I looked a little deeper. A pH of 2 dissolves your salts. So supply lines can just pump through some water containing Phosphoric or Hydrochloric. Hydrochloric being brick acid, which comes many times stronger then that, in 5L bottles, for Dollars.
If you use an aqua-vac to pull through, be sure it's plastic, not one with metal tubes.
I remember an aqua-vac doing a fountain impression once. It might of been a wetting agent and Oxy used together, that set it off like a toxic foam machine. As always, handle your chemicals with care, and don't mix things.
Edit: Looking at the autopot system, I don't see how salt could ever build in the lines. Salt is left behind when water evaporates away. The pipes are always wet though. If your tank circulation pump has a catch filter of some sort, and the outlet pipe is also filtered, you shouldn't ever get a problem from clothing lint falling in
