While it can be tempting to purchase an affordable grill grate, it can have cheap porcelain coatings which can cause a lot of problems down the road. If you have a porcelain-coated grill grate, make sure that you do not use hard metal scrapers and tools when using and cleaning it. This is a simple step that can help prolong the life of your grill grate.
