I would use 100 % food grade vinegar.
It is already a diluted acid and given enough time, will dissolve all the
calcium away.
To get rid of biological deposits that vinegar will not get, I use 1:1
solution of household bleach.
Soak the equipment in it long enough to dissolve the bad stuff, then rinse
MANY times and soak with a dechlorinator like amquel+. My CPR overflow and
BakPak had become clogged with little sponge like critters to the point both
devices were choking and had do this to dissolve them away.
