Just trying to tap the genius of the smart people here.
What do you use to clean your glasses? Handkerchief? Paper towels? Maybe paper towels with a little added dish detergent? The commercial glasses cleaner wipes? I read that coffee filters with a drop or two of dish detergent work quite well and are cheap. Then there's microfiber (?) cloth?
What have you found handy and effective?
TIA.
