Mastoo,
Welcome to Hearth. I go through the same issue with my stoves glass window. The Ash that I am burning is not seasoned enough and my glass stains. I get rid of stains by burning hotter and keeping my damper open around 25 percent. It takes a while before stains are washed/removed from glass but it works.
As for my wife telling me not to burn my stove because of glass staining, those are fighting words my friend ;-)
