How to Clean a Pizza Steel Without Ruining the Seasoning

Written by the Doppio Living team, home baking enthusiasts who've been firing up pizza in our own wood-fired oven for over 10 years. We've cleaned our own steels hundreds of times and dealt with burnt cheese, rust spots, and re-seasoning firsthand.

You just pulled an incredible pizza off your steel. Now you're staring at burnt cheese and flour residue, wondering if you're about to undo all that seasoning.

You're probably overthinking it. Pizza steels are carbon steel, not stainless. Same care rules as cast iron. Whether you call it a pizza steel or a baking steel, the pizza steel cleaning and baking steel cleaning routine is identical.

This guide covers the quick wipe after every bake, burnt cheese and rust removal, the soap debate, and basic pizza steel care. Here's how to clean pizza steel without stressing about it.

TL;DR (How to Clean Pizza Steels)

• Let it cool first. Give your pizza steel 15 to 20 minutes before you touch it. Splashing water on a 500°F steel won't clean it anyway because of the Leidenfrost effect, where the water just dances on a vapor layer and never contacts the surface.
• Scrape while warm. Use a bench scraper or metal spatula to push off burnt food while the steel is still warm to the touch. This takes about 30 seconds.
• Wipe it down. A dry paper towel or old cloth handles the rest. For anything stuck, use hot water and a stiff brush.
• Skip the soap most of the time. Modern dish soap like Dawn won't destroy your seasoning because it physically can't break the cross-linked polymer bonds. But you don't need it for everyday cleaning. Hot water and a brush do the job.
• Use a coarse salt scrub for burnt cheese. Sprinkle kosher salt on the steel, add a few drops of oil, and scrub with a folded paper towel. Salt is softer than both the steel and its seasoning, so it knocks off food without scratching either one.
• Treat light rust with a 50/50 vinegar and water solution. White vinegar dissolves iron oxide, but don't leave it on longer than 15 to 20 minutes. Vinegar attacks good steel too if it sits too long. Rinse, neutralize with baking soda and water, dry immediately, and re-oil.
• Oil after every single cleaning. A thin coat of canola or grapeseed oil, wiped almost completely off with a clean paper towel. Bare carbon steel can start flash-rusting within minutes in a humid kitchen.
• Dark, blotchy color is normal. That's what a well-seasoned steel looks like. If your steel is still shiny and silver after a year of use, something has gone wrong.
• If you're buying a new pizza steel and want to skip the initial seasoning hassle, look for one that comes pre-seasoned. Doppio Living's Chef-Grade Pizza Steel ($99.97 on Amazon, pre-seasoned with organic flaxseed oil, Made in USA) is ready to use out of the box, so your cleaning routine starts from day one.
• Rust is fixable, not fatal. Iron oxide isn't toxic. It's actually FDA-approved as a food coloring. The real issue is that rust means your seasoning has failed in that spot, and the fix is to scrub, re-oil, and re-season.

What Is the Best Way to Clean a Pizza Steel?

The best way to clean a pizza steel after a normal bake is a three-step routine that takes less than two minutes. Scrape, wipe, oil. That's the whole thing. And if you're wondering how to clean baking steel specifically, the answer is identical. Same material, same process.

1. Let It Cool Down

• Wait 15 to 20 minutes after pulling the steel from the oven
• You want it warm enough for food to release easily, but cool enough to handle safely
• Never splash cold water on a hot steel. Thermal shock can warp it, and the water won't even work

Why doesn't water work on a hot steel? Above about 350°F to 430°F, water just bounces around on a layer of steam without ever touching the surface. That's the Leidenfrost effect. Let it cool first, then clean.

2. Scrape the Surface

• Grab a bench scraper or sturdy metal spatula
• Push it across the surface in long, firm strokes
• Knock off any burnt flour, stuck cheese, or charred semolina
• This single step does 90% of the cleaning work

We've landed in the same place after years of cleaning our own steels: the scrape is all you really need. Whatever's left behind will carbonize into harmless ash the next time you preheat to 500°F. America's Test Kitchen backs this up, recommending a "don't do much" approach where remaining residue burns off during the next preheat.

