The benefits porcelain cooking grates offer are easy cleanup, and a rust-free cooking surface. You'll also find that food doesn't stick to the grate to badly. With the benefits comes the need for special care. You just can't treat these like any old cooking grate when it's time to clean up.
The porcelain coating can be bonded to one of two different materials...steel or cast iron.
The grates with a steel core are less expensive. They also retain less heat, so they don't perform as well when high-temperature searing steaks and seafood.
Porcelain coated cast iron grates have the grilling qualities of the cast iron core, with the convenience of the easily cleaned porcelain finish. Although more expensive than the steel core grates, the extra cost is worth it if you like to see those pretty grill marks on your barbecued foods.
The best quality porcelain grates have wide, heavy crossbars with narrow spaces in between. The heavier the inner metal core, the more heat the grate will hold, which translates into better quality grilled foods.
When cleaning porcelain cooking grates special care must be taken. Even though the porcelain is a very hard material, it can be easily damaged if handled incorrectly. The following tips will help you get a long life from the porcelain coating.
Clean your grates after each cookout for the best results.
Before heating up the grill for the next cookout, spray the top surface with a good quality cooking spray, preferably one made for use with grills. Another way to oil the grate is to grip a wad of paper towels in you tongs, dip it in vegetable oil and wipe it on.
Treat your porcelain cooking grates with care and they will provide you with great performance and a long life.
