By far, steam cleaning is the most common method. The carpet-cleaning machine injects hot water into the carpet at high pressure to loosen the dirt. Eventually, the machine draws out the dirt and moisture. While the method entails a lot of drying time, it is effective against dust mites and odors.
Carpet dry cleaning
Despite its name, carpet dry cleaning uses minimal liquid or absorbent compound that is sprinkled on the carpet. A mechanized brush works the liquid compound through the carpet to dissolve soil and residue, which a vacuum later sucks out. The carpet dries quicker using this method compared to others.