3. Wipe and Oil

• Wipe the surface with a dry paper towel or old rag
• For stubborn spots, dampen the towel with hot water and wipe again
• Apply a thin coat of oil (canola or grapeseed both work great)
• Spread it across the entire surface, then wipe off the excess with a clean dry towel

You want a micro-thin layer, not a visible coating. If you can see the oil sitting on the surface, you used too much. Wipe it thinner. A thick layer won't polymerize properly and will go sticky or rancid during storage.

4. Dry Completely

• Towel-dry the steel immediately after any contact with water
• Then put it back in the oven at 200°F for 10 to 15 minutes, or set it on a low stovetop burner
• Air drying is not enough for carbon steel

This is the most critical step, and the one most people skip. Carbon steel has zero corrosion resistance on its own. Bare A36 steel can start flash-rusting within minutes of getting wet, especially in humid kitchens. Baking Steel's official care guide recommends the oven-drying step after every wash, and it's good advice.

How to Get Burnt Cheese Off Pizza Steel

We've scrubbed burnt mozzarella off our own steels 50+ times over the years, usually from dough that ripped on the launch, sometimes from a topping slide.

We've had a high-hydration dough rip on us during launch, and the cheese and sauce fused to the steel. That's not an exaggeration. At pizza temperatures, cheese gets welded onto the metal.

We've tested pretty much every method you'll see online. Here are three methods that work, in order from gentlest to most aggressive.

1. The Salt Scrub

This is the go-to method and usually the only one you need. Sprinkle a generous handful of coarse kosher salt across the burnt area. Add a few drops of neutral oil (canola works great). Fold a paper towel into a thick pad and scrub in firm circular motions.

It's hard enough to knock off carbonized food but too soft to scratch the seasoning. Then it dissolves in water during rinsing, leaving nothing behind.

If you've never tried it, the salt scrub feels almost too simple. But it handles most burnt-on cheese without touching your seasoning at all.

2. The Reheat and Scrape Trick

If the salt scrub doesn't fully cut it, put the steel back in the oven at 500°F for about 20 minutes. This pushes any remaining food residue into full carbonization, turning it from a sticky mess into brittle ash that scrapes right off with a bench scraper.

Some people run their oven's self-clean cycle to do this more aggressively. It works, but be warned: self-clean hits 800 to 1,000°F, which will destroy your entire seasoning layer along with the burnt food. You'll need to re-season from scratch after a self-clean cycle. Think of it as a nuclear option for truly desperate situations.

3. Chain Mail Scrubber

For stubborn spots that survive both the salt scrub and the reheat, a stainless steel chain mail scrubber provides targeted mechanical force without heavy damage to the underlying seasoning.

Chain mail flexes around surface features instead of gouging flat across them, which makes it gentler than steel wool for this specific job.

NerdChef explicitly recommends steel wool for their pizza steels, while Baking Steel warns against it and sells pumice cleaning bricks as an alternative. Both approaches work. The difference is how aggressive you want to be. If you reach for steel wool or a cleaning brick, plan on touching up the seasoning in that area afterward.

Preventing the mess in the first place. Most catastrophic sticking happens because of upstream problems with dough management or launching technique. If you're fighting burnt cheese every time, check your launch routine.

Using a well-floured peel with enough semolina, working quickly once the dough is on the peel, and making sure your dough isn't overhydrated for your skill level will prevent most cleaning nightmares before they start.

Can You Use Dish Soap on a Pizza Steel

Yes, you can use dish soap (like Dawn) on a pizza steel. Modern dish soap will not destroy a properly seasoned pizza steel. But the answer comes with context that's worth understanding.

Why "Never Use Soap" Was Once Good Advice

The no-soap rule goes back to when household soap was made with lye. Lye (sodium hydroxide) is strongly alkaline with a pH of 12 to 14.

It breaks fat molecules apart through a process called saponification, and it absolutely can dissolve polymerized seasoning. That's not a myth. Lye baths are still used today by cast iron collectors to strip seasoning off antique pans on purpose.

Homemade lye soap was the standard until roughly the 1930s, when synthetic detergents started replacing it. So your grandmother's advice about never using soap was correct for the soap she actually used. It just doesn't apply to the bottle of Dawn sitting on your counter.

Why Modern Dish Soap Is Different

Modern dish detergents like Dawn work through surfactant action, not saponification. Surfactant molecules have a water-loving end and a grease-loving end. They surround loose grease particles and lift them away, but they can't break cross-linked polymer bonds. That's the key distinction.

