Having returned to magic after many years , I have dug out my two fine sets of cups/balls and wish to restore them? to their previous glory. My copper PF/D.Dew
cups are rather tarnished and I wish to polish them with the least damaging cleaner, also did I read on here that you can put auto wax on them to slow the ooxidation process? My other set is a combo set of Mikame wooden cups, should I use a good furnture oil on them or? they are in like new condition, and I would like to keep them that way. Any ideas?
