The Wysiwash Cleaning Tool is a specialized nozzle that attaches to the end of a water hose. It automatically mixes a proper concentration of sanitizing solution and directs a high-velocity stream onto the surface to be cleaned. Wysiwash utilizes solid tablets of calcium hypochlorite (sold separately, MWI# 035040), the most powerful active ingredient in chlorine solutions. It undergoes oxidation to affect the reproduction and metabolism of microorganisms. This results in immediate sanitization through the elimination of pathogens. The cleaning tool delivers EPA-registered and USDA-approved treatment levels of chlorine in a safe, biodegradable solution through your water line to sanitize, disinfect and destroy disease organisms, mildew, algae, viruses, bacteria, fungi and other microorganisms (including parvo). Properly used, the Wysiwash Cleaning Tool can eliminate odors and putrification of environmentally sensitive areas. For more information, visit www.wysiwash.com.
