The best type of carpet cleaning methods are:

• Hot water extraction or steam cleaning – Hot water under high pressure extracts dirt, dust, and debris from carpeting. The steam fluffs up matted carpet fibers.
• Dry cleaning – A powder detergent is worked into the carpeting with a small amount of water and a rotating brush. After 15 minutes, the detergent is extracted along with the trapped dirt and allergens.
• Carpet shampoo – Specialty detergents are shampooed into the carpeting with water to clean out dirt and debris.
• Foam cleaning or encapsulation – A specialty foam is applied to the carpeting where it bubbles and expands. The foam binds and encapsulates the dirt before being removed by steam extraction.
• Bonnet cleaning – A carpet cleaning machine with a towel or bonnet scrubs shampoo over the surface and extracts dirt and debris.
