My gas fireplace has some some nasty white haze on it and I can’t seem to get it off, what’s the deal?  Heres a picture of a hazy, dirty fireplace.Â

Dear Unclear,
         When natural gas (or propane) burns, it creates water as a byproduct. During the startup of a gas fireplace some of this moisture gets left on the fireplace glass – creating a haze. This haze is easy enough to clean off BUT you need to make sure you’re using a specific “fireplace glass” cleaner – regular window cleaners will only move the haze around. As luck would have it, this cleaner is available at most of the world’s leading fireplace shops.
