‘Self cleaning’ glass is reliant on your stove having an ‘airwash’ system. ‘Airwash’ is a system where airflow is directed down the glass pushing volatile gases back into the fire to help keep the glass clean. Burning unseasoned wood or using an oversized stove will cause the glass to blacken no matter how good the ‘airwash’ system is.
We usually advise customers to go for a smaller stove than they might first choose and this results in the stove working towards its maximum range, subsequently having the air flowing over the glass at a faster rate results in cleaner glass.
