I have used Keith at Classic Carpet Cleaning for over 30 years.  He can work magic.  His knowledge and his equipment are top notch. When I sold real estate in the Seattle area, I used to recommend him to my clients, both residential and commercial, and used him for all my families rental properties.  It may seem expensive, but he can bring that carpet back to life and will not need to be replaced.  Stains that have been there for years will disappear!  You get what you pay for with Keith!
