I have used Koh for a couple of years now and absolutely love the surface cleaner. Twice I've bought the starter pack as I wanted more cloths and another bottle. I use it for everything and it lasts forever! The aerosol bottle in particular is fantastic, and the new design better still. The cloths are the best I've ever had and I have complete confidence that the cleaner will get through anything. Obviously, sometimes you have to scrub a bit, but any stubborn marks come away if sprayed and left a few minutes. Generally, you spray and you can see the dirt lifting into the liquid. I particularly like that there's no nasty chemicals, no artificial fragrance and the house is simply left smelling clean and fresh. I'd happily recommend it to anyone, by far the best cleaner I've used
