CARE AND MAINTENANCE OF COOKING GRATES
We genuinely care about our consumers and the life of our grills! LP, as liquid propane, is 270 times more compact than it is as a gas, which allows it to be easily transported and stored as a liquid until ready to use. Because it is a liquid, it causes condensation (moisture) in your grill. Moisture is the nemesis of raw metal. This is why it is so important to go through the entire Seasoning Process. Keep in mind, seasoning is not a one-time event but an on-going process.
Your cooking grates are made of cast iron. Folks prefer cast iron because it gets hotter and holds the heat longer than other metals like stainless steel, for example. The truth is, cast iron is corrosive. In order to extend the life of the grates, Char-Griller coats them with a porcelain-coating. Applying porcelain to cast iron enhances the durability of cast iron and provides a layer of protection from the cast iron and any moisture. It also provides easier clean up after use. Porcelain does have a strength to it, however, if cleaning with anything abrasive, it will cause scratches to the porcelain-coating. This will compromise the durability of the porcelain coating and allow moisture to seep through those scratches/cracks and allow cast iron to rust. This will allow rust to form between the layers causing the porcelain to pop off and the grate to rust further. Char-Griller recommends using a nylon brush or better yet, while the grill is still warm, cut an onion in half, place the cut side down, using a meat fork, stab through the top of the onion and use that to clean any debris from the cooking grates. Wire brushes are too abrasive and can cause scratches and cracks in the porcelain that can fill with moisture and cause rusting underneath the coating.
The grates are not naturally non-stick. 100% vegetable oil does not just burn off the grates during seasoning. It creates an enamel over the porcelain and creates a protective barrier between the cast iron and any moisture that would cause the formation of rust. This is also why food particles do not stick to the grates when they have been thoroughly seasoned. Go through the entire seasoning process 3 times. You will see the hard, shiny, enameling begin to build the second time through and by the third time, you’ll know exactly what we are describing!
1. Coat cooking grates, flame shields, interior hood, and body with 100% vegetable oil, olive oil, lard, or animal fat.
2. Heat the grill to 300- 350 degrees and allow to bake for 1 to 1 1/2 hours.
3. Allow the grill to cool down.
4. Once the grill has cooled to the touch, coat again with 100% vegetable oil, olive oil, lard, or animal fat.
5. Heat the grill again to 300-350 degrees for 1 to 1 1/2 hours.
6. Allow grill to completely cool down and oil it all down one last time and go through the process for the third time.
7. After the grill cools, spray the grill one final time with oil and wipe down with a paper towel. It is ready for some serious grilling!
Depending on how often you use the grill will determine how often this needs to be repeated. As you use the grill, keep an eye on that enameling. Eventually, it will begin to deteriorate.
If the rust has begun to build, you may want to try these cleaning alternatives that are more abrasive than a nylon brush, but won't cause damage to your grates.
Vinegar - Rub the rusty surface with plain white vinegar at full strength and allow it to sit for a few minutes. Once the vinegar starts to dissolve the rust, use your nylon brush to begin cleaning the affected area. Repeat until the rust is gone.
Baking Soda Paste - As an alternative to using vinegar, you can attempt to clean rust off porcelain coated cast iron grills and other metal surfaces using a thick paste made from baking soda and water. Apply the paste to the rust build-up and allow it to sit for a few hours. Then, scrub away the paste using a nylon brush, repeating as necessary.
Salt Paste - If you need something stronger than baking soda or vinegar to remove the rust from your cast iron grill, make a thick paste of kosher salt and water. Apply it to the rusty area, then use a nylon brush to scrub away the rust. Repeat as necessary. For particularly stubborn rust, you may need to begin your cleaning efforts with a salt paste but may find that you can switch to the less abrasive baking soda paste once the first few layers of rust have been removed.
