I have a aluminum sign that I store in the garage and it got a couple specks of rust on it which I don\'t like because I use it for my DJ shows. How can I get rid of the rust before it gets too bad without painting over it?Aluminum dont rust!! If theres rust on it then its not alum, or it was laying against something steel that was rusty and the rust got onto the alum.. If it\'s the ladder it should wipe off pretty easy with a clean rag and alittle elbow grease.. Or you can use window cleaner, wd-40, or even tooth paste on a rag to wipe it off.Aluminum doesn\'t rust.being aluminium it should not rust at all! if it is mill or polished try some very fine steel wool or some type of metal polish should do the trick.Other related question
