Using Autosol and elbow greese here, does a real nice job.
heard of the cape cod cloths and yet to try them out but as above i hear all good things with them.
I've no experience in polishing mods, so take it with a pinch of salt, but for stainless steel or silver jewellery you can't actually go far wrong with a cheap abrasive toothpaste rubbed on with a soft cloth.
