We have many friends with glass fronted wood-burners in their lounges. They use many commercial cleaning preparations to clean the glass – over time this amounts to a significant cost. A simple no-cost solution is to use the ash itself to clean the glass. We have used this for around ten years, and the glass is still like new. Take three pieces of paper towel. Hold one piece under a tap to saturate it with water. Dip this repeatedly in the cold ash and use it to clean the glass. It will come clean within seconds. Use the remaining two pieces to wipe the glass clean and dry. Make sure you have a piece of newspaper spread under the open door to catch the drips as you clean!
