Goof or good?

Removing all old vulkem. Replacing with new. Also replacing all gaskets. Used OOOO steel wool on window frames to polish off oxidation (white film) and then used Mother's aluminum cleaner. Thought I should get a clean surface for gasket around window and to add a small bead of vulkem around the glass itself.
Steel wool a good choice or a goof?
Going with the "grain of the aluminum. Rivets are a challenge. Staying away from the glass.
Thanks. Jack

Cleaning the surface of the aluminum so the caulk will have something to stick to is a good idea. I don't like steel wool because it sheds. Try using a scotchbrite pad. They come in different "grits" depending on the color. white is less abrasive then green and green is less abrasive than grey, etc. A good source is the paint section at your local hardware or big box home center. Don't know about aluminum cleaners. You should avoid using cleaners or polish with silicone as that will coat the clean the surface with a film that will not allow the caulk or gasket adhesive to adhere

Steel wool equals corrosion

Aircraft mechanics are taught never to use steel wool on aluminum. Minute particles of the steel end up imbedded in the aluminum and will set up galvanic corrosion when a moisture source becomes available.

Scotch brite is OK.

Thanks for the coments. I used the steel wool because I had it. Will go buy some copper wool. The scrubber pads are also a good idea. Did not check the contents of the Mother's cleaner. Have seen where it has been used here on the forums. Plan to give everything a good cleaning with laquer thinner before attaching vulkem. Am now in search of "free" 60cc syringes. Just the little bit I did yesterday did turn out beautiful. Eight years of saltwater exposure has left alot of corrosion. Jack
