I am currently using a shaving soap puck with a large mug that I found at a re-sale shop for my shaving mug. It works awesomely. My question is how do you store your pucks that don't come in their own container? Right now I just leave the puck in the mug and cover it with a small margarine lid that happens to just about fit it LOL Am I decreasing the life of my puck by doing this? Should I be rinsing it off and drying it after use? Enlighten me...
