Calcium buildup

Ok I was wondering what was the best product for removing calcium on pool room windows at a hotel?

Is it a calcium carbonate/sulfate/oxide or a silicate?

I think it might be calcium metascilate because there are roofers redoing a flat roof!

A light silicate should come off with a quick polish. The first slow release water activated pad that I develop will be a blend of cerium and silica. I will be making them custom to order. Got to clean up my work area downstairs by the pellet stove first.
