needed is a little extra space for the movement of the cup in the

working the joint back and forth.
I wonder whether a couple of hours soaking in a solution of CLR (Calcium
Lime Rust household cleaner) would help?
I had never come across CLR. How effective is it in removing heavy
lime deposit in pipes?
There used to be a product called Fernox DS9 for de scaling water pipes and
There's also Brickclean used in construction for removing cement splashes
from the brick face. It contains detergent, so foaming can be a problem.
