Your Griddle Is the Most Unprotected Thing in Your Backyard -- Here's the Fix

Flat top griddles are everywhere right now. Blackstone, Camp Chef, Pit Boss -- if you've been on any outdoor cooking forum, YouTube channel, or backyard cookout in the last two years, you've seen them. And for good reason. A griddle lets you cook breakfast, smash burgers, stir fry, and seafood on the same surface. It's the most versatile piece of outdoor cooking equipment you can own.

But there's a dirty little secret griddle owners figure out the hard way: these things rust faster than almost any other grill you've ever owned. And the usual advice -- season it more, oil it after every cook, buy a better cover -- only gets you so far.

Griddles Are Booming, and So Is the Rust Problem

The flat top griddle market hit $1.5 billion in 2025 and is projected to nearly double to $2.8 billion by 2033, growing at 8% per year. Blackstone alone commands roughly 80% of the residential griddle market. Weber's own product experts called griddles "one of the fastest growing trends" heading into 2026.

That growth is creating millions of new griddle owners -- and millions of new rust problems. Spend five minutes on the Blackstone subreddit and you'll find post after post: "My griddle keeps rusting no matter what I do." "I oil it after every cook and it still corrodes." "I stripped it to bare metal and reseasoned three times this year."

This isn't user error. It's the nature of the beast.

Why Griddles Rust Worse Than Traditional Grills

A traditional grill has porcelain-coated or powder-coated exterior surfaces that act as a barrier between the steel and the elements. A griddle's cooking surface, on the other hand, is raw rolled steel or cold-rolled steel -- bare metal by design. That's what makes it great for cooking. It's also what makes it a rust magnet.

The cooking surface gets all the attention when people talk about seasoning and maintenance. But here's what most griddle owners overlook entirely: the exterior of your griddle -- the frame, the legs, the cabinet, the grease management system -- is just as vulnerable to the elements as any other grill. Often more so, because griddle owners focus all their maintenance energy on the flat top and forget that the rest of the unit is sitting outside in rain, humidity, and temperature swings with minimal protection.

That Blackstone cover you bought? It traps moisture. Multiple owners report mildew forming on the underside of their covers, creating a humid environment that actually accelerates corrosion on the frame and cabinet. A cover keeps the rain off the top, but it can make the moisture problem worse underneath.

The Part Nobody Talks About: Exterior Corrosion

Scroll through any griddle forum and the conversation is always about the cooking surface. Season it. Oil it. Strip it and start over. But nobody's talking about the powder coat on the frame chipping away. Nobody mentions the rust forming on the grease trap housing or the legs. Nobody addresses the cabinet panels that are fading, peeling, and corroding because they're exposed to UV, rain, and grease splatter with zero protection.

This is how a $350-$600 griddle starts looking like junk after 18 months. The flat top might be fine. The rest of the unit is falling apart because the exterior was never protected beyond the factory finish -- and factory finishes on outdoor cooking equipment are designed to look good in the store, not survive years of weather.

Protect the Whole Unit, Not Just the Cooking Surface

Seasoning handles the flat top. A cover handles direct rain. But the exterior frame, cabinet, and components need their own layer of defense -- something that bonds to the metal, repels the grease that splashes down during every cook, and blocks moisture from getting a foothold in every seam and scratch.

That's exactly what Grillacoat was built for. It's a ceramic protective coating you wipe onto the exterior surfaces of any grill, smoker, or griddle in about 10 minutes. It bonds to the metal and creates a barrier that repels grease, resists moisture, and holds up against UV and temperature extremes -- the exact combination of forces that destroy griddle exteriors. One application lasts multiple years. No reapplication every spring. No watching your investment slowly corrode from the outside in.

Think about it this way: you already season your cooking surface after every single cook to prevent rust. Why would you leave the rest of the unit -- the frame, legs, cabinet, and lid -- completely unprotected?

The Smart Play for New Griddle Owners

If you just bought a griddle -- or you're about to -- here's the move: season the cooking surface on day one like everyone tells you to. Then do what almost nobody tells you to do. Protect the exterior.

Apply a ceramic coating to the frame, legs, cabinet, lid, and any exterior metal surface before the first rainstorm, the first grease splatter, or the first humid night. The factory finish won't hold up on its own. A purpose-built protective layer will.

You're spending $400, $500, maybe $700 on a griddle because you want to cook better food outdoors. Spending ten minutes and $119 on a coating that keeps the whole unit looking and performing like new isn't an upsell -- it's common sense.

Your flat top gets seasoned. Your exterior deserves the same treatment. See how Grillacoat works -- 10 minutes, free shipping, 30-day money-back guarantee.
