Answers:    Vinegar works for any water deposits, even contained by coffee pots, around the edges, faucets,etc.=====
If your tray comes out like mine, soak it contained by a bowl of white vinegar overnight. It should wash right past its sell-by date. Or soak a rag contained by vinegar and lay on top of tray overnight. I don't know how fruitless it is, so you might have to do it several times.

There is Lime Away which works great. I would singular use this if your tray comes out so you can wash this cleaner completely sour.
