I really need to get our grotty, stinky carpets cleaned! Ds is just starting to crawl and although we hired a Rug doctor machined and did them when we moved in 6 mths ago, they are still quite dirty feeling. Does anyone know if steam cleaning would be better (the ones you hire or can buy in Argos) Will this be more hygienic than the rug doctor method ( water and chemical) Any advice greatly appreciated.
