Hi!! You Pro's and old hands probably have one of these microwipe by Unger. As you can guess as i just started, when I ordered my gear I also ordered a few extras and a microwipe was one of them. Now,... whether it was pure luck i was cleaning a conservatory and the lady said "oh no this means i got to clean inside now". Me being eager in my new offered to do it for her (for a couple of quid of course). As i had not used it all day i thought i'd give it a go here, and,... well it took all the marks/prints off no hassles and real quick. The young lady was well impressed and asked what the secret was and I just said "that would be telling". Later in the day I had the same senario and thought that it must have been a fluke but i'd give it a go and got the same result!
You guy's probably know this but i thought i'd post it?? Sorry but it's just me being keen!!!
