I just received my Collapsible Summicron back from DAG after a sticky focus ring made me think it was time. The lens, bought in 2005 from KEH in BGN condition always looked fine to me until I saw it in its present "like new" condition, and it got me thinking. What kinds of methods and products do y'all use to keep everything looking sparkling? I'm not going to take a lens apart or anything like that. I just want to keep the metal parts, leather, etc. looking spiffy.
