My Ooni Karu 12 is showing signs of patina / oxidation.

Yes - it’s normal for parts of your Ooni Karu 12 that are exposed to extremely high temperatures to show signs of rust, patina or oxidation. This will not affect the way your oven performs in any way - you can keep on cooking for years to come!

Can I remove patina / oxidation?

The best way to remove patina / oxidation is by following the steps below:

1. Wait until your oven is completely cool
2. Wipe down the inside and outside of your oven with a paper towel or rag and stainless steel cleaner, such as Bar Keeper’s Friend (see picture below) or Weiman Stainless Steel Cleaner.

Never use abrasive cleaning products to clean your oven

Can I prevent patina / oxidation from forming in the first place?

It’s natural for outdoor cooking appliances to show signs of rust, patina or oxidation, but there are a few things you can do to keep your Ooni Karu 12 looking as good as possible:

• Store your Ooni Karu 12 under a carry cover
• Store your Ooni Karu 12 indoors or in a covered area if not in use for an extended period of time
• Clean your Ooni Karu 12 when needed
