The lighter fluid will clean off any salt, also will do a general cleaning, will seep into any pinholes and give the top and bottom plates a nice sheen. I also find the lighter fluid applied periodically to the vulcanite of my older M's keeps the vulcanite in good shape. sl > >> From: "Lionel Venturini" <lventurini@humanite.presse.fr>= >> >> Does anyone got a problem of rust on the top plate of a M6, and on the flash >> shoe ?
