WASHINGTON — QUESTION:
If you get hit with pepper spray, will a mixture of water and baking soda sprayed on your face stop the burning sensation?

As clashes between police and protesters continue, some people are sharing this tip online. To get an answer, our Verify researchers contacted experts in chemistry, dermatology and poison control, and looked at information from the Centers for Disease Control and Prevention.
Chris Cramer said there’s no evidence the baking soda solution would work, because the active ingredient in pepper spray isn’t an acid - it’s capsaicin, the heat-producing compound in chile peppers.
Cramer says capsaicin is oil-based, so it won’t dissolve in water.
“When somebody is sprayed with pepper spray, their eyes were irritated and they might be rubbing their eye," Dr. Kelly Johnson-Arbor said. "If something small, particulate, like baking soda, gets in the eye, that can make the irritation worse and actually lead to more serious injury, like even a corneal abrasion or a corneal ulcer."
Dr. Adam Friedman said using baking soda this way could even cause an alkaline burn.
So we can Verify, experts say using baking soda and water is not an effective way to neutralize pepper spray.
Our experts, and the Centers for Disease Control and Prevention, suggest using soapy water on your skin and irrigating your eyes with water instead.
If you choose to use soapy water, be careful what type of soap is used. Baby shampoo is a good choice, as it will generally not irritate eyes -- it is formulated with this in mind.
However, if one chooses something like Dawn Dishwashing Detergent or any soap containing anionic surfactants, eye contact should be avoided as it may cause stinging, tearing, itching, swelling, and/or redness. If contact occurs, eyes should be rinsed with plain water.
