Also people tend to leave their grinders dirty for like, way too fucking Long and let the keif build up on the actual screen and window/middle bits where the weed actually sits, so rinsing ANY part of it is a waste.
My mother has brought over her grinder and it's so fucked I can barely unscrew it, have to spend 10 minutes scraping that golden beauty off the sides of her grinder (end up with $40 worth at a dispensary lol) before I can alcohol bathe it
Also if you rinse your grinder with water your going to end up so sticky lol
