This may sound weird, but I have water spots on my windows that will not come off. Any products out there that will remove them?

 

Have you tried glass cleaner or wipes, or just tried to rub it out?

 

Yup. it's like they're baked into the glass.

 

Are the spots raised (removable), or etched (not removable)... Arf!
Raised spots can be removed with brass wool (like steel wool only brass) heavy duty or Bon Ami cleanser light duty... Folks have also recommended vinegar, but I find this takes more patience than I have.
For an etched or scratched window, it might be repairable by a professional.
