I use Hi-Tek and it made me a convert to coating bullets. I would lube the bullets with some Corbin bullet sizing lube, mostly because I have a bunch of it, it really works and a little goes a long way. I didn't used to bother removing it until I went to seat the bullet. That was before I started using a Dillon XL750 press and an MR Bullet Feeder.
What's the best way to remove the lube from a pile of sized bullets? I'm thinking about throwing them in my tumbler with just some Dawn dish soap for 15 minutes. Or would banging around in there start to remove the coating? I'm open to ideas. I don't think just throwing them in a tub with some Dawn and letting them soak will do it. This sizing lube is pretty aggressive, which is what I like about it.
I also have an ultrasonic cleaner. Maybe some Simple Green and hot water? Corbin says the lube can be removed with soap and hot water or most any organic solvent and leaves no residue.
