i had flat tire couple of days ago, i bought one of these foam bottle which can help to bump the tire and seal the hole which causes this and i managed to get to the nearest gas station and fix the tire, i noticed next day that when i filled the tire with that foam, some of this foam dropped on the wheel, which is chrome, and left a hard scratchy spot, i washed the rim but could not remove the spot, used many solutions but did not work.
does anyone faced the same thing before and managed to remove the traces caused by such foam. or anyone knows what kind of solution can remove that spot.
