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.
In this video from the HouseholdHacker YouTube channel, you'll find some clever cleaning tricks for around the house, like sprucing up your grill that's seen better days. First, pull off your grill grates and place them on a flat surface that can get a little messy. Then slice up an old potato that's going green into thick pieces that are easy to hold onto, spread vegetable over the grill grates, and sprinkle plenty of coarse salt over them. Now scrub the grates with the potato pieces.
The abrasive combination of the salt and potato will remove all the burnt gunk and rust. And once it's clean, your grill grates will have the perk of being non-stick and ready to cook on too.
