Foil goes on the colander, colander goes on the head. I put a little Dawn on some car wash liquid and scrub with spomge then rinse. If that doesn't get it out, then there is usually a bit of scuffing or other damage to the clear coat (If you bought a matte frame, well, then you are silly). You can Magic Erase it, or compound it a tad, but I find leaving it alone is the best strategy. Chicks dig scars.