Seasoning isn't oil. It's a cross-linked polymer that formed when oil was heated past its smoke point and the fatty acid chains broke apart and reassembled into a new material bonded to the metal. Think of it like the plastic in a Tupperware container. Dish soap cleans the inside of your Tupperware without dissolving the container itself, and the same principle applies to seasoning on steel.

As food scientist Sean O'Keefe at Virginia Tech explained in 2024, washing with soap won't remove the protective polymerized layer because that layer is no longer oil. Lodge Cast Iron, the most recognized manufacturer in the space, officially recommends using a small amount of soap. So does Baking Steel on their care page.

When to Skip and Not to Skip Soap in Cleaning Your Pizza Steel

If you're cleaning up after a normal pizza night, skip the soap. Hot water and a stiff brush handle it. If you've got a greasy steel that really needs degreasing, a small amount of Dawn is perfectly fine. Just dry the steel immediately and re-oil it. The re-oiling step after soap is the important part, because you've removed that protective surface oil layer.

If you're nervous about soap and want to avoid the debate entirely, the hot water and bench scraper routine is all you need for 95% of cleaning jobs.

How to Remove Rust from a Pizza Steel

Removing rust from a pizza steel starts with one important fact: rust on carbon steel is normal, fixable, and not dangerous. Iron oxide (the chemical name for rust) is FDA-approved as a food coloring (listed as E172).

You don't want it on your food because it tastes metallic and stains things, but it's not a health hazard. If you searched "how to remove rust from pizza steel" expecting bad news, you can relax.

We've had that exact panic ourselves, seeing rust on a steel we'd taken care of and feeling like we'd broken something expensive. The answer is always the same: scrub it off, re-season, and move on. Here's how, depending on what you're dealing with.

For Light Surface Rust: The Vinegar Method

• Mix a 50/50 solution of white distilled vinegar (5% acetic acid) and water
• Dampen a cloth with the solution and lay it over the rusted spots
• Let it sit for 15 to 20 minutes, no longer
• Wipe and scrub with a stiff brush
• Rinse thoroughly with clean water
• Neutralize the acid by wiping with a baking soda and water solution
• Dry immediately (towels, then 200°F oven for 10-15 minutes)
• Oil the surface right away (bare metal flash rusts within minutes)

Important: vinegar attacks good steel too, not just rust. If you see tiny bubbles forming, that's hydrogen gas from acid reacting with bare iron. Stop and rinse immediately.

For Heavy Rust: Full Scrub and Re-Season

• Scrub the rusted area with steel wool, a pumice cleaning brick, or fine sandpaper until you're back to clean grey metal
• Wash the entire affected area with hot soapy water (this is one of the times soap is actually useful)
• Dry the steel thoroughly and immediately
• Apply a micro-thin coat of oil, wipe off the excess
• Bake at 400°F for 1 hour
• Let it cool completely inside the oven
• For severe cases, repeat 2-3 times

Our pizza steel care guide walks through the full re-seasoning process in more detail.

For Dull or Slightly Oxidized Steel (Not Full Rust)

• Wipe on a fresh oil coat with a paper towel
• Heat in a 400°F oven for 30 minutes
• Let it cool in the oven

This brings most steels back without needing a full re-seasoning.

Tips on Cleaning a Pizza Steel from Experienced Home Cooks

Here are the cleaning hacks we've picked up over 10+ years of running our own steels, through plenty of trial and error in our home kitchen.

1. The "Ugly Steel Is a Good Steel" Mindset

When our first steel started turning dark, blotchy, and uneven, we thought we were doing something wrong. Now we know that mottled, blackened look is exactly what you want.

These days we barely clean ours beyond scraping off stuck bits. The steel looks rough, but it cooks beautifully. If your steel still looks silver and pristine after months of use, your seasoning hasn't built up enough.

2. The Parchment Paper Hack (With a Warning)

Using parchment paper on the peel under the dough completely changed our launching routine when we first tried it. No more stuck dough, no more messy cleanup, no more stressful launches.

It works. But there's a serious catch we learned the hard way: parchment paper will catch fire under a broiler.

If you use the broiler to brown the top of your pizza (and most steel users do), keep the parchment paper away from the edges and watch it closely. Or pull the parchment out from under the pizza after the first minute or two, once the crust has set.

