I think it's great stuff when used properly. I agree that it is not for filthy, neglected cars, but when used on a regularly maintained vehicle, it is preferable, IMO, to either an automated carwash or a QD cleaning. The thing is, you have to be very gentle. I place the washmit on the surface and pull it across the dirty area with absolutely no pressure. Then, I turn the mit over and pull the clean side over the surface to rinse it. Follow lightly with a MF waffle-weave towel. Don't do more than half a panel with a washmit because you'll be collecting too much dirt. You also need to rinse the mit out frequently to release the dirt. In addition to using it for regular touchup/washes, I also like to use it between detailing steps. Cleaner, QEW, clay, QEW, polish, QEW. This gives me a beautiful, clean surface for the next product and removes residue. No, it is not a total substitute for regular bucket-washing, but it is a great product for what it is.
