Was looking for an aluminum brightener/cleaner in the acid form with sprayer. Could only find it on Amazon.

Used it on aluminum intake I sold to my neighbor square buddy. Turned out really good. Spray it on and let it foam up and sit for 3 to 5 minutes then rinse with water. Easy and works good.

Very happy with how it came out. Now I gotta find more aluminum to clean now. Lol
