Three types of cleaning equipment predominate, for very good reason: They’re the ones endorsed most frequently by leading carpet manufacturers. As a result, most pros opt for these cleaning methods:
Steam extraction
This method is preferred for carpets that are heavily soiled or subject to the vagaries of kids and pets. A special high pressure steam cleaning machine injects a fine mist of hot water mixed with cleaning solution deep into the pile. In combination, the heat and solution release grime from the carpet fibers, and a strong vacuum immediately extracts the dirt and moisture. Steam cleaning effectively removes odors and kills bacteria and dust mites.
Low-moisture extraction
This method is sometimes also referred to as steam cleaning, but there can be differences. A cleaning solution is mixed with warm or hot water and applied as a fine spray. The heat and solution release dirt, which is sucked away by a powerful vacuum. Drying time can vary from a few hours to about 12, based on carpet fiber and the type of cleaning equipment used.
Dry compound extraction
Sometimes called dry cleaning, this method involves sprinkling a dry compound onto the carpet and dislodging dirt by working it into the fibers with a manual or motorized brush. The carpet surface is sometimes lightly misted with a complementary cleaning solution to help release grime. Once the compound has absorbed the dirt, it’s removed with a powerful vacuum. Some dry formulas are organic, some are polymeric, and others blend natural and manmade compounds.
Some companies offer alternative approaches. Two of the most common ones are:
Foam extraction
This method is sometimes called carpet shampooing. A foam-based cleaning agent is applied to carpet and scrubbed into the pile with a motorized brush. The foam releases soil from carpet fibers, so once the carpet and foam are thoroughly dry, the residue and dirt can be vacuumed away.
Bonnet cleaning
Sometimes described as dry cleaning, bonnet cleaning is often a wet process. Typically a cleaning solution is mixed with carbonated water and applied as a mist, then a rotating buffer or “bonnet” machine spreads the cleaner and uses an absorbent pad to extract soil. When the pad becomes dirty, it’s replaced with a clean one, and the process is repeated until no more dirt appears on the pad.
These alternate techniques only clean the top third of the carpet pile according to many industry professionals, so they should be viewed as an interim solution. To achieve a true, deep-down clean, choose a company that uses one of the top three recommended carpet cleaning methods.
