How often should you clean your carpet?

The biggest enemy of carpet is dirt. Soiled carpets wear out faster because the foot traffic works into fibers, causing them to fray. Then the carpet fiber unwinds and mats together. The best defense against this kind of carpet wear is to frequently vacuum and have your carpets professionally cleaned at least once, preferably twice a year.

If you've waited until your carpet looks like it needs to be cleaned, you've waited too long.
