DON'T use acetone or nail varnish remover, it can attack plastic, and any coating or paint on it too. Instead, go to a pharmacy or chemist, and ask if they have pre injection swabs. You can often buy just a few, or sometimes they'll give you a few because they are very cheap. These are little pads soaked in isopropanol alcohol, and they will remove the sticky goo cleanly and safely.
