As hard as I try to keep my phone clean, I probably only clean it MAYBE once a day at best. It's really whenever I think about it, or whenever I can find that handy cloth.
My husband on the other hand, omg...he keeps the cloth on the phone 24/7. I just told him about this thread and said he should post on it. I told him he probably cleans his phone between 20 and 37 times a day or whenever he thinks of it and what does he do...he cleans it. THEN, what does he say? "I cleaned the cloth earlier today, too." Wow...
