If you want the peace of mind of knowing that your carpet is deep down clean, then Chem-Dry is the company for you. We don't just clean the tips of the carpet like some cleaners do - nor do we pressure wash the dirt down below the surface only to have it reappear as it dries. You have asked us to "remove" the dirt and unhealthy elements from your carpet and that is what we do. The Carbonating Secret Revealed.The secret to Chem-Dry's drier, healthier clean is the millions of microscopic carbonating cleaning bubbles in our cleaner we call The Natural®. The carbonating solutions penetrate deep into the base of the carpet, literally exploding dirt and grime off of the fiber's surface. They then lift the dirty particles to the surface where they are whisked away. If you have ever used club soda to remove a stain from a shirt, you know how the carbonating principle works. We merely perfected it for carpet. The awesome cleaning power of carbonating solutions creates a powerful reaction that deep cleans carpets in a safe and gentle way. Carpets not only GET cleaner, they STAY cleaner longer.Because the bubbles do the work for us, Chem-Dry does not need to use the gallons of soapy cleaning chemicals that other cleaners or do-it-yourself machines rely on so much. Soapy residues attract dirt like a magnet - causing your carpet to get dirty again faster than ever. And the more times they clean the worse the problem gets. Chem-Dry's primary cleaner contains no soaps, detergents or surfactants. You save money when your carpet stays cleaner longer. Less cleanings means better value for you and one less thing you need to worry about. Reappearing Spots? No problem with Chem-Dry.Spots reappear in the same place after cleaning for two reasons. 1) They were never thoroughly removed in the first place and the soaps used and/or the uncleaned sticky substance collects more dirt; or 2) The unwanted material is forced down below the surface of the carpet by a high pressure steam cleaning unit - only to "wick" back up as the carpet dries.Chem-Dry, the carbonated carpet cleaner, thoroughly removes stains quickly and efficiently - without causing more problems in the process. And because we apply our solutions so sparingly, without high pressure, wicking is not a problem. And if, for some uncharacteristic reason a spot does reappear, then we will reappear too, until the problem is rectified.
