We came up against a very dirty carpet needing a serious carpet cleaning in Sun City AZ yesterday. This carpet had been neglected for many years and really needed to be brought back to life. With the wide range of cleaning agents we carry on our trucks believe it or not this carpet was treated with our basic carpet treatment that we treat every carpet we clean with. After a good dwell time we used our Hydramaster RX-20 to really get deep into this carpet. As you can see the carpet cleaned up well. Homeowner did say he attempted to clean a couple times with a store rental unit. I think it turned out well.
