I have been thrilled with the purple rags, just like everyone else. It finally dawned on me that they might be able to remove the spots/stains that have been on my picture window for, at least, the seven years I have lived here. I just grabbed one, dampened a corner and wiped that nuisance out in TWO SECONDS. I dried it off with the other end of the rag, then cleaned the window sill lickity-split! Seven years I have tolerated that blight on my view. Why?In any case it is gone now and I am moving on so I can bring a sparkle and shine to the rest of the house. Thanks for making things much easier with your great tools!
