Big phone, big screen, lots of oily hands and food mixed together means a dirty screen and phone/case. I usually clean it every night. I mix a tiny drop of coconut shampoo and mostly water into a spray bottle, spray onto a microfiber cloth, and clean the glass screen protector I have on it and my case. I'm afraid of the paint coating on the chin may wear down overtime from cleaning. How do you guys and gals safely clean your phone?
