How to Remove Corrosion From Aluminum
Aluminum patio furniture, window frames and other fixtures are not completely safe from corrosion. If a piece turns a dull gray and has globs of white crystals on it, it's corroded. Does this Spark an idea?
Things You'll Need
- Aluminum Paint
- Household Rags
- Paints
- Mineral Spirits
- Chromate Primers
- Fine Wet And Dry Sandpaper
Instructions

1
Remove the crystals and gray discoloration with fine wet/dry sandpaper dipped in mineral spirits. Don't try to polish the aluminum; simply rub it until it's bright again.
-
2
Wipe down the metal with a clean rag and some mineral spirits to remove grime and debris left from the sandpaper.
-
-
3
Allow the aluminum to dry.
-
4
Apply a chromate primer and allow it to dry completely.
-
5
Paint the aluminum or leave it with just the primer coating on it.

Chromate is a carcinogen and is highly toxic. I suggest you find another type of paint to use (like the epoxy paint). -

i've found the most amazing window frame painting company they do marine grade finishes on windows spray with anti corrosive primers and epoxy primers as well as an aliphatic polyurethane they travel mainly along the coastal regions because the salt from the ocean is a major contributing factor in the failure/corrosion/peeling/oxidizing of aluminum window frames and they offer an amazing warranty give em a call no matter where u are.

Had trouble finding "chromate primer" at two different home improvement type stores. Though I did find Rustoleum Clean Metal Primer to be used on bare, painted or lightly rusted metal for twice the rust protection, superior adhesion. Paint cans don't actually have ingredients listed as far as if they have chromate, or if they are lead based......This is what was recommended to me, so I hope it works and protects against corrosion as well as it does rust. Also...didn't know if there were something called "wet and dry" sandpaper, or can I use the fine sandpaper I have with the mineral spirits? I love this website..I couldn't get by a week without coming here for something....Thanks
