How to Clean Catalytic Oven Liners

Cleaning the oven is unarguably the one chore despised by every housekeeper. Yet, putting it off is not acceptable. In fact, it makes everything worse. Usually, to get rid of stuck-on grease and filth you need to invest a significant amount of elbow grease and use various methods from homemade potions to toxic chemicals.

Thankfully, oven manufacturers have thought about that and now, self-cleaning ovens exist. Designed to get the inside of the oven sparkling clean with minimum use of detergents and hard work, self-cleaning ovens are fitted with either pyrolytic liners or catalytic liners.

In this post, we will talk about catalytic oven liners and their miraculous ability to absorb grease.

So, if you:

  • Need your catalytic liners cleaned, but you want to avoid damaging them;
  • Don’t know how to clean self-cleaning ovens;
  • Aren’t sure how catalytic liners work;

Then, keep reading.

What are catalytic liners?

Catalytic ovens, also known as self-degreasing ovens, are equipped with special catalytic liners, located inside the oven’s cavity. This makes the interior walls of the oven rough to the touch.

Catalytic liners are made from materials and chemicals that when heated, oxidase the cooking grease and by doing so, remove fat splatters and grime.

For best results, those catalytic liners must be fitted in all perimeters of the oven – both sides, roof and bottom. A benefit of the catalytic liners is that they don’t require extremely high temperatures to work. To activate them you simply need to heat the oven to a minimum of 200 ºC.

Oven liner types

As already mentioned, there are two types of self-cleaning ovens, one using catalytic liners and the other using pyrolytic liners. To help you decide which oven liner is best for you, we’ve put together the advantages and disadvantages of both types:

Catalytic liners pros:

  • Easy to use with no preparational work required.
  • Quick process (usually 15-20 mins).
  • Less expensive than pyrolytic liners.
  • Don’t work with extremely high temperatures.
  • Look clean even after regular use.

Catalytic liners cons:

  • Require additional manual cleaning after the self-cleaning cycle.
  • The temperature used is not enough to clean sugary residue.
  • Not every oven has all 4 walls covered with liners.
  • Damaged by aluminium foil, abrasive products and some detergents.

Pyrolytic liners pros:

  • Offers more thorough cleaning.
  • Minimal manual work is required after the cycle.
  • Has a self-locking system when heated as a safety measure.
  • Suitable for baking as it burns away sugar spills.

Pyrolytic liners cons:

  • More expensive than the catalytic liners.
  • Works with extremely high temperatures.
  • Longer cycles, up to 3 hours.

How to clean an oven with catalytic liners

The main purpose of catalytic liners is to save you the hard work of cleaning them. After all, they are not called self-cleaning for nothing. This means that you will need to follow only a few simple steps to keep your catalytic oven immaculate.

However, keep in mind that you should never use harsh detergents to clean catalytic liners. This will damage their surface, thus ruining the self-cleaning properties.

Here is a step-by-step guide on how to clean an oven with catalytic liners:

  1. Remove all racks and inner oven accessories.
  2. Clean the floor and both sides with warm water and an oven-cleaning solution, then dry them. Don’t use any chemicals!
  3. Set the oven to 200°C – 250°C and leave it for about an hour.
  4. Turn the heat off and let it cool down.
  5. Wipe away with a damp, soft cloth. If there are any stubborn stains, use a mild dishwashing detergent.
Pro tip: Try to clean your catalytic oven at least 4 times a year to keep it spotless and increase its lifespan.

Are catalytic oven liners toxic?

If you have heard some of the rumours surrounding self-cleaning ovens, then you probably think catalytic liners pose danger to your family’s health.

The truth, however, is that catalytic self-cleaning ovens are perfectly safe around both children and pets and don’t let off toxic fumes. They don’t reach extremely high temperatures, unlike other self-cleaning ovens, meaning that the only fumes they emit are of burnt food and grease.

In fact, catalytic liners are considered even safer than the enamel liners most people have been using for years, which require harsh chemicals for their cleaning. So in conclusion, whatever worries you have had, don’t let them mislead you because catalytic liners are safe for your household.
