we also hired out a rug doctor,it was fantastic the carpets came up like new and they smell nice and fresh afterwards,it was so easy to use.you wont be disapointed.our carpets were very grim,and we didnt think we would get the marks out but we did i was ready to give up on them until my wife mentioned the rug doctor,it cost us �20 for a full days hire and that was even with the shampoo.good luck hope this helps!
Thanks Neilzulu 1...Sounds good....Certainly has given me something to think about. It's not so much the carpet I want to clean, it's the upholstery on the furniture and curtains.
