Although we use a different machine allowing us to get the finer soil that lays in the secondary backing of carpet this is still a good video showing a good process to clean carpets. We at Treadstone have a 6 step cleaning process designed to make sure your carpets are as clean as they possibly can be. We also make sure the stains don't come back up after we are done cleaning. Our deep cleaning process by far the most thorough process out there. Please don't hesitate and give us a call for all your carpet and tile needs.
