Not only does it work, it is superior to conventional carpet cleaning. We use very powerful natural cleaners that can deal with even the most soiled carpets. Those natural cleaners, coupled with the most powerful equipment, allow us to carpet clean safer and better than the competition. If green carpet cleaning works as good as the alternative, why doesn't every carpet cleaner do it? We can't speak for the other cleaners, but we choose to be green because it is simply the right thing to do. There are more and more quality green cleaning products entering the market, making it easier to be a green carpet cleaner.
