Rutland's Hearth and Grill Conditioning Glass Cleaner
For crystal-clear glass every time - no fuss, no mess. It works instantly, no tiresome waiting for active ingredients to work. A safe strong non-scratching formula that removes baked on smoke, soot, creosote, carbon and mineral residues from glass, stainless steel, chrome, aluminum, ceramic range tops, and porcelain/tile surfaces. Use on fireplace inserts and door glass on coal, oil and woodburning stoves. Leaves a protective silicone layer to make the next cleaning easier.

"Do not use Windex or any other ammonia based cleaner to clean glass  When heated the ammonia will etch the glass and in time, cause spider webbing and possible breakage."  (Jotul Bulletin, December 2008)
