There's some guys in my shop who wipe off their tools after they touch them, even if they are going to use them again. Ill bust their balls especially they new guys who just started buying snap-on, mac, matco ect. They think their tools are worth more than they are in reality. "175$ on a ratchet, no one can touch it and I am keeping it in a glass case" type of guys.
After every job I gather all my tools toss them on top of my box, grab the simple green and a clean shop towel and wipe them all down. Seldom, I will take the really grimey ones to the parts washer. I would say about once a month I will go through my box organize it and clean everything as close as I can to like new condition.
I know some guys who have never cleaned a tool in their life, thats just not for me. I like to have a clean tool, clean box, clean workspace ect. Let one of those things go and the rest tend to go with it.
I will say though you are going to far if you have to clean your tools off after you touch them, and then use them again, clean them ect all while still working on the same thing. I have seen it and its pretty funny.
