How To Clean a Blackstone Griddle
After you cook, let the Blackstone cool until it is warm, not screaming hot. Scrape food and grease into the grease trap, loosen stuck bits with a small splash of water, wipe dry, and finish with a paper-thin coat of high-smoke-point oil. Use soap only on a brand-new, unseasoned top (or after a full strip). Soap on a seasoned cooktop strips the polymerized oil that makes it nonstick and rust-resistant.
Safety first
- Burns. The steel holds heat. Wear heat-resistant gloves. Hold paper towels with tongs. Water on a hot top turns to steam instantly — keep your face and hands back.
- Grease flare. Do not dump a cup of water onto a pool of hot grease. Use a small amount, or wait until the surface has cooled to warm.
- Outdoors and fuel. Use propane griddles where the maker says they belong, with clear ventilation. Never bring a lit propane griddle into a garage or house. Empty the grease cup before it overflows into the burners.
- No wire-brush bristles on the cooktop. Loose metal in food is the hazard. Use a flat metal scraper, a nylon or palmetto brush, or a pumice grill stone made for griddles.
- Rust starts with water left on bare steel. Dry completely, then oil, every time.
How often
Wash and season a new griddle before the first cook — Blackstone ships a light factory coating that is not the same as a cooking seasoning. After that, a 5-minute scrape-wipe-oil after every use is the whole program. Cover it once it is cool and dry.
What you need
- Metal scraper or stiff spatula
- Paper towels and a microfiber cloth (first clean)
- Heat-resistant gloves and tongs
- Mild dish soap — first time or full strip only
- High-smoke-point oil (see below)
- Pumice grill stone or non-metallic pad, for rust
- Bucket, for the first wash
Which oil for seasoning
Use a thin layer of a high-smoke-point oil: Blackstone’s own seasoning conditioner, avocado, canola, grapeseed, or plain vegetable oil. Heat each coat until it stops smoking so the oil polymerizes instead of sitting gummy.
Skip extra-virgin olive oil and butter for seasoning — they smoke early and can go sticky. Flaxseed oil polymerizes hard, then often flakes on a big steel top that expands and contracts; it is a fussy choice, not a default. Cooking spray leaves propellants and a patchy film — do not season with it.
Blackstone’s own care sheets have listed a wide range of oils over the years, including olive. For a durable first seasoning, stick to the high-smoke-point list and thin coats.
First-time clean (the only soapy wash)
- Mix a gallon or two of warm water with a few drops of mild dish soap.
- Wipe the cold cooktop with a wrung-out cloth. Rinse the cloth often so you lift factory residue instead of spreading it.
- Wipe again with clean water until the soap is gone.
- Dry with paper towels, then let it sit until there is no dampness. Bare steel rusts if you walk away wet.
- Fire the griddle on high about 10–15 minutes until the steel darkens.
- Wearing gloves, spread 2–3 teaspoons of oil over the entire top — including edges — with a paper towel in tongs. It should look barely shiny, not puddled.
- Heat until the smoking stops and the surface darkens more. Repeat the thin-oil-and-burn-off three or four times. Thick coats turn gummy, then flake.
After every cook
- Turn the heat down and wait until you can work over the top without the scraper instantly smoking. Warm residue slides; white-hot residue spatters.
- Scrape food and grease into the trap. Wipe with a paper towel.
- For stuck sugar or cheese, a small splash of water to steam it loose, then scrape. Keep clear of the steam.
- A non-metallic pad is fine for stubborn spots. No soap. No steel wool that sheds.
- Wipe dry. Spread 1–2 teaspoons of oil over the whole top, including corners. Store dry, covered, grease cup emptied.
Rusty top
Surface rust is fixable. You are going back toward bare steel, then seasoning again.
- Heat the griddle (gloves on). Rust scrapes more easily warm.
- Scrape in overlapping passes. Keep the surface dry while you scrape.
- Let it cool enough to handle, wipe off powdery rust, then scour with a few teaspoons of oil and a pumice stone until a paper towel comes away without orange.
- Re-season with the same four thin coats as a new griddle.
- Store dry with a cover. Rain and a wet lid are how rust returns.
Vinegar, salt, and dish soap
Vinegar is for a restoration, not Tuesday night. Acid strips seasoning and, left on steel, invites rust. If you use a little to cut stubborn film, rinse, dry at once, and re-season the same day.
Salt: Blackstone’s own method uses about ¼ cup of table salt as a mild abrasive after a splash of hot water. Buff, scrape the paste into the trap, wipe, oil. Good between fish and pancakes.
Dawn or other dish soap: first cleaning only, or after you have already decided to strip the seasoning. If you soap a seasoned top, you have not ruined the griddle — you have just given yourself a re-seasoning job.
If seasoning is sticky or flaking
Sticky almost always means too much oil or not enough heat. Run the griddle hot until it stops smoking, scrape, wipe, and apply a much thinner coat. Black flakes are usually carbonized oil, not Teflon — scrape them, oil thin, cook on.
The routine that lasts
Everyday: scraper, a little water, dry, thin oil. Odors: salt buff. Rust: stone, then full re-season. Keep it covered and dry and a Blackstone cooktop lasts years. If the rest of the outdoor kitchen is the mess — patio, stainless, the kitchen you carried dinner through — Pro Housekeepers can handle the house while you keep the steel oiled.
FAQ
Can I use soap after I have cooked on it?
You can, but you will strip seasoning and need to build it back. For daily cleaning, water and a scraper are enough.
Why is my food still sticking?
The top is under-seasoned, too cool when food went on, or coated in leftover sugar. Heat, a thin oil film, and a clean scrape fix most of it.
Do I oil it for storage in summer humidity?
Yes. A thin coat every time, plus a cover on a dry top, is the rust insurance.
