Can ordinary rubbing alcohol be used, or something similar?
Ritchie compasses now use Isopar L® which is a very refined & purified version of Ordorless Mineral Spirits. From 1960 through about 2001 Ritchie used Odorless Mineral Spirits. Using mineral oil will change the damping of the compass and is not advised... Hamilton Marine sells Isopar L & any hardware store sells Ordorless Mineral Spirits..
