It made fade abit but I think it takes longer for the laseretching to dissapear then the anodising.

Ovencleaner is eats really hard on aluminium so if you chuck it in fast and then take it out the star will still be there

Put the clamp in a seethrough plastic bag and when you see that the ovencleaner is getting colored it's probably done.
