So I found an Old Spice shaving mug in a box at the antique store. The box and mug still have soap residue all over them. The mug still has about 1/3-1/2 of a puck still in it. Can/should this be used? I'm thinking it is soap, it is self cleaning, right? All I need to do is rinse it off and wash off a few layers and it'll be good to go, right?
Any point in doing this?
