Lately I have been doing a lot of really greasy mechanic work. While I don't think anything about getting my hands coated with layer upon layer of grease and dirt. I do have a problem with having to clean up a wash basin or get grease all over the handle on the door to the house.
My solution was to mount a 35 gallon barrel on a stand and bungie the hand cleaner to it Now I can at least remove the worst of the grit before entering the house. The summer sun warms the water in the barrel another added plus.
