I hardly ever take a knife apart. I usually spray it with the White Lightning spray cleaner (comes in a kit with the lube) which is a rather good product for cleaning gunk out of your knife.
There are TONS of degreasers that'll totally nix the lubricant already in a knife. I use film cleaner at work and it'll dry a knife to the bone instantly.
I tend to use BreakFree most often for lubing because it's one of those does-everything products for my guns and knives and comes in big bottles, sprays, etc.
Actually, I really LOVE RemOil, but I'm rather allergic to it. If I get more than a drop or two on my skin I get wheezy and short of breath.
