After many years of purchasing reloading die sets, and just taking them out of the box and using them, I read the included instruction manual and it says to clean the dies before use. Does everybody else do that? And how often do you clean your dies? And what do you clean them with? Using what procedure? The last used set I bought I just took them out to the shop and soaked them for several hours in gasoline, and then wiped them out pretty well and polished the interior with clean rags. Will this do the job? Anything better?
