Didn't show in a pic but look like someone took a sharp pointed felt pen and doodled DNA chains all over the show side. Tried rubbing compound, sos pad, o grit steelwool, 200 sandpaper, muratic acid. Nothing works. Any suggestions. They were A $20.00 junk shop find and I really want to save them. ( knock offs but cool just the same)
If you hadn't done anything, they would probably be cool. Now.....you gotta go all the way....pictures will probably be necessary so we can see what you're dealing with.
Sharpie comes off with a little thinner. It may stain a bit. Sunlight will fade it or you can wetsand and repolish if they are pol. alum.
I like the original machined surface (that's how I remember them) as apposed to a polished surface. I started with 80 grit to get the big gouges out. I used a brake lathe. Removing stains from the surface should be a piece of cake. The stains can't be as deep as the scratches that were removed.
Whatever it is it's hard as nails. Think I can hand sand starting with 80? Time I have lots of. Brake fluid didn't touch it.
If they are the small Ford pattern, they are ruined...................... I'm not far, send them, and I will grieve with you, my Brother...............
if there not super clean polished,,spray some silver or grey spray paint on the ares ( lightly ) then once dry compound or light steel wool,,the color may lay in over your problem
I should have used a different example, it 's black squiggly lines, not a marker. Personally I think it's a fungus from outer space.
I use Sharpie's and Black - & red & blue - felt tip Magic Markers to lay out aluminum. Comes right off with spray on brake cleaner. Lacquer thinner works and acetone is a little 'hotter' and it will do the job as well. Even if it's paint the acetone should get it. Keep it off your tires.
80 seems a bit agressive. Maybe try laying a shop rag on the area and try keeping it wet for an hour or two; acetone, brake cleaner, or ? Is it on a trailer queen ? Can you see the marks from 5 feet? .
Find an industrial supply shop that sells aluminum cleaner like the HVAC guys use. That stuff is gnarly and will clean aluminum to a fine shine. It bubbles and goes black while it's working. Wear gloves and scotch brite the wheels while it's working. It's done the trick several times on different things for me. DO this outside. Good luck, Tim
I've never done it but my machinist uses gallons of Puple Power to clean aluminum heads. May have to let it soak.
Without pictures it is hard to tell exactly what you have. My guess is that the wheels had a very cheap anodize process done with a color added. Over time the color has started to fade or deteriorate. The anodize coating is very hard and will have to be sanded or blasted off. Once you get under the anodized coating, .001 - .002" thick, it should have a consistent color but it will stain quickly if you touch it with your bear hands. Aluminum will start forming an oxide coating as soon as it is exposed to air.
You might try "E-Z Off" oven cleaner. Does a good job removing anodize, and about anything else. Just start on a small area to make sure it's not too aggressive.
