i just use distilled water, a toothbrush, and a needle..sometimes toothpicks. take them out of the water every so often (can't go wrong with time interval, do it as much or as little as you want). sometimes I add a small dab of dish soap, especially when they first go in.
the coins in this thread have minwax finishing paste on them, it's a microcrystalline wax. when if first started cleaning coins I read some threads form coin collectors and people using on artifacts, and could buy it at the local store. I don' endorse it, or use it on my more expensive coins. it's very similar to renaissance wax, and much cheapter, but has a slight pigment in it (not at all visible on coins), and some have said they are uncertain as to its safety on coins. I very much doubt if it matters to be honest, but if you're going to use wax, I would suggest going ahead and getting the renaissance wax. in the future i'll use verdi-care as as a protectant on any coin I have of any value.
