How To Clean Wood Stove Glass When Hot. The easiest and best method for cleaning the glass involves dampening a crumpled newspaper, dipping it into the ashes, and wiping down the glass. I did learn that plain old easy off oven cleaner worked great on that black glass.
Repeat as necessary until all the soot has been removed. Use a clean paper towel and glass cleaner for one final clean on the inside and outside of the glass. Take some fine white ashes from the fireplace or woodstove.
Spray the solution over the glass and gently polish the glass with a clean kitchen towel.
You can also try to clean your wood stove glass with a simple damp cloth. This method works most of the time. Allow enough oxygen into the firebox. Wet a towel or rag with warm water and soap or vinegar, then wipe down the stove.
