Use onions to keep avocados from browning
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 favourite 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.”

Soothe a bee sting
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 soothe the pain. 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.

Keep frost off your windows
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. Evidently, the sugar found in the onion juice will create a barrier between your car and the water condensation in the air. The sugar also helps break down the ice molecules more easily, making it doubly helpful.

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?

Don’t have any fresh onions sitting around? Getting rust and tarnish off flatware is also one of the many genius hacks for aluminum foil.
Make a natural pesticide
Onions can be useful in both your home and garden. Whip up an effective insect and animal repellent for the flowers and vegetables in your garden and houseplants. In a blender, puree four onions, two cloves of garlic, two tablespoons of cayenne pepper, and one litre water. Set the mixture aside. Now dilute two tablespoons soap flakes in two gallons (7.5 litres) water. Pour in the contents of your blender, shake or stir well, and you have a potent, environment-friendly solution to spray on your plants.

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.
