Here’s a great trick for oiling your hot grill while cleaning it simultaneously.
1. Take a skin-on onion and cut it in half.
2. Stick a fork into the onion.
3. Dip the open end of the onion into high heat oil (grapeseed, canola, etc).
4. Use the onion as a scraper to clean and oil your grill.
5. Discard the onion.
