How to season a Weber Slate
It arrives pre-seasoned, which changes the job from a seasoning session to a maintenance habit.

Why this is a different job
The Weber Slate ships with a rust-resistant, pre-seasoned carbon-steel cooktop. You can cook on it the day it arrives.
That removes the single biggest barrier for new griddle owners — and it also means that running a full bare-steel seasoning process on it is unnecessary work that mostly adds thickness where thickness is the enemy.
Day one
- Follow Weber’s own first-use guidance for your model. It is typically a wipe and a heat cycle rather than a multi-round seasoning.
- Heat the griddle and wipe it down to remove any transit residue.
- Lay down one very thin oil film while warm, if the guidance calls for it.
- Cook. Something fatty for the first cook is still a good idea — it starts building your own layers on top of the factory surface.
What “rust-resistant” actually changes
It is resistant, not proof. The practical difference is tolerance: forgetting the after-cook oil once, or leaving it uncovered through a damp weekend, will not pit the surface the way it would pit bare carbon steel.
What it does not mean is that the griddle is weatherproof. It still wants a cover, and it still benefits from a thin oil film after cooking — both as protection and because that film keeps building the non-stick character of the surface.
Ongoing routine
Same shape as any griddle, with less consequence for lapses:
- Scrape while the plate is still hot.
- Squirt water to steam-lift residue, scrape again, wipe.
- Thin oil film while warm.
- Cover once cool.
What not to do to a Slate
- Do not strip it with a pumice block or cleaning brick as routine maintenance. On a bare steel top that is a legitimate reset; here you would be abrading a treated surface for no reason.
- Do not use soap routinely. Same rule as any griddle — it strips the layers you are building on top of the factory surface.
- Do not pile on thick oil coats trying to get a blacker finish. Thick coats stay tacky and eventually flake, on this surface as on any other.
If it does rust
Resistant is not proof, and a Slate left uncovered for a long time in a wet climate can still corrode. The recovery is the same as for any steel top — abrade the affected area back, flush the debris out, re-season that area — but be more conservative about how aggressively you abrade, since you are working on a treated surface rather than bare steel. Rust removal.
The picks in detail
Specifications are linked to their source on every card. Scores are ours, derived from those specifications.
#1 · Oil control, which is most of the technique
Squeeze Bottle Set
Two bottles — one oil, one water — are the most underrated griddle tools there are, because dosing oil by eye is how food sticks or swims.

Key specifications
- How many
- Two minimum: oil and water
- Tip
- Narrow, so you can lay a thin line rather than a puddle
- Water bottle use
- Steam-lifting residue and steaming under a dome
- Material
- Heat-tolerant — bottles sit near a hot plate
- Caps
- Must seal; open bottles collect everything
- Label them
- Oil and water look identical in an opaque bottle
Specifications from Blackstone accessories.
Scores
- Control9.0
- Material7.0
- Sealing7.5
- Value9.5
What works
- A thin controlled line of oil is the difference between a seared crust and a fried one
- The water bottle makes daily cleanup a 60-second job
- Trivially cheap for how much technique they unlock
What to know
- Wide-tip bottles over-dose oil and defeat the purpose
- Cheap plastic deforms if left on a hot side shelf
- Oil goes rancid in a bottle left outside for months
#2 · The 60 seconds after every cook
Griddle Scraper
A stiff, flat scraper used while the plate is still hot is the entire daily cleaning routine — everything else is an occasional job.
#ad We publish no prices: there is no verified price feed on this site, so the retailer’s page is the only price. How this is funded
Key specifications
- Blade
- Stiff and dead straight — a curved blade misses the middle
- Width
- Wide enough to clear a lane in one pass
- Handle
- Long enough to stay out of the heat
- When to use
- While the plate is still hot, right after cooking
- Pairs with
- Water, squirted on to steam-lift the residue
- What fails first
- The blade's leading edge, which rounds off
Specifications from Blackstone cleaning accessories.
Scores
- Stiffness9.0
- Edge8.5
- Handle7.5
- Value9.0
What works
- A hot plate releases residue that a cold plate will not — timing matters more than the tool
- One stiff scraper replaces an entire cleaning kit for daily use
- Nothing to wear out but the edge
What to know
- A rounded or flexible blade skates over the fond instead of lifting it
- Short-handled scrapers put your knuckles over a 400 °F plate
- Does not address rust or a flaking seasoning layer
#3 · The single cheapest way to stop rust
Griddle Cover (match your width)
The accessory that decides whether a bare-steel griddle survives its first wet season — buy it sized to your griddle's width, not approximately.
#ad We publish no prices: there is no verified price feed on this site, so the retailer’s page is the only price. How this is funded
Key specifications
- Match on
- Griddle width: 17, 22, 28 or 36 in
- Also match
- Hood vs no hood — a hood changes the height
- Critical feature
- Vents, so trapped moisture can escape
- Critical feature
- Straps or a cinch, or wind lifts it off
- What fails first
- Seams and the elastic hem
- Common mistake
- A cover that fits loosely holds water against the top
Scores
- Fit9.0
- Durability7.0
- Rust protection9.5
- Value9.0
What works
- A vented, correctly sized cover prevents more griddle deaths than any other single purchase
- Cheap relative to the surface it protects
- Works with the hard cover rather than instead of it — the hard cover keeps rain off the plate, the soft cover keeps it off the cart
What to know
- An unvented cover is worse than no cover: it traps condensation against bare steel
- Sizes are not interchangeable between brands even at the same stated width
- Covers are consumables — UV destroys them in a few seasons
