The Blackstone griddle tops are made of steel and all steel, naturally, wants to rust. In order for rust to occur you need exposure to air and water. This is why if you live in an area with high humidity you will need to be extra vigilant to protect your griddle top from the elements.
Not all rust is going to be preventable but luckily our griddles are very easy to clean and with a few pointers you should be able to prevent most corrosion.
Even in a worst-case scenario, a griddle top with heavy corrosion can be restored by just following a few simple steps.
So, here are the cleaning tools you will need.
- A metal Scraper
- Oil (any cooking oil will do)
- Paper towels
- And a Grill Stone Cleaning Block
First, turn your griddle on to high heat. This will loosen up any rust or debris so it will be easier to remove.
Now use a metal scraper and scrape as much corrosion off as you can. If you don’t have a metal scraper, a metal spatula should work just fine.
Do this step dry. Don’t use any water. Remember, water is one of the major causes of rust and we are going to strip any protective layer from the griddle so introducing water at this stage would be counter productive.
Once you’re done scraping as much as you can, let your griddle cool for a while then brush away all the debris on top.
Now use regular cooking oil and the grill stone to scrub your griddle surface. You’ll typically find the grill stones in the BBQ isle of the store but if you can’t find a grill stone try using steel wool or a medium grit, wet/dry sandpaper.
Now use paper towels to wipe the griddle clean. Apply more oil and wipe the griddle down again. Do this until all of the rust debris is gone. If you missed any spots just go back over them with oil and the grill stone.
Once your griddle top is clean it’s time to season it. Seasoning your griddle top will give it a natural protective coating to help prevent corrosion and give you a nice stick-resistant surface to cook on. There are a lot of oils you can use for your initial seasoning layer and even more arguments about which one is best. We have recommended Flax Oil in the past for your initial seasoning, but it is fairly expensive and though it does create a very nice bond it can also get brittle over time. I’ve used Olive Oil and lately have been testing the Crisbee Puck with pretty good results. In the end, the best thing for your griddle is to use it a lot. The more you cook with it, the better it will be.
Here is a list of oils you can use for your initial seasoning but if you have something else that you prefer go ahead and use it.
- Flax Oil
- Extra Virgin Olive Oil
- Vegetable Oil
- Vegetable Shortening (Crisco)
- Canola Oil
- Coconut Oil
- Crisbee Puck
For this griddle top I actually used California Olive Ranch Extra Virgin Olive Oil.
See our Post on Griddle Seasoning & Care Guide for more detailed instructions on seasoning your griddle.
Apply a small amount of oil to your griddle and spread it around with a rolled-up paper towel or lint-free cloth.
Turn your griddle on to medium-high heat.
You will see the oil start to smoke and the surface of your griddle will start to discolor. This is good. This means the oil is burning off its organic compounds and bonding to the metal.
Keep your griddle on medium-high heat until the oil stops smoking and your griddle surface starts to turn matte gray. This will typically take about 30 minutes.
Turn your griddle off and let it cool.
Repeat Step 4 about 3 or 4 times until you have a fairly even matte black griddle top.
After this initial seasoning, simply cooking on your Blackstone griddle will add to the seasoning layer.
Once you’ve seasoned your griddle you want to store it with a protective layer of oil to create a barrier from air and moisture. Use regular cooking oil for this step and wipe down your griddle top with a thin layer in between uses. Cooking spray works really well for this. Don’t forget to wipe down all of the sides of the griddle top too. Make sure you do this every time you use your griddle. The oil acts as a barrier to air and water.
If you don’t have a cover for your griddle we highly recommend one. It protects your griddle top from rain and dust. I live right next to a large open field and before I got a cover I would have to wipe a layer of dirt off of the griddle every time I used it.
