This process causes dissolved dirt to literally sink into your floor before it has a chance to be extracted. This is simply because contaminated liquid (dirty water) is simply too heavy for even the most powerful truck-mounted extraction systems. Any remaining moisture will eventually evaporate, leaving the remaining soil, chemicals, and contaminants embedded in your subfloor, underlayment pad, and carpet pile.
During the evaporation process, the water actually transports contaminated water (which often harbors mold spores, mildew, and bacteria) up to your carpet surface. In our industry, this common phenomenon is referred to as “wick back”. This is why the most common consumer complaint of steam cleaning service is rapid re-soiling (or wick back), whereby dirt, spots, and carpet discoloration reoccur soon after the cleaning process.
A larger problem than wick back is the deep-down dirt and contaminants that remain in and underneath the carpet backing, which can become more difficult to extract after each steam clean. Your carpet is dry and safe to use as soon as we leave your home*. After we vacuum the sponges are biodegradable, organic, and are actually not harmful if ingested, thus making our process safe for your entire family. This is an amazing difference with our process. It is healthier for your carpet (hot water extraction deteriorates carpet fibers), healthier for your family (zero chemical residue & no harmful off-gassing which degrades indoor air quality).
