Does UV Light Get Rid of Shoe Odor?

There are many commercial products and home remedies that claim to eliminate smelly shoe odors, some people wonder if using UV light can be an effective solution. In this article, we’ll explore whether UV light can get rid of shoe odors.

How Does UV Light Work?

UV (ultraviolet) light is found in sunlight and some artificial light sources. It has shorter wavelengths and higher energy compared to visible light. There are three types: UVA, UVB, and UVC. Of these, UVC has the shortest wavelength and highest energy. It is the most effective at killing microbes like bacteria and fungi.

The high-energy photons in UVC light damage the DNA and cellular proteins of microorganisms. This destroys their cell walls or makes them unable to reproduce. As a result, UVC light can disinfect surfaces and neutralize odors by killing the odor-causing microbes. However, UVC light at these wavelengths can be hazardous to human skin and eyes, so caution is required.

Can UV Light Remove Shoe Odors?

Because UVC light powerfully destroys microorganisms, it can be an effective way to get rid of shoe odors caused by bacteria and fungi. UVC shoe sanitizers and other UV light devices designed specifically for shoes can reduce odors.

However, simply placing your smelly shoes under general UV lights may not work as well. General UV lights don’t emit the optimal wavelength needed to neutralize shoe odors. Proper sanitizing requires UVC light exposure for at least a few minutes from a short distance. Quickly waving shoes under a UV lamp won’t have much effect.

While UV shoe sanitizers can reduce odors, they cannot replace proper hygiene. You still need to wash shoes regularly, wear breathable materials, and allow shoes to dry fully between wears. Combining these habits with periodic UV treatment can provide the best defense against stubborn shoe odors.

One drawback of UV shoe sanitizers is they only treat the insides of shoes. Any odor-causing microbes on the outside or in shoelaces, inserts, etc. may remain. And UV light cannot counteract other causes of shoe odors like cigarette smoke. Still, UV shoe sanitizers can be a handy additional tool in combating shoe odors when used properly.

Thanks to its strong disinfecting abilities, UVC light can destroy odor-causing bacteria and fungi inside shoes. Specialized UV shoe sanitizers that deliver concentrated UVC light exposure for several minutes can cut down on unpleasant shoe odors. However, UV light isn’t a magic solution on its own. You still need regular washing, drying, and other odor prevention habits for fresh smelling shoes. But as an occasional supplemental treatment, UV sanitizers can blast away shoe odors.
