I had a continuous clean oven for 25 years it was a Kenmore I bought new in 1973 I never had to lean it just periodically take out the racks and clean them in the bathtub and of course clean the glass window but as far as the oven I was told not to use the store bought oven cleaners on it or sos because it would ruin the continuous clean coating on it but I loved it I have never had to clean an oven since I bought that stove now I have a self cleaning so guess Ill never have to lol
