From natural cleaning to home remedies, onions can help you solve everyday problems in clever, affordable ways. Whether you’re looking to freshen up your space or tackle small annoyances, onions might just be your new secret weapon.

1. Natural Air Purifier – Slice an onion and place it in a bowl of water to absorb unpleasant odors in a room. It’s an old-school trick that helps remove lingering smells from paint, smoke, or even strong food aromas.
2. Soothing Bug Bites – Rubbing a slice of raw onion on a mosquito or insect bite can help reduce itching and swelling thanks to its anti-inflammatory properties.
3. Clean Burnt Pots – Boil a chopped onion in a scorched pot to help loosen up stuck-on food. The acid in the onion helps lift the grime without harsh chemicals.

4. Polish Metal – Onion juice mixed with a little water can bring shine back to rusty or tarnished metals.
5. Hair Growth Booster – Onion juice is rich in sulfur, which can stimulate hair growth when massaged into the scalp regularly.
6. Remove Rust from Knives – Rub a raw onion directly on rusty blades to help break down the corrosion.
7. Keep Avocados Fresh – Storing a cut avocado with a slice of onion can slow browning due to the onion’s sulfur compounds.
8. Natural Moth Repellent – Placing sliced onions in cloth pouches near your closet can help keep moths and insects away.
