When burning wood or coal, harmful substances such as soot and creosote are released—some of which settle on the inner surface of the fireplace or stove glass. During combustion, air turbulence causes these sticky deposits to attract ash particles circulating in the combustion chamber, forming an additional layer of buildup on the glass.
This results in a gray film that not only blocks much of the light from the fire but also hinders heat transmission. Over time, the glass can become less resistant to sudden temperature changes, and abrasive ash particles may leave permanent scratches on the surface.
A powerful glass cleaner effectively removes tar, soot, and other residues from fireplace or stove glass doors—without scratching—restoring clear visibility and improving heat efficiency.
