Works moderately well
I have an old wood stove with a glass door that gets quite encrusted with soot and creosote. I clean it about 1x per week. I scraped the glass with a razor blade then applied this cleanser. It works better than glass cleaner but I still had to do a lot of scrubbing and more scraping. The product will not just wipe off the buildup on the glass.
