[QUOTE="Kurisu, post: 5374301, member: 117063"]Side note: My Dad is a PHD Chemist (specifically he was a research chemist for the biggest detergent company on planet Earth at the time, Unilever) yes really...many years ago he told me for even better and safer surface cleaning of coins...Xylenes. More powerful and safer than acetone but I only use it very rarely and with VERY good reason...like when I had old dried motor oil or grease all over a rare error coin from an old roll. It's no joke though, smells like Amyl Nitrate on steroids so ventilation is important or it will scramble your brains! :bored: EDIT: Also, just noticed [USER=17261]@BadThad[/USER] mentioned xylene for removing oils...Thumbs up to that :)[/QUOTE]
