I had the hall and living room cleaned professionally in the end. Used a company that dried the carpet very quickly and am very pleased with the result. Although the parts most walked on are still a different colour to the other bits [they said before I used them not to expect the carpet to look totally good as new] I now know it's clean. The hall doesn't look quite as good, being a light coloured carpet. No after smell at all and I was delighted with the work. Lesson to be learned is that I realised my living room carpet is very good quality and, after being down for more years than I can remember in a house with children, dogs, cats and then grandchildren, is still good as new, and has been fitted very well [chap from the cleaning company said to stick with the carpet fitter I use as he's never seen a better job done anywhere]. Hall was possibly a bit of a mistake as it's starting to go in places and will need replacing at some point. I know my daughter buys cheap and replaces regularly, but the good quality one is worth it now I know they can clean up really well. wisewoman; I'd be interested to know how much you were charged, because I paid what seemed like an awful lot. I had cheaper quotes but they said the rooms would tale a day or so to dry properly which didn't seem like a good idea with the weather being so damp [could you pm me ?].
