Seasoning is the first step towards a long-lasting, rust-free Blackstone griddle. All you have to do is coat a griddle surface with a thin layer of oil and turn it on high for at least 20 minutes. Then starts the cycle of burning and readying the griddle for its first sear. Repeat this five times.

Taking precautions to keep your Blackstone griddle rust-free increases its lifespan. As they say, it’s better to be safe than sorry. Mold and rust develop on the Blackstone when it is not cleaned after every use and if moisture is allowed to sit on it for a long time without any coverage.

It also entails reseasoning of the Blackstone, which increases the lifespan of the griddle. Mold appears on a Blackstone for similar reasons and needs to be cooked off, wiped with paper towels, oiled and ready to cook your favorite steak dinner.

3. Scrape and Clean Your Blackstone Regularly:
Along with reseasoning, remember to scrape and thoroughly clean the Blackstone griddle for its long-lasting usage.

On those occasions, when rust finds its way on your beloved griddle, follow the below mentioned rust removal methods to restore Blackstone griddle.
1. Efficiently Remove Corrosion from Blackstone Griddle
Remember to wear your heat-resistant gloves, heat up the griddle to medium heat and let it heat up for 20 minutes so any rust and residue loosens up.
Turn off the heat and let the Blackstone cool down. Get your wide metal scrapper and scrape off the loose food residue left behind from your last cooking. Get the cooking oil of your choice and put a thin layer on the griddle’s surface, then scrub it off with a handy steel wool surface cleaner.
Wipe off the remaining residue or leftover cleaner with paper towels. If you are facing a rust caked Blackstone griddle, then repeat the above-mentioned steps until all signs of corrosion are removed and you find a charred and clean Blackstone griddle surface.
2. Pressure wash the rust away
Pressure washing is an efficient and ergonomic way to clean your grill as well. It’s easier, effective and cleans even the hard-to-get nooks and crannies of your griddle. Instead of scrubbing for an hour, a pressure wash may clean your Blackstone within 15 minutes.
This is best suited when there is mold on Blackstone griddle. However, it is a dirty task as dirt and grease may fly all over your garage or patio. Also, gas burners may be negatively affected by this method if they remain uncovered.
3. Pumice Stone Grill Brick Scraper:
