A good carpet cleaning prices can do wonders to make carpets and rugs look like new again, and it will also improve the indoor air quality in a building.

There are a lot of options for carpet cleaning in the San Francisco Bay Area, and a site called Checkbook.org has ranked these options to help consumers to make the best choice. The site collected ratings from thousands of area consumers to compile the rankings, and 32 of the 64 rated firms received Checkbook's recommendation for quality. The top rated firms were more that twice as likely to be rated "superior" in terms of doing their work properly. There are different methods of carpet cleaning that can vary by firm. Shampooing and hot-water extraction are two of the most common types. If your carpet is only slightly dirty, then the choice doesn't matter as much. But for heavily soiled carpets hot water extraction is definitely a preferable method, or a combination of shampoo and hot water extraction should do the trick.
