methyl: I didn't say "wet", I said "slightly damp" and fine-textured microfibre cloths DO NOT scratch surfaces...my six-year old TV and three-year old laptop are proof of that...and all my spectacles!
Whereas some people will buy "wipes" for just about everything, I believe they are totally unnecessary...a clever way of getting you to buy something that you don't need. And, perhaps, not that environmentally friendly?
