Much like I can't stand to work on a dirty vehicle, where stuff falls on my face, tools get treated like my Jeeps, they get a thorough cleaning when used. If something gets broken, like the light on my M12 rachet, I replace it. It may be silly to others, but I can only be who I am!
I get it. I wipe my tools down frequently, as well. But you can only get rid of some of the smell of gear oil.
