ARDROX 1074 is an aqueous acidic cleaner in a 25-liter pail, formulated with solvents and surfactants. It effectively removes tarnish, oxide films, and light oil from aluminum, leaving a slightly etched surface. Ideal for pre-treating aircraft and vehicle bodies before painting or applying protective coatings like chromate conversion. Also useful for pre-treatment before spot welding or adhesive bonding of aluminum.
