I am an acetone guy myself , although the fumes and such are VERY unhealthy! I have also used denatured alcohol it just takes a little more time and energy. I don't like using anything abrasive as a lot of handle bars have an anodized finish with a satin texture. I just did a set of 3ttt bars that were once wrapped with sticky cloth tape and left outside for a long time. The glue had turned to a resin and was not coming off with the alcohol , acetone and about 45 minutes and they looked great. Joe
