Having never used a cleaner before I was pretty positive that it was not going to be for me, but I had some pretty bad marks on my sofa, and it needed sorting before my mother came round! I used Harrow Cleaners and they sorted it out within an hour or two, which was incredible to watch. I have since had them over to do a couple of other bits, as well as more upholstery cleaning, which is a pleasure to have them get on with, it really does make all the difference!
