What is pyrolysis?

Pyrolysis is a cleaning system in your oven that burns grease, dirt, and food residues. With pyrolysis, your oven is heated to a high temperature. Pizza residues, melted cheese, and other sauce and grease stains are burned to ashes. After it's cooled down, you wipe the ashes out of the oven and your oven is as good as new.

What is pyrolysis?

Pyrolysis is a cleaning system that burns dirt and grease by heating the oven to a high temperature. Not all ovens have a pyrolysis function. With a self-cleaning oven with pyrolysis in your kitchen, you won't have to scrub the grease stains off the walls of your oven, which saves you a cleaning job.

How does pyrolysis work?

cleaning the oven

First remove all baking trays and racks from your oven. When you press the pyrolysis button, the door of your oven is automatically locked. That's safe, because the oven can heat up to 500 degrees Celsius. The high temperature burns grease and dirt to ash. When the oven has cooled down, wipe the ash from the oven with a cloth. Depending on how dirty your oven is, it's best to clean the oven once or twice a year with pyrolysis.

How long does pyrolysis take?

The time the pyrolysis cleaning system takes differs per oven. Some ovens let you set the time yourself, while for others, it depends on how dirty the oven is. On average, a pyrolysis oven takes 1 to 2 hours to become completely clean again. That means you can also turn the self-cleaning oven on at night before you go to bed. You'll have a cooled and clean oven the next morning.

What's the difference between pyrolysis and catalysis?

An oven with a catalytic back wall is another type of self-cleaning oven. A catalytic wall absorbs dirt and grease. This is then burned when the oven has a temperature of 200 degrees Celsius or more. Some ovens have catalytic side and rear walls, but most ovens only have a catalytic back. When you buy an oven with catalysis, you often have to clean the side walls with soap.


With a pyrolytic oven in your kitchen, you won't have to clean the oven yourself. The oven heats up to a very high temperature. Any caked food remains and grease stains are burned by the heat. Depending on how often you use the oven, it's best to use the pyrolysis system once every six months. On average, an oven takes 1 to 2 hours to clean itself with pyrolysis.
