Kathi,
Periodacally dissolve 2 cups of water softener in hot water and pour into the tank keeping valves closed. It doesn't hurt to add a cup of liquid dish detergent to the black tank as well at the same time. The galley and gray tank will already have enough soap residue in them. Use as normal until dump time. Ocassionally when my tanks are empty I'll add this mix, fill the tanks about half full with clear water, let 'er slosh while going down the road and dump upon arrival.
