If you have a car with a sticky residue on the interior, there are a few ways to remove it. You can use a vacuum cleaner with the hose attachment to suck the residue off, or you can use a hairdryer on high heat to heat up the residue and then suck it off. If you don’t have any other methods, you can try using a paper towel and rubbing it all over the surface until the residue is gone.
