If you have a nasty encounter with a bee at a barbecue, grab one of the onion slices intended for your burger and place it over the area where you got stung. It will ease the soreness. This trick doesn’t actually treat the sting, only the pain, so if you are severely allergic to bee or other insect stings, be sure to seek medical attention at once.

Ease a burn

Onions aren’t just good for bee stings, they’re also great to grab if you burn yourself. Home remedy experts at The People’s Pharmacy claim that fresh onion juice is the perfect balm for a fresh burn, and will even help prevent blistering. The key word: Fresh. For this hack, you’ll want to grab a whole onion and cut it freshly, because precut slices won’t do the trick. If you don’t have onions lying around.

Fresher avocados? We’re in! TODAY reported that placing a cut onion in the container with your sliced, or otherwise cut, avocado is their all-time favorite method for helping it stay greener longer. “Sulfur dioxide is a compound used to preserve fruits,” TODAY stated. “Sulfur is a component in onions, so it stood to reason it might work similarly. By far, the best of all methods, the avocado was nearly as green as when it was cut.”

Believe it or not, onions can help you winterize your car, too. In a separate report, TODAY demonstrated how you can save time scraping ice off your car on those frigid winter mornings, by simply rubbing an onion on your windshield the night before.

Remove rust from knives

Remove rust from knives

Forget about using steel wool or harsh chemicals—how’s this for an easy way to get the rust off your kitchen or utility knives? Plunge your rusty knife into a large onion three or four times (if it’s very rusty, it may require a few extra stabs). The only tears you shed will be ones of joy over your rust-free blade. Don’t have any fresh onions sitting around?

Clean your grill

Clean your grill

Put a freshly cut chunk of onion on the end of a fork, cut side down, and run it along the grates of the grill. The same components of the onion that give it that sharp taste will help loosen up the grime and food bits left over. The Kitchn suggests heating up the grill first to burn down any large food particles and rubbing with the onion as soon as it has cooled to a manageable temperature.
