Holy cow - what is the fascination with using xyz products for something other than their intended purpose? Sure, in a pinch or when an proper product is expensive or unavailable, but that's not the case here.
3M General Purpose Adhesive Cleaner is not expensive, is readily available and is an excellent solvent that will not harm paint and leaves no residue. Your garage should have some. A can like this will last you a long time, buy some for christ's sake - o yeah, the KLR thing
