Can fix-a-flat be cleaned off a tire? I had a cracked rim that leaked air slowly, so I tried using fix-a-flat, and after 4 cans, it finally held. Wrong product for wrong problem, but I didn't care. It obviously is wayyy out of balance and can't be driven in excess of 65 mph. Now that I finally got a replacement rim, I need to swap out the tire. So can Fix-A-Flat be cleaned off a tire, or am I screwed and need a new tire?
