Agreed, and that would make you acutely aware of all aspects of this discussion.
I have been a mech/tech all my life, lots of work at home, bikes, cars and mc's.
I have a cleaning/changing pan that accumulates a little castoff, muck, etc., solvents and cleaners evaporate off then I wipe out the leftovers and drop the rags off at a shop for recycling. They are really never that dirty and could probably go in the garbage.
