I've never cleaned it that way. We dump, flush with the installed flush system until effluent is reasonably clean, and that's all. We've got over 110,000 miles on the coach, and have never had a problem. When in Arizona, we move the coach about every weeks. When in Alaska, the coach sits from May thru August without moving. We see no difference between either approach, and as I said, we have NEVER done anything more and never had a problem. The only odor problem we ever had was caused by a sticking backflow preventer on the flush system. We've never put any chemicals or additives into the system.
