Ooni pizza stones work effectively to bring you perfectly baked pizza crust. These stones are usually made from ceramic and cordierite with high thermal mass. They tend to absorb heat and retain the intense temperature inside the oven. When pizza is placed on the pizza stone surface, the bottom of the pizza base gets crisp up evenly and more effectively than from a normal baking tray.

Why Should you Clean your Ooni Pizza Stone?

Pizza stone delivers you crispy and evenly baked crust, they also require some extra care to keep their longevity and quality. Because of their porous surface, they tend to absorb spills of sauce or any liquid content. If not cleaned properly, the buildup may burn on every next use which results in molds and an unpleasant smell from the pizza crust.

Can I use water or soap for cleaning my pizza oven stone?

Unlike your regular baking trays, the pizza stone is not meant to submerge in hot water for too long because of its porous surface. The stone tends to absorb water and may get cracked when exposed to intense temperature. So, water and soap are a big no!

Step 2: Cleaning the Inside

Once you are done cleaning the pizza stone, move ahead with cleaning the inside of your oven. The outdoor pizza ovens have a blazing hot interior due to the intense high-temperature range, which makes the spills of sauce and cheese burnt down instead of sticking to the cooking chamber. Regular cleaning is essential to keep the performance of your oven as effective as it was in its first use.

Tools Required to Clean Inside of the Outdoor Pizza Oven

The cleaning of the interior part of the oven might take some time, but the process can be smooth if you have the right tools with you. These tools are recommended to have before starting the cleaning process.

Ash Rake

This particular ash rake is built of stainless steel that prevents rusting or cracks. It has a 25.2-inch-long heat-resistant handle that provides a firm grip and safety.

Once you get your hands on these tools, follow the next steps

Collect the Ash

Since wood-fired pizza ovens operate at extremely high temperatures, the intense heat burns spilled or food bits from the oven and form soot. The high temperatures burn and evaporate the soot during every baking session. However, what’s left is the ashes!

The ash can hinder the performance and taste of the food, so it is advisable to remove it after every baking session. Follow the steps to collect the ash.

  • Wait for the oven to come back to normal temperature.
  • Using an ash rake or shovel, collect the ash that accumulates at the base of the oven and dispose of it in the ashcan.

Scrape off the Interior

At this stage, most of the spills and drips have dried out from the intense heat. It will now be easy to scrap off the walls and base of the oven. You only need to scrape off the debris.

  • Use an Ooni pizza brush or any scraper to scrape off the remaining dried-out food.
  • Don’t use any sharp knife as it may damage the cooking area.
  • Again, with the help of a shovel, collect the remaining filth in the ashcan for later disposal.

Step 3: Cleaning the Exterior

Cleaning the exterior depends on the outside material of the oven. Usually, a brick ovens don’t get dirty and are resistant to rust. They do not require special care, just dust them off with a brush and they are all squeaky clean. However, if the exterior of the oven is made from stainless steel, you have to save some time for outside cleaning.

Stainless steel tends to show up fingerprints and even the finest dirt particles. You can use a damp cloth to wipe off the dirt. If the outer body gets stains or greasy marks, you can also use non-caustic cleaners.

After cleaning, make sure the door of the oven is shut down properly to avoid water leaking into the oven from rain. It is recommended to cover up the oven with a pizza oven cover. This will protect your oven from sun rays and even rain.

It is recommended to use microfiber cleaning wipes to wipe away the dirt and to give the extra shine finish for a sleek and shiny-looking body. The founder of Gozney recommends using a Bar Keepers Friend Power Spray that will effortlessly remove the stains and also gives shine.

Step 4: Cleaning the Chimney

With frequent baking, the chimney of the pizza oven tends to accumulate soot and get dirty. This soot needs to be cleaned after a certain time period to avoid building up and end up causing a fire and damage. The idle way is to brush off the soot with a pizza brush.

The cleaning of the chimney can be influenced by how frequently you bake pizza in the oven.  The pizza ovens that are always in operation with a high production ratio may need to be cleaned more regularly than those that are not used quite often. Don’t use any cleaner or soap as it may damage the inside of the chimney. If the chimney gets blocked with soot, smoke will not properly ventilate and your pizza will end up tasting smoky and burnt.
