How to Clean Sheet Pans and Lift Baked-On Grease

To clean sheet pans, scrape off loose debris, then spread a thick paste of baking soda and a little dish soap over the baked-on grease. Let it sit 20 to 30 minutes, scrub with a non-scratch pad, and rinse. For stubborn stains, add a splash of hydrogen peroxide to the paste and repeat. Dry immediately to prevent rust spots.

What you'll need

Baking soda (about half a cup per pan)
Liquid dish soap
3% hydrogen peroxide (optional, for tough stains)
A non-scratch scrub pad or nylon brush
A plastic bench scraper or old silicone spatula
A microfiber or dish towel for drying
Rubber gloves if your hands are sensitive to soap

Step by step

Scrape first. Use the plastic scraper or spatula to push off crumbs, char, and loose grease into the trash. Doing this dry means less gunk clogging your small sink.
Wet the pan and pour off the excess. You want the surface damp, not flooded.
Mix a paste. Combine baking soda with a few drops of dish soap until it holds together like wet sand. Spread it thickly over every greasy patch, especially the corners where residue builds up.
Wait. Give it 20 to 30 minutes. In a cramped kitchen, park the pan on the stovetop or a folded towel so it's out of your way.
Scrub with the non-scratch pad, working in small circles. The baking soda acts as a gentle abrasive that lifts grease without gouging the metal.
Hit the holdouts. For dark, baked-on rings that won't budge, sprinkle fresh baking soda, add a splash of hydrogen peroxide, let it sit another 15 minutes, then scrub again.
Rinse thoroughly under warm water until no paste remains.
Dry the pan completely with a towel right away. Air-drying in a rack invites rust and water spots, especially on aluminum and carbon steel.

What NOT to do

Don't reach for steel wool or a green scouring pad on nonstick or anodized aluminum pans—they leave scratches that trap food and shorten the pan's life. Skip oven cleaner and other harsh caustics in a NYC apartment with a window that barely opens; the fumes have nowhere to go. Never put warped aluminum or nonstick sheet pans through a hot dishwasher cycle unless the maker says it's safe; the detergent and heat dull and pit the surface. And don't soak carbon steel or cast-aluminum pans overnight—prolonged water contact is exactly what causes rust.

When to call a pro

DIY handles the sheet pans, but a full kitchen deep clean is a different job. If grease has crept up the backsplash, coated the range hood filter, or settled behind the stove where a rental kitchen never gets touched, that's hours of work in a tight space you may not have the storage or the day off to tackle. When you'd rather hand off the whole kitchen instead of one pan at a time, book apartment cleaning with CleanWhale.

FAQ

How do I get baked-on grease off a sheet pan without scrubbing forever?

Let the work happen before you do. A thick baking soda paste sitting for 20 to 30 minutes loosens most baked-on grease, so the final scrub takes seconds instead of minutes. For the worst spots, a second round with hydrogen peroxide added does more than muscle ever will.

Can I use vinegar to clean sheet pans?

A vinegar rinse can help cut light grease film, but don't mix it into a baking soda paste—they neutralize each other and you lose the scrubbing power. Use the baking soda paste first, and if you want, follow with a plain vinegar-and-water wipe afterward.

How do I remove rust spots from a sheet pan?

Make a baking soda paste, let it sit on the rust for 15 minutes, then scrub with a non-scratch pad. Rinse, dry immediately, and going forward, always towel-dry the pan rather than letting it air-dry in the rack.

Why do my sheet pans turn dark and discolored?

That brown or rainbow tint on aluminum pans is oxidation and baked-on oil, not dirt. It's cosmetic and won't hurt your food. You can lighten it with the baking soda method, but on older pans some discoloration is permanent and totally fine to cook on.
