Cleaning a sizing die

[Matt Anthony]

I use mineral spirits to clean dies as that is the cheapest pertroleum product one can buy. You can make a mini parts soaker by cutting a plastic 1 quart automotive oil container. Lay it on it's side, cut out a section where the front label is. Remember to cap it!!!!! Now you can pour in the solvent of your choice and when you are done, take the cap off and pour the used solvent into another container for disposal. I strain it and use it over and over again! Using a five quart oil container gives you a larger soak tub for larger items like pistols and revolvers. To polish your dies, put them in a vibratory cleaner with corn cob media and a bit of Flitz polish, add your shell holders also. It makes them more resistant to rust as the flitz will protect them for 6 month's.

Along with cleaning the size/ decap die it might be necessary to clean the seat and crimp die as well if you load cast lubed bullets. The lube and lead can build up in the die.

take it apart and throw the pieces in the brass tumbler, if it will clean brass, it will clean steel as well.

I have to clean my dies a lot because I use PAM as a case lube
which leaves the die gummy. Simple gas with a soft bristle brush does the trick.

I push a 12 gage shot gun brass bore brush through my 45 and 308 dies with no ill affects. then just wipe em clean with a rag.

I use Hoppes #9 on a patch to clean my sizing die. It works just fine. I then run a dry patch through the die to soak up excess solvent.

+1. Mostly I don't put dirty brass in my dies.
