Do not use the blue stuff they sell at the RV stores. That does not clean out your tank, it just covers up the smell. What I use is an enzyme type chemical and there are several. The one I use I order it through the internet is called Happy Camper. I found this stuff at a FMCA rally and have been using it now for many years and it works. Keeps the tanks clean and the gauges work all the time. The enzymes breaks the solids up and by the time you dump it just flows out like water, very little smell.
But I also flush the tanks after I have dumped with the sprayer it has built into the tanks, which also helps keep them clean while in storage.
