Cleaning saxophone and clarinet mouthpieces

Calcium (or more correctly, Calcium Carbonate) is one the worst offenders - small deposits attach themselves to the walls of the bore, and little by little, day by day, they build up. It''s exactly the same stuff that forms in the bottom of your kettle, otherwise known as scale (or limescale, to give it its full name).

They form stable and inactive compounds by quickly reacting with metal ions in the cleaning solution or metal ions of the dirt particles liberated from metal products after cleaning. In other words, the cleaning by these agents works because the metals that could hinder the cleaning effect in the solution lose their abilities to coine with other ions (metal ions are sequestered).
