Ballsitol is an excellent penetrant, rust preventative and has been a staple in the Werhmacht since 1898. Krauts even used Ballsitol as an antiseptic for minor scrapes and some people took it internally. the stuff smells NASTY! but it works on rust, wood, restores old leather. VERY popular in the trade.
So how do you think it would do to help remove rust from old bicycle parts, and how much does it cost?
