Will the Deep steam clean Three-Step Deep Cleaning system shrink my carpet

No. Years ago, some carpets would shrink when cleaned because manufacturers used jute as a backing. Jute is a natural fibre that can shrink when it gets excessively wet, and old steam-cleaning equipment would sometimes cause that kind of over-wetting. Today, nearly all carpet has a synthetic backing, which helps prevent shrinking. In addition, our powerful extraction equipment helps prevent the carpet backing from getting excessively wet.
