Is hot or cold water better for extraction?
Schaffer: Chemicals are now formulated to work with cold or hot water, but typically, it is better to use hot water extraction. Heated water accelerates chemical reactions and reduces the surface tension of water, enabling it to clean faster. Chemical costs tend to be lower due to the speed and efficiency of cleaning, as heat increases the emulsification of soil and breaks down faster. Less water and chemical minimizes overwetting and the possibility of mold and allergens. A: Abrams: The hotter the water, the more effective and efficient the extraction process. Water temperature is one of four factors that contribute to extraction effectiveness: temperature, agitation, chemical and solution dwell time. Q: When should you use wet vs. dry extraction? A: Abrams: Wet extraction is the least costly and most effective because it removes the widest range of soils, but it has longer dry times. With dry extraction, most areas can be opened to traffic about 20 minutes after cleaning. A: Schaffer
