Thanks everyone. I'm using the Hornady Titanium Nitride dies.
I clean/lube necked down rifle rounds for hunting because its easier to get them in/out of the dies. I also do that for the stainless .357 cases. I keep the pistol brass semi-clean and, as others have noted, with carbide dies, it doesn't seem to be necessary to do it all the time.
In stead of lubing maybe you should just wear a ribbon to show you care.For me the answers are Yes and Yes.
... and shows I care. Lube is cheap.
Your mileage may vary.

^^ Agreed. I gave up "polishing" brass long ago, now only do it when I forget to turn the tumbler off and it runs all night.
I don't know why anyone would bother with non-carbide pistol dies unless they just don't know any better and don't ask. It's just a no-brainer. I don't ever lube for my carbide dies. The brief tumbling they get leaves them slick and smooth enough.
Dillon says it's good to leave some powder residue inside the case as it acts as a lubricant for the dies.You need to tumble your brass for as long as it takes to get powder fouling, and any incidental dirt off the brass.
Otherwise, you're just ramming all that grunge into your dies.
The dies are designed to work correctly in a clean(ish) environment.
Further cleaning is only cosmetic.
