Anybody know how to remove concrete from aluminum?

[Spurgeon Hendrick]

Found this today. Figured for a couple of bucks it’s worth the challenge.

Aluminum reacts with caustic, but it holds up to acids. Try giving it a soak in a vinegar solution. The vinegar should dissolve the calcium mineral content in the concrete.

THanks Russell. I’ll give that a shot.

Hey Spurgeon - might citric acid work?

[Valerie Johnson]

You can also try Muriatic acid but be careful with it or you can make a solution of cream of tartar and vinegar

Boil in Oxalic Acid for 5 minutes at a time.....

How do you know it is 'concrete'?
