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:
- The air wash is only effective on higher rates of burn.
- Poor grade or damp fuel will exacerbate the condition.
- 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.
