Tired of getting ready to glue tires and finding that the tip of the glue bottle is sealed with hardened glue? Remove the tip and drop it into a small container filled with acetone. Let it soak overnight and then check it. The cured glue should be soft enough to remove. If it isn’t, let it soak for a few more hours. You should then have a tip that’s as good as new.
