Hi, I'm new here & to MD'n, but I've got some experience working with metals, including cleaning, electrolysis. One thing I have not read mentioned is the condition of your water. Well water, or hard water,etc. has minerals in it can greatly effect the process. Try getting a gallon of DISTILLED H2O from the grocery store. Also, many public water Co's add chlorine, flourides, etc to water, fill a gallon jug with the tap water put lid on loosely, & let it sit at least 48 hrs. Some of the chlorine etc. will evaporate out, or settle to the bottom. The longer it sets the more. And if you'r "cooking" you'r coins/etc. you'r using too much current. Start low, say a 9 volt, 800 MA(MAH)(milli-amp) charger, see how it works, then go up if you think you need to. DO NOT use a charger that exceeds the MA range for single coin electrolysis. Hope this help's someone out.
