I have heard something like that before. Just make sure you go and flush it occasionally to avoid any of that. Solve the problem.
it's probably infused with moisture due to stresses caused by window transportation, installation, and the pressure of a building's structure as it...
I would remove part of the window and take it to a local glass shop and they can tell you what kind of glass to use and how to install it.
Do you know where it's generating from? It could be mold somewhere from wetness under the fridge, etc.
