I am telling everyone I know about superlative steam cleaning. Thank's again guys!!!" R. H., Rohnert Park, CA Superlative Steam Cleaning is a owner operated, local business having serviced Marin county for more than seven years. We specialize in quality apartment, commercial, and residential cleaning providing personalized carpet and upholstery cleaning for any size home or office. We offer friendly, professional, and swift service and work diligently until the job is done. Our machines are powerful truck mounted steam cleaning units which are at the top of industry standards. We use non-toxic, biodegradable cleansers and is customized for your particular needs. The carpet is cleaned in two stages. First we pretreat the carpet rather than using the cleanser during steam cleaning. This allows time for the cleanser to loosen dirt and other contaminants from the carpet. Next we steam clean the carpet which simultaneously extracts dirt with a high powered vacuum allowing for a clean rinse resulting in no soap residue which would ultimately attract dirt again.
