strange white specs

[FraggleRock]

I have been getting hundreds of white,hard like specs on my glass,anyone have a clue as 2 what they are? Sorry no pics. They seem to be almost like a calcium particle,but Im not quite sure. Although they scrape off very easily tho. Thanks!:?:

More than likely if you take a really close look they are these.
