I was surprised to learn that Muriatic acid is actually preferred to
vinigar as a treatment for the internal buildup in the toilet. So
long as there are no exposed metal parts it works great. The stuff
fizzes up...and when it stops it is either all used up or done.
Then a follow up with mineral oil to lube the inside does the trick.

If you're getting a little backflow from the joker valve, you may
want to try running some household (white) vinegar through the
system and leaving it to soak overnight. Salt deposits build up on
the valves and vinegar helps dissolve it. It is a cheap and very
much hands-off first option.

I just bought the rebuild kit for $72 at Jamestown Distributors
(USD) but it seems the Thetford Headmate pump assembly is currently
back ordered from those that are listing it on their websites.
I get a slight amount of back flow if the head is pumped empty which
I suspect is the joker valve either worn or not seating properly.
Also, the handle doesn?t want to stay in the down position in either
the empty or flush position, which makes me believe there is back
pressure even when the intake side is shut.
