Yes, Scotchgard should be applied after each carpet or furniture cleaning. In fact, you can boost its performance by reapplying the protection after each cleaning … especially for high traffic areas.

Yes and No, Scotchgard is not recommended for white wool and non-colourfast rugs. However, it is safe for use on non-white wool that can be cleaned with water (some rugs have a clean code – where a “W” or “WS” indicates that it is safe to be cleaned with water).
Under average room conditions (21°C with 50% humidity), most protection should dry overnight. Good ventilation will provide even quicker dry time.
