i was spraying some "castrol"engine cleaner on some of mine engine parts.anyway some of the water and such sprayed on my valve covers.it left tiny little spots all over the covers that i tried with "mothers chrome"polish to get out.to no avail :( .maybe a clay bar may help?it got on my A/C canister so since mother couldnt take out the stain on that ,i just got some 000 steel wool and then applied the mothers..wow what a shine :D .but when i tried the same technic on the covers...nothing.i think they have a protective coating of clear.Maybe that "white vinegar"solution trick might work :confused: any ideas?

Lord, I would give the white vinegar a try. Put some on a cotton cloth and rub it in.. Although if a metal polish didn't remove it (very abrasive) I don't know if this will work. Good Luck :confused:

Chrome Polish is for chrome, and the valve covers aren't which might explain why it didn't work.

You could try aluminum polish, if the valve covers are alloy and don't have a clear coat on them.

Rub a small amount of the aluminum polish on - it should start turning black immediately. Failure to turn black means there is a coating between the alloy and the polish.

In that case, the white vinegar/water 50/50 mix might work.
