How to Deep Clean and Re-Season a Blackstone Griddle

Even with regular cleaning, over time grease, oils and seasoning can build up on the surface of your Blackstone. About once or twice per year, we recommend performing a deep clean and re-seasoning of the griddle surface. Follow these simple steps to keep your Blackstone in great condition.

Equipment

  • metal scraper
  • squeeze bottle
  • Blackstone cleaning brick
  • high heat BBQ gloves
  • metal tongs
  • Paper Towels

Ingredients

  • high smoke point oil such as grapeseed oil
  • Blackstone Seasoning and Cast Iron Conditioner

Instructions

Deep Clean the Surface

  • Turn all of the burners on to heat the entire griddle surface.
  • Use a metal scraper and high heat BBQ gloves to apply pressure to the surface. Work it a little more aggressively than a typical cleaning after cooking, trying to get some of those flaky areas broken up.
  • Then turn the griddle off, and let it cool.
  • Once the surface has cooled down, drizzle on a few tablespoons of a high smoke point oil.

  • Using a cleaning brick, work it in a circular motion in the middle and back and forth along the edges. You don't have to apply extreme pressure. You just want to take off those excessive layers that never really bonded. This should take about 5-7 minutes of working on the surface with the brick.

  • Wipe up the oil from the surface with paper towels. At first, they will be jet black because of all of the seasoning that has just been sanded down.
  • After wiping it up, drizzle on a little more oil, and use that to wipe up more of the sanded out seasoning. Repeat this one or two more times until the oil starts to look cleaner, meaning you've wiped up most of the bits of seasoning you scraped off.

Re-Season the Surface

  • Turn the heat back on, and let the griddle surface get hot. Allow any remaining oil on the cooktop to smoke off.

  • Apply a small amount of Blackstone Griddle Seasoning and Cast Iron Conditioner to the hot surface. It should immediately melt. Spread it around to form a thin layer with paper towels held with metal tongs. Make sure to protect your hands with high heat BBQ gloves.

  • Let it burn on and completely smoke off (until you no longer see smoke) before you turn off the heat.