3. Avoid Avocado Oil for Seasoning

This one surprised us when we first tested it. Avocado oil is marketed as a premium high-heat oil, so we tried seasoning a steel with it. The high smoke point that makes avocado oil great for cooking actually works against it for seasoning.

Our home oven couldn't get hot enough to push avocado oil past its smoke point and trigger polymerization. The result was a sticky, gummy layer that never properly cured and made food stick worse.

We've had far better luck with canola, grapeseed, or even plain vegetable oil. They polymerize properly at normal oven temperatures and build a smooth, durable coating.

4. Wipe Off More Oil Than You Think

The single biggest seasoning mistake we've made (more than once) is using too much oil. You apply a thin coat and think you've got it right, but you haven't wiped enough off. The rule we follow now is to wipe until it looks like there's no oil left at all. The microscopic layer that stays in the pores is all you need.

Too much oil creates two problems we've seen firsthand: a gummy, sticky surface that attracts dust and makes food stick, and a smell during heating that we can only describe as burnt fish throughout the whole house. That smell is excess flaxseed or other polyunsaturated oil smoking off in a thick layer.

5. Prevent the Mess Before It Happens

The best cleaning tip we can share has nothing to do with cleaning. It's about your launch technique. Most of the welded-on cheese disasters we've dealt with happened because the dough ripped on the way onto the steel, usually from too much hydration for our skill level at the time.

If you're fighting major cleanup every time you bake, the fix isn't a better scraper. It's dusting your peel properly with semolina, working quickly once the dough is stretched, and keeping your hydration at a level you can actually handle. For more on dialing in your technique, our first-time pizza steel guide covers the fundamentals.

6. The Dishwasher Is the Only Real Way to "Ruin" a Steel

The only real way we've seen a steel get "ruined" is the dishwasher. The alkaline detergent strips the seasoning, the water exposure causes full-surface rust, and the result looks catastrophic.

But even then, the steel itself is fine. It's a solid slab of industrial metal. A full scrub, re-seasoning, and a few bakes later, it's back to normal. The lesson we've learned after years of this: tell your household that the steel never goes in the dishwasher, and leave it at that.

How We Clean Pizza Steels Fast and Easy

Cleaning a pizza steel really comes down to three things: scrape, wipe, oil. The whole routine takes less than two minutes after most pizza nights, and it's no more complicated than taking care of a cast iron skillet.

For a broader look at ongoing care beyond just cleaning, our complete care guide covers everything from daily maintenance to long-term storage. And if you're still deciding between a pizza steel and a pizza stone, our pizza steel vs stone comparison breaks down the differences in heat transfer, durability, and results.

FAQ

Does White Vinegar Actually Remove Rust from a Pizza Steel?

Yes. White distilled vinegar (5% acetic acid) dissolves iron oxide through a chemical reaction that converts rust into water-soluble iron acetate. For light surface rust, a 50/50 vinegar-water solution applied for 15 to 20 minutes is usually enough. For heavier rust, you can use undiluted vinegar and let it sit longer, but don't exceed a few hours.

Vinegar also reacts with the base steel itself, not just the rust, and prolonged contact can cause pitting. Always neutralize with a baking soda and water rinse afterward, dry immediately, and re-oil.

What Happens If You Use Vinegar on a Carbon Steel Pizza Steel?

Vinegar dissolves rust effectively, but it's not selective. The acetic acid reacts with both iron oxide (rust) and bare iron (your steel). Short exposure of 15 to 20 minutes targets the rust without meaningful damage to the steel itself.

Longer soaks, especially overnight or longer, can etch the metal surface and even cause hydrogen embrittlement, where the steel becomes slightly brittle. If you use vinegar, treat it like medicine: effective in the right dose, harmful in excess. Rinse, neutralize with baking soda, dry completely, and re-season the affected area.

Can You Use Baking Soda to Clean a Pizza Steel?

Baking soda works well as a gentle cleaning paste and as a neutralizer after vinegar treatment. King Arthur Baking recommends mixing baking soda with a small amount of water to form a paste, applying it to stubborn stains, letting it sit, then wiping it away.

Baking soda sits at about 2.5 on the Mohs hardness scale, making it slightly softer than seasoning and safe to use without scratching. It's also mildly alkaline, which helps cut through grease without the surfactant action of soap.
