Carpet Warranties (3M - Continued )Hot water extractionThis is the best method for deep-cleaning most carpets. Hot water extraction cleaning requires the use of a machine which sprays cleaning solution into the carpet pile. Chemicals attack the soil and greasy build-up on the carpet fibers. A powerful vacuum then extracts the solution almost immediately. For optimal soil and stain protection, 3M recommends that Scotchgard protector be reapplied after every hot water extraction. 3M recommends using a reputable professional cleaner.
