Make Your Grill Non Stick Using an Onion! Simply heat up your grill and then rub the cut side of an onion over the grate! Not sure if this makes your food taste like onion. I myself LOVE onions, so that wouldn't be an issue for me.
If you don’t grill very often that probably means you don’t clean your grill regularly either. If your grill grates are covered in burnt food and rust, you can get it ready for a cookout with a few household staples.
