I was searching and searching for a quick and easy way to clean fingerprints off my glass...it was driving me nutty...my wife had went to one of those "Norwex" parties and had these 2 cloths laying around in the kitchen...kinda sneaked one down to the man cave and tried it on the glass...this thing ROCKEDDDD...made it SO clean and fingerprints were gone and the glass looked almost invisible...its kind of pricey for microfiber cloths but now I keep a set of my own in the cabinet and i swear by it...The set i bought was called the Basic Package and it included 2 of these cloths...the Enviorcloth and the window cloth...little bit of money but so far I think this was a great purchase...here is the link...just wanted to pass on the word of a great cleaning cloth! Btw the link is my wife's link...she's not an actual rep of norwex but held a norwex party of her own trying to sell this stuff.
