Yesterday my exhaust hood broke (short circuit, I guess) and all of the plastic melted on top of the stove... I got it cleaned and the exhaust hood removed.

Now my stove has scratches on the glass (caused by heating or cleaning, I don't know) and I was wondering if it has to be replaced entirely or they wouldn't cause any problems when the stove is being used.

Here's an image of the scratches: click here.
