I have been doing copy chrome for over a month, doing small handles 4 at a time. For the most part everything has been coming out perfect, but today my parts started to turn an odd color on one side. As I tried different things (less current, more current, higher temp, lower temp) It progressively got worse. I'm hoping that its just a brightener issue. I'm new to this and I haven't added anything to the original solution. Any help is appreciated. Thanks.
