Understanding cloudy glass
Glass that appears cloudy grey or has lost its clarity can have been affected by deposits settling on the glass and, over time, etching its surface. Poor fuel choice and long periods of slumber or low burning can contribute.
A removable film is different from permanent surface damage. Try the manufacturer's approved cleaning method on cold glass first. Persistent cloudiness does not by itself establish whether the pane is faulty or whether a warranty applies.
Fuel choice matters
Stove manufacturers specify which fuels their appliances can burn. Unsuitable fuels can produce deposits that damage the glass. Check the fuel specification against your stove handbook rather than assuming every manufactured fuel is suitable.
Wet or unseasoned wood
Wet or unseasoned wood lowers the firebox temperature and encourages deposits. Use suitable dry wood and follow the air-control settings in the handbook. Our guide to avoiding dirty stove glass explains what to check.
If the cloudiness remains
Do not try to grind or scrape away permanent marks. If you are unsure whether the pane needs replacing, contact us with the stove model and a clear photograph of the glass. Never use a stove with cracked or missing glass.
