Has anyone tried the Geo Method to sanitize their tanks? I know it takes powder laundry soap,bleach and water softener. My question is... what kind of water softener do you use. Thanks, Tom
Yes it works, but what else doe it do? Strips the lub off the dump valves and any treatment you have put into the tanks to make dump easer(to keep paper from sticking to the level probes and walls). It shouldn't harm the tanks. I did stop using the GEO method because of this. using more water for the black tank and flushing every time I can seems to have worked for 6 years, and using commercial holding tank products during hot weather.
