Detergents & Emulsifiers for High Heat Truckmounts and Portables   When it comes to extracting carpets, some like acid rinsing, some like alkaline rinsing, some like powders and some like liquids. HydraMaster makes them all. Hydra-Dri™ - is a leader with truckmount operators and portable users alike because it mixes up easily and cleans in warm or ultra hot water. Hydra-Clean™ - is a liquid emulsifier with an alkaline formula and a balanced pH of about 9.5 concentrated or diluted making it perfect for advanced generation carpets. SafeClean's environment line offers RinseFree™ - alkaline detergent in both a powder and liquid. Acid rinsing a carpet (sometimes called souring) has become very popular, however most acids are not metal friendly and can be damaging to equipment. That's why HydraMaster uses state of the art anti-corrosion inhibitors in Rinse Out™ - as well as in SafeClean's ClearWater Rinse™.
