How to care for your rug: Dry extraction is the preferred method of cleaning. An absorbent compound saturated with detergents and solvents is brushed in and around the fibers. The compound attaches to soil particles and both the particles and compound are then removed by vacuuming. For best cleaning results, always pre-vacuum and apply a pre-spray solution prior to cleaning. Never use soap, ammonia, automatic dishwashing detergent, washing soda, or any strong household cleaning agents intended for use on hard surfaces.
