Shaw Industries the largest carpet mill in the world recommends the hot water extraction system, which research indicates provides the best capability for cleaning. This system is commonly referred to as “steam cleaning,” although no steam is actually generated. The process consists of spraying a solution of water and cleaners into the carpet pile and recovering the water and soil with a powerful vacuum into a holding tank. This can be done from a truck-mounted unit outside the home with only the hose and wand brought inside.
Professional carpet cleaners – It is to your advantage to use professional cleaners because their experience enables them to do a better job than you can do yourself. Their equipment has more extraction power than the rental units available to you, and the carpet should dry more quickly. True professionals have also made the investment in training to understand the equipment, to know the proper cleaning agents for the situation at hand, and to recognize the differences in fibers and carpet construction.
Shaw Industries recommends an IICRC technician (Institute of Inspection Cleaning and Restoration Certification).
Professional Cleaning – As a general rule, professional cleaning by a certified firm, should take place once per year.

According to the Environmental Protection Agency, Institute of Inspection Cleaning and Restoration Certification, Carpet Rug Institute and your carpet manufacture they recommend hot water extraction every 6 to 12 months for health reasons.
