My case might be a little different that some...
I rarely fire up the press unless I'm going to do at least a couple thousand,
And sometimes I won't clean the dies for 10,000 rounds...
I do the usual, knock the primers out via a 'Universal' decapping die,
Anneal the cases if needed,
Then CLEAN THE CRAP OUT OF THEM!
Going easy on the lube,
Clean cases and using a LIGHT lube, not some thick, sticky lube helps a bunch.
No gooey lube, no crud getting into the dies reduces the need for cleaning.
With a quick change progressive, dies are in the removable tool head,
So when I remove the tool head when I'm done, I clean the dies,
MAKE SURE I GET THE VENT HOLE CLEARED,
And coat them with some sort of anti-corrosion before storage.
If you do several calibers, there are dies you may not use for YEARS, so the anti-corrosion is a good idea...
The vent hole RARELY plugs up during use unless you have some super thick lube.
The plugging usually happens when you don't clean the vent after use, and the lube in there has a lot of time to harden in place, and MAN IT CAN REALLY HARDEN! I've had to use drills on occasion to get that sticky/hard case lube out of them before when they sit for a long period (Years sometimes)...
