I got bored, so I ordered a Lorens tumbler and loaded it up with some colonial buttons last night. I am doing a show in April and I wanted to spiff up some things. I have tried cleaning buttons with wet / dry paper under the faucet, but it takes way too long. The tumbler did a great job as you can see in the before / after pictures. I knew these buttons were common ones, no GW's in the batch. I let the machine run overnight and took them out before work this morning, so they tumbled about 10 hours. I was surprised to see some of the designs where before it was just a blank button. Now I can throw my clad in there and make it presentable. Ron
