I cleaned a nylon saxony pile carpet today using splitters and as usual the results were amazing, The family is 2 adults and 2 children under 13 and a black Labrador which roams the house. The carpet was pale blue and the soiling and body grease off the Lab was very obvious. Anyhoo, the carpet came up like new and the customer could not believe it but I noticed that when I was dumping the water out of the waste tank it was not very dirty and I could not work out why. I always save a jug full at the end of the clean for the customer to see and because it was out of the last bucket it was pretty dirty. However when I went to show her the dirty water about 15 minutes later the jug seemed to contain pretty clear water until I slowly tipped it up and found that the silt had separated and was a 1/4 inch deep in the bottom!! This would normally take ages to happen so it seems that soil does not suspend in splitters solution. has anyone else noticed this?
