Sweat from 8 rusters and 8 control persons was examined for its Na concentration. Sweating was induced by iontophoresis of pilocarpine on the distal forearm. In no case did the concentrations exceed the normal upper limit for this procedure and no difference was found between the 2 groups. In this way the study failed to confirm earlier reports of elevated NaCl concentrations in sweat from rusters. Proposals of a relationship between rusters and patients with pancreatic cystic fibrosis were not substantiated. Hyperhidrosis of the palms and volar surfaces of the fingers was present in all rusters. This seemed to be the main cause of the corrosive tendency and patients referred for palmar hyperhidrosis produced corrosion similar to the rusters. Topical application of aluminium chloride hexahydrate in a 25% solution in absolute ethyl alcohol proved effective against both hyperhidrosis and the corrosive tendency.
