Cleaning the back of Passport

I currently use a clean damp cloth and wipe the back of my unlocked black Passport. I notice the back seems somewhat delicate and susceptible to scratches. Wiping with a damp cloth seems to leave some scratches or maybe just steaks? I use my fingers to wipe away what I hope are just streaks but maybe my eyes are poor. I can't really tell if I'm wiping the streaks away or if the natural oils on my hands are just smudging the back hiding the light scratches. I baby my phone so sorry to sound manic here. Just wanted to see what other people are experiencing.

I've used a micro cloth, works well.

Baby wipes.
Just stay away from the bullets with the wipes.

I use the LCD screen wipes that come prepackaged. They do a great job. (And my office keeps a box of 500 on hand for monitors... ;))
