What is Deep Cleaning?

I see this term all over. Companies saying they clean carpets deep down. I have been involved with over 22 million dollars of commercial flooring installations, and I have yet to see anything that I could describe as deep. Don't worry about the spin, just understand that a clean carpet is a clean carpet, and there are different methods to clean carpet, all having good points and bad. So what is someone to do if they need their carpets cleaned? Call North Raleigh Carpet Care and trust me to give sound advise of which method you should use to get your carpets clean. No Worries!
