Why Do My Hands Smell Like Onions?

The strong onion smell on hands comes from sulfur compounds that are released when you chop or crush an onion. These compounds bond to your skin, making the odor difficult to remove with just soap and water. The same issue happens with garlic, which is why many people also search for why do my hands smell like garlic.
Since onion juice penetrates the skin and lingers for hours or even days, neutralizing the sulfur compounds is the key to eliminating the odor. Let’s explore some of the most effective methods to remove onion smell from hands.

Best Methods to Get Onion Smell Off Hands
1. Stainless Steel: The Most Surprising Trick

One of the easiest and most effective ways to get rid of onion smell on hands is by using stainless steel. The sulfur compounds in onions bond with the steel, neutralizing the odor.
How to use stainless steel:
- Rub your hands against a stainless steel sink, faucet, or spoon under cold running water for 30-60 seconds.
- If you cook with onions regularly, consider buying a stainless steel odor-removing bar, which is designed specifically for removing food odors from hands.
Why it works: Stainless steel binds to the sulfur in onions, lifting it away from your skin. It’s a chemical reaction that neutralizes the smell almost instantly!
2. Lemon Juice: A Natural Deodorizer

Lemon juice is acidic and works to break down onion sulfur compounds, removing the smell from your hands.
How to use lemon juice:
- Cut a lemon in half and rub it directly on your hands.
- Alternatively, mix equal parts lemon juice and water and soak your hands in the mixture for 30 seconds.
- Rinse with warm water and dry your hands.
Bonus Tip: If you don’t have lemon juice, vinegar works in a similar way. Simply soak your hands in white vinegar for a minute before rinsing.
3. Baking Soda Scrub

Baking soda is an excellent natural exfoliant that helps lift away the sulfur compounds that cause the onion smell on hands.
How to use baking soda:
- Make a paste using 1 tablespoon of baking soda and a few drops of water.
- Scrub your hands gently with the paste for one minute.
- Rinse with warm water and dry.
Pro Tip: You can also add a pinch of salt for extra exfoliation power.
4. Coffee Grounds: A Double Benefit

Used coffee grounds can absorb odors while acting as a gentle exfoliator.
How to use coffee grounds:
- Rub a handful of used coffee grounds between your hands for 30-60 seconds.
- Rinse with warm water and enjoy the coffee-scented freshness.
Why it works: The coarse texture removes lingering onion oils, and coffee has natural odor-neutralizing properties.
5. Toothpaste and Mouthwash Combo

Toothpaste and mouthwash work together to remove onion smell from hands while leaving a fresh, minty scent behind.
How to use:
- Mix a small amount of toothpaste with mouthwash.
- Scrub your hands for at least 30 seconds.
- Rinse with warm water and dry.
This method not only removes onion odor but also leaves your hands feeling clean and refreshed.
6. Salt and Dish Soap Scrub

Salt acts as a mild abrasive, helping remove stubborn onion residue from your hands.
How to use:
- Mix 1 tablespoon of salt with dish soap.
- Scrub your hands thoroughly for 30 seconds.
- Rinse with warm water.
Pro Tip: This method is particularly effective if onion smell lingers under your fingernails.
