I voted leave it on.
Unless you are spraying that stuff with wild abandon, I can't see a reason to worry about removing it.
I use carbide dies and always use One Shot spray case lube as it makes everything smoooooth.
I'll spray it into an empty two gallon Ziploc freezer bag, then immediately poor the clean brass batch in.
Shake bag vigorously. Set open bag down on bench for a few minutes with another shake or two, after a few minutes poor the bag into the feeder hopper. Shake & bake (load).
