My mom taught me this trick to keep the barbecue grill spotless in just 2 minutes with zero effort. Here's how to do it

3. Scrub if Necessary:
While the hot grill and onion should handle most of the cleaning, you might occasionally need to scrub stubborn spots. Use a grill brush designed for the purpose to scrub off any remaining residue.
4. Wipe Down:
After cleaning with the onion, switch the grill off and allow it to cool slightly. Then, take a damp cloth and wipe down the grates thoroughly to remove any residual particles or onion juice.
5. Oil the Grates:
For added protection and to ensure an easier clean next time, lightly coat the cooled grates with a bit of vegetable oil.
