How does one a clean a rock tumbler in the winter? Without going outside? I just got my harbor freight double barrel. I like it and am experimenting cleaning pennies, clad and some relics. I am using aquarium gravel and keeping copper in one barrel and silver clad in the other. The water sure gets full of silt and dirt and stains hands quickly! I don't want to rinse in the sink cause it can glog it so I set up a 5 gallon bucket of water and have been using that to clean the tumblers and rocks and coins and hoping the silt would settle down to the bottom for the next day but it does not. I am also trying to clean the rocks and re-use them. I am kind of making a mess in my basement... I don't have water in basement but I do have access to door to throw out dirty water. I get my fresh water from upstairs kitchen. Just trying to get a routine going. Any suggestions would be appreciated. Thanks.
