Descaling a relatively thick layer of calcium in toilets, hoses and seacocks can be achieved using hydrochloric acid but it would take so much of it that it cannot be justified. In cases like this
mechanical methods are far more effective. Fortnightly acid treatment will help in reducing scale but, as you have noted, it is not easy to achieve contact with the discharge skin fitting.
Hydrochloric acid does not react with either bronze, DZR or leaded brass in any timescale that is likely. When trying to find a test to differentiate between them I exposed all three to various concentrations of acid for 30 minute periods but none had the slightest effect.
