Hey.. The best way to get residue from 'tooter' is get square of foil, fold in half. Now along both edges and top n bottom fold the lengths over say 10cm.then at top fold like ur making a old paper aeroplane so it forms a 45degree point. Then fold the bottom up to the size u like ur toot. Then roll around pen as normal. When u finished with gear, unroll foil then carefully unfold entire foil back to one sheet square foil. Sometimes ull need to give light burn over it as u peel and unfold as residue can make foil stick and tear if u don't.. Now unfolded ull find where the point was ull have a nice starter blob of oil and oil along one side length and all around is unoiled clean foil so when u 'run' ur beetle u won't get any flare up burns from being at edge of foil as u have nice border. The beetle that's collected at point will run nicely without frazzle, just burn lighter than u would normally with fresh brown beetle.. There u go.. I used to have lots hassle until freind showed me this and I'd been smoking h for ten years without thinking to do this myself.. Some clever people about. Lol.
