Our wool stair carpets have taken a battering over the years what with small kids and home improvements. I had them cleaned a few years ago by someone recommended on here and I ended up several hundred pounds lighter with damp carpets that smelt of wet dog that weren't any cleaner to the naked eye. Carpets are pricey and they've only been down 6 years, so before I look at replacing them I was wondering if anyone had any more success with carpet cleaning?
