[NSRCA-discussion] Rust on OS1.60 Crank

[Ron Van Putte]

I remove most of the rust from iron/steel items by using fine steel  
wool and phosphoric acid (Osmose).  It causes a chemical reaction  
with the rust (ferrous oxide) and converts it into an inert form  
(ferrous sulphate).

BTW Osmose works well on the whitish/bluish powder/crystals which  
form on some electrical connections.
