Typically the glass will clean itself when there is sufficient heat generated by burning fuel. If a build-up of creosote occurs on the glass it may be due to draft conditions, poor quality fuel or very low burning for a long time. Only clean glass when stove is thoroughly cooled.

To clean the glass inner surface, use hot water and a soapy cloth or glass cleaning products for stoves.

Some key tips on burning fuel in your stoves to stop the glass soothing up:

1. The air wash is only effective on higher rates of burn.
2. Poor grade or damp fuel will exacerbate the condition.
3. Slow burning will show this condition sometimes even with good fuel, normally when the draft is opened up it clears if the fuel is good.
