What is a one-sentence summary of the following article?
While in the shower, rub a piece of lemon or lime over the skin that most likely has deposits of vapors from cooking such as hands, face, and arms. The acidity in lime will help to break down the essential oils that cause the lingering curry smell. Finish by washing with soap and water as usual.  Be sure to avoid open cuts or wounds on the skin as this can cause painful stinging or burning. Avoid putting on any of the same clothing articles that were used while cooking, for instance a hat or sweater. You can try using air diffusers, air deodorizing sprays, plug-ins, or scented candles. Also of great use are air fresheners that allow you to spray on fabrics. Spray all items that are in the cooking vicinity until damp, such as the carpet, upholstery, drapes or walls.  A combination of many products will work well. Be sure to carefully read instructions on the packaging label to ensure proper use. Put two cups of water in a pot on the stove and bring it to a boil. Add fragrant materials such as Kewra (Screwpine) leaves or vanilla beans/extract, and turn the heat down to a simmer. Allow it to simmer for at least one hour. The smell emitted will mask the lingering curry odor.  Screwpine leaves are also known as pandan leaves and can be purchased at the local Asian grocer or specialty grocery store.  There are no set specifications on how much screwpine or vanilla you should add. Try a few sprigs to begin with and add as needed. You can also try boiling other fragrant ingredients you have to get rid of the smell, such as 3 cups (720 mL) of white vinegar, 1 cup (240 mL) of water, and 6 cinnamon sticks. Open the windows for a day or two to allow fresh air to permeate through the residence. You may also need to replace filters in your heating or cooling systems so they don’t circulate odorous air.
Wash your face and hands with lemon or lime. Use air freshening products. Boil flowers or leaves that emit a pleasant fragrance. Allow fresh air into your home.
