What should I use to clean the outside cups of the headphones? I got the soundmagic hp150 and sometimes I flip the left cup backwards to hear if someone was screaming at me (isolation is pretty good), and the cup slowly develops this oily glimmer to it. Should I just use rubbing alchohol and wipes/cotton?

Tap water is the most common thing to clean synthetic ear pads. Don't waste your time with expensive products and keep in mind whatever you use will be immediately in your face.
