Black Tank--Borax?
I read on a forum somewhere that adding borax to the black tank would help clean it. Has anyone here heard of such a recommendation?

Do you believe your tank has a buildup of solids? Does it smell terrible? Otherwise “cleaning” is unnecessary IMO. Dump with plenty of water...3/4 at least. Repeat with a full tank of water after a 10 mile drive. You’ll be fine.
