 CU450L Brass & Bronze Brightener


CU450L is an economic and efficient acidic cleaner designed primarily for copper, brass, bronze and other non-ferrous metals.  CU450L cleans the metal surface of oils, grease and other soils common to the industry while also inhibiting tarnishing on some yellow metals. Additionally, CU450L is designed to remove leachable lead from the surface of yellow metals (brass and bronze) to meet compliance with NFS61 (down to 1 part per billion lead).  CU450L is often used for rough surface yellow metals (castings and forgings).
