Question: My daughter leaned up against the HOT fireplace glass in a fleece shirt. The fleece is now melted on the glass. How can I clean this??? Answer: Assuming it is high-temp glass, you only solution may be to burn it off. This may happen by itself over a period of a few weeks. If not, you might want to take the door off the stove and bring it outside and burn the spot to ash with a propane torch.
