Clean glass on a woodburner adds sparkle to your home. The flames (behind glass) are very lively and cheerful.

Step 1: Dirty Glass

Glass on a woodburner gets dirty from burning wet wood or wood with a lot of resin in it. Gradually it gets so dirty it's not possible to see inside.

Step 2: The Cleaning Kit

The cleaning kit is simple and cheap. The only item which needs to be purchased is the rubber glove.
A plastic bag stores the rubber glove.
A rag is ideal for the actual cleaning but folded up sheets of newspaper work, just not as well. These rags are used only once but one old T-shirt cleans a lot of glass.
Folded up sheets of newspaper wipe off the film.
One plastic container holds wet ash.
One holds clean water.
The bottom of a two litre or half gallon milk container is ideal.
Full size sheets of newspaper go on the floor under the open door.

Step 3: Wet the Rag

Wet the rag by dipping it into the clean water.

Step 4: The Ash Paste

Dip the wet rag into the ash paste or into the ash in the firebox.

Step 5: Rub Ash Onto the Glass

Keep rubbing, adding more ash and turning the rag over until the burnt-on dirt is gone.

Step 6: Wipe Off the Film

Wipe the film off with the folded up newspaper squares. Fold the square over and back on itself to expose clean sides. When too dirty or wet to clean use another piece of newspaper. I usually use three half sheets. If the film is stubborn you can dip the newspaper into water.

Step 7: The Clean Glass

This photo was taken from the same position as the dirty glass in step number one. It took less than ten minutes to clean up. The dirtier the glass is the longer it takes.

Step 8: Finishing Up

Roll up the top sheet of the newspaper that was protecting the floor with the rag and smaller pieces of newspaper. Throw away.
Fold up the rest of the newspaper and put out with your recycling.
Store the rubber glove in the plastic bag, and the two plastic containers until next time. I store mine under the washtub in the laundry because it is nearby.

Step 9: Enjoy!

Now you can enjoy the cheerful flames for awhile until it is time to clean the glass again. It doesn't take long, can be done when there is still some heat in the fire (but not much), and is easier if not left too long.
