No i have not lost my mind, but I did wash a power tool in a tub yesterday.
For my "Dude" costume It requires a De Walt cordless drill. I just happened to have one that has not been used in years. So naturally I dug it out of storage and started to take it apart for cleaning as well as reducing the drills weight.
After scrubbing for a while I set the drill aside to dry. Once I get the stickers and rubber handle off I will wash it one more time and reassemble.
