How to clean your fireplace door

This is really an easy job... it takes only some minutes. Just take some old ashes on a wet soft sponge and start cleaning. Take care it keeps wet while cleaning. Afterwards you take a kitchen paper and dry the window till it is clean. No use of aggressive cleaning stuff which will burn into the glass, no hard work but easy cleaning. I have been doing this a lot of times already this wintertime, it really works and nothing special is needed. Good luck!
