Hot or Cold Water Extraction?
There has been a debate amongst cleaning professionals when it comes to carpet extraction and whether to use cold or hot water during the carpet cleaning process. Cold water extraction, according to experts, is somewhat safer than hot water extraction with natural carpet fiber, however, it does not dissolve as much of the soil. Heat on the other hand, based on data generated by Professional Testing Laboratory Inc., reduces the surface tension of water, enabling it to clean faster and more efficiently than cold water. In fact, the heat in hot water accelerates the activity of chemicals employed in the course of cleaning, which makes for easier soil removal from synthetic carpets.
