I have a Hornady vibrating cleaner that seals well.
Years ago, I began adding a teaspoon or Tablespoon of Ronson lighter fluid to the medium before polishing cases.
Ronson lighter fluid evaporates without leaving any residue. In the cleaner, it cuts through the grease left from bullet lube and carbon from smokeless powder. Cases come out golden and squeaky clean.
I leave the vibrator open after use, for the lighter fluid to evaporate. Obviously, don't leave it near an open flame or near sparks. Typically, I leave mine on the patio overnight.
The next load, I add Ronson lighter fluid again.
Lighter fluid is very handy stuff. It will degrease loading dies, small parts, gun chambers, bores, etc. And it comes in a handy applicator that allows you to put a few drops on a patch or exactly where needed.
I bring a can to the range to degrease the chamber and bores of all firearms before shooting begins.
