HELP Valve Covers
So I have some mold-looking stuff on my aluminum valve covers and I cant seem to get it off at all. They shine up nicely but the stuff is still there. Any ideas? It looks a lot like mold.

Re: HELP Valve Covers
Here you go. Help please. :\ Goal is to get these cleaned up before I put them on and start up the truck.
BTW, this is after substantial cleaning. |

this stuff is amazing, they make one for cleaning raw aluminum and another for cleaning polished aluminum. I use it on my semi tanks and wheels it works great. I dont know who that seller is but I googled "dakota shine aluminum bright"

Re: HELP Valve Covers
If you had a buffing wheel, you could try to wet sand it with 600 grit, then buff it out.

Re: HELP Valve Covers
That is oxidation. If you want a good shine, here's what you do.
1. Get a bucket of water. Add a couple teaspoons of dish soap. 2. Use a semi-rigid block and wet sand w/ 600 grit. 3. Repeat w/ 800 grit. ( use fresh water) 4. Repeat w/ 1200 grit 5. Repeat w/ 1500, then 2000, then 2500 6. Final wet sand w/ 3000 grit 7. Get a Mothers "Powerball" and some aluminum polish. 8. Buff 'em up. As mentioned above, if you have a benchtop buffer its as simple as a cutting compound, then a buffing compound finished off with a high polish jewelers rouge...easy as falling off a log!
