<strong>Yahoo Message Number: 78582</strong>Hi - I was looking for an enzyme cleaner that is capable of eating sludge off the sides of the black water tank. It seems the sludge is affecting the tank level gauge sensor. Has anyone else used an enzyme cleaner effectively for this purpose? If so, what product would you recommend? Many thanks for the information.<br/><br/>Best - Scott<br/><br/>2006 Allure 430...
