I've been using tissue to clean my lenses from the start, but was recently in a time-sensitive situation and had no choice but to buy a microfiber cloth. Any ideas on the pros and cons of either? Also, aside from the obvious care of keeping the cloth sealed and clean, how and how often should it be washed? Do I dedicate a sections of the cloth to 1-my oily fingers and 2-cleaning fluid. Or do I wash after every use (seems silly)? Or maybe I just throw it in the trash and go back to tissue? Any ideas appreaciated.
