So far so good!

So far so good!! Only made smash burgers so far and 1st try wasn't too bad! A little confusing as one place it says no need to season it but in instructions, it says for best results, here's how you season it.

Rust Layer Under Factory Coating

The provided instructions provided with griddle accessory #6789 recommends seasoning your new griddle 7 times before using (even though it is sold "pre-seasoned". Following the directions exactly, after several cycles of the seasoning process, I noticed there were several areas on the griddle surface that were much darker in color and my applied canola oil was not evaporating at the same rate as the rest of the surface areas. After vigorously rubbing this areas, I found that there was rust under the factory applied seasoning. It appears to be that the factory that manufactured these for Weber applied their coating over rusted metal. Very disappointing given Webers history of quality products.

Top Quality, Heavy Duty Cast Iron, Easy Cleanup

Adding the Weber Rust-Resistant Griddle Insert to the Searwood XL 600 give you tremendous grilling/outdoor cooking flexibility. The griddle has an easy set of break-in instructions (be sure to do the break-in to ensure long-life and proper cooking surface). Once complete the griddle is a large, smooth, cast-iron cooking surface perfect for smash-burgers, pancakes, over-easy eggs, sausage, fish, fried rice, and so much more. It really opens up the potential of the Searwood grill. Plus, it cleans up quickly and easily. The size of the griddle allows you to keep one medium sized grill on the XL 600, so you can still add a few steaks, potatoes, or other "standard" smoker/grill items to your cook. The griddle is a great addition to the Searwood.

Question:
can it be used on other grills? Blaze?Was This Helpful?
Answers:

HI Lynn. No, the Weber griddle is designed to replace the grates on Weber grills. For Blaze grills we would suggest the Blaze drop on stainless steel griddle, like this one for 32-inch and larger Blaze grills: https://www.bbqguys.com/blaze/24-inch-griddle-plate-blz-24-ssgp

When will my item arrive?

Once shipped, items usually arrive within 3-5 business days. While UPS and FedEx are our carriers for smaller items, be aware that larger items and orders are shipped via freight. The freight process is a bit more complicated than what we've all come to expect for small parcels, so it's important that you're prepared and understand what's required of you well before delivery day.

  • Most freight products ship on a pallet
  • Some carriers will call to schedule a delivery window, while others will deliver the shipment to a reasonably accessible location closest to your residence (their goal is to deliver as near a garage door as they can).
  • We'll specify which process you can expect in your shipping confirmation email.

For carriers that schedule delivery appointments:

Carriers that schedule delivery appointments require you to be home for delivery and provide your signature. The delivery is made with a semi-truck with lift gate services, and the shipment is dropped off at the curb. If you authorize the shipping company to leave the delivery without a signature, BBQGuys can't be held responsible for damages that occur during delivery. As complicated as this process may seem, we've only scratched the surface here — please review our detailed guide to freight delivery so there are no surprises when a freight shipment heads your way.

For carriers that deliver without an appointment:

Carriers that deliver without an appointment don't require you to be home or set up a delivery window, and you aren't required to sign for the pallet(s). Instead of scheduling an appointment, arranging your schedule to be home for the delivery, and signing to confirm receipt, you can sit back and let your items come to you. If you're home at the time of the drop-off, you can request the driver place your delivery in the garage; if you're out of the house, the driver will leave it near the garage or doorstep.

30-Day Returns
