftenoccurs when silicated cleaners are used. Because of its mild deoxidizing properties, it brightens as well as cleans aluminum surfaces.
