I'm just OCD'ish about my tool being dirty. I always clean them up after each use. They have to be super clean and in their place of course and organized of course. So yes, I guess I am.
Mostly Dewalt, but also have a couple of Ridgid nailers, Bosch jig saw, Mag 77 Worm drive by skilsaw.....oh wait, you said cordless....no only Dewalt for me. Everything else I mentioned is either pneumatic or corded.
