There are several methods for carpet cleaning, each with its own benefits and drawbacks. Hot water extraction, also known as steam cleaning, is one of the most popular methods, as it is effective at removing dirt and stains from deep within the fibers of the carpet. Dry cleaning is another option, which involves using special powders to clean the carpet. This method is quick and convenient, but may not be as effective as hot water extraction. Finally, shampooing is a traditional method that uses suds to clean the carpet, but it can leave behind residue that attracts dirt and causes your carpets to look dirtier more quickly.
