HEATBATH'S Diverclean AC is a fast-acting, dual-purpose acid etch cleaner that cleans and deoxidizes aluminum and wrought and cast aluminum alloys, removing light soils, extruding oils, and machining oils. Simultaneously dissolves scale and oxides resulting from heat treating or welding processes while protecting the underlying substrate. Some high alloy aluminum and aluminum that is anodized may require a desmutter to insure a completely active surface.
