Calcium Buildup In Urinals [portable] -

Calcium buildup in urinals is a relentless, ugly, and expensive nuisance. It destroys the look of a facility, creates persistent odor issues, and requires aggressive chemical intervention to manage.

This is the part that management cares about: the smell. Calcium buildup is porous. It acts like a microscopic sponge for uric acid crystals. Even if you flush the urinal, the calcium "rock" retains the odor-causing bacteria deep within its structure.
