How to get chilli burn off your hands
Wash with soap or dish detergent and warm water, because capsaicin barely dissolves in plain water. For lasting relief, soak your hands in vegetable oil: in a controlled test, cool water helped more at first but oil gave better long-term relief. Next time wear gloves, and keep your hands away from your eyes.

Why water alone does not work
Capsaicin, the irritant in hot peppers, is an oily compound that is practically insoluble in cold water [5]. A dermatology review explains that washing skin with water or vinegar alone is not enough to dissolve it [1].
Handling peppers can cause redness, burning and itching of the skin, a reaction called irritant contact dermatitis [1]. Peeling peppers barehanded can cause prolonged burning pain and redness, but not blisters [2].
Steps to ease the burn
Washing with soap, detergent, baking soda, or oily compounds that act as solvents for capsaicin can relieve the burn [1]. Poison centres also list soaking in a liquid antacid, and soaks in vegetable oil or diluted vinegar, as giving relief [3][4].
- Wash your hands thoroughly with soap and warm water [4][7], or with dish detergent [1].
- Soak your hands in vegetable oil for longer-lasting relief [2][3].
- If it still burns, try ice water, a liquid antacid soak or a diluted vinegar soak [1][3][4].
- Wash again with soap and water before touching your face, eyes or contact lenses [6][8].
What the research tested
A 1987 study from the New Mexico Poison and Drug Information Center had 20 women immerse their hands in green chilli slurry for 40 minutes [2]. Afterwards one hand went into cool tap water and the other into vegetable oil, for 75 minutes in total [2].
Cool tap water gave more relief at first, while vegetable oil gave better long-term relief [2]. Cold water is often recommended, but poison specialists note it seldom provides long-lasting relief [4].
How to prevent it
Wear rubber, latex or nitrile gloves when working with hot peppers [3]. After handling them, wash your hands with soap and water before you touch your face [6].
Do not touch your face or eyes after preparing hot peppers, and open a window or use fresh air while cooking them [3]. Contact lens wearers should wash with soap and water and dry their hands before touching their lenses [8].
When it keeps burning
What doesn’t work
- Rinsing with plain water only: capsaicin is practically insoluble in cold water, so water alone does not remove it [1][5].
- Relying on cold water for lasting relief: it helps at first but seldom lasts [2][4].
- Vinegar alone as a cleaner: it does not dissolve capsaicin, though diluted vinegar soaks are reported to ease pain [1][3].
- Touching your eyes, face or contact lenses before washing [3][8].
Questions
Does oil really help chilli burn on hands?
Yes, in one controlled test. Vegetable oil gave better long-term relief than cool tap water, though water helped more at first.
Why does soap work better than water?
Capsaicin is practically insoluble in cold water, and soaps, detergents and oily compounds act as solvents for it.
Does milk work on hands?
Milk is studied for mouth burn, not skin. For hands, the sources list soap, detergent, baking soda, oil soaks, antacid soaks and diluted vinegar soaks.
How do I stop it happening again?
Wear rubber, latex or nitrile gloves when working with hot peppers, and wash your hands with soap and water before touching your face.
What is Hunan hand?
It is the name given to persistent burning and pain in the hands after repeated exposure to hot peppers.
