Sunlight keeps the world alive, but can we use sunlight clean smelly shoes? Sunlight is made up of UV-A and UV-B rays. While these rays are harmful to our skin, what will they do for our shoes? Let’s see.
Does Sunlight Kill Germs in Shoes
Direct sunlight can kill some bacteria and fungi, but not necessarily viruses.
In your shoes, sunlight will dry the insides, eliminating the damp environment in which bacteria and fungi like to thrive. They will also kill some of the bacteria and fungi in the shoes.
Your shoes will need to be in direct sunlight. The surfaces will need to be fully exposed for hours at the hottest time of the day. The hotter the sun is, the better. And the longer you can leave your shoes in the sun the better. UV rays are usually strongest between 10 am and 4 pm.
One study showed that fungal infections were significantly reduced for 3 days of direct sun exposure in socks of patients that has tinea pedis infections (foot fungus) while another one showed that sunlight killed more than double the bacteria in one room compared to another room that had no sun exposure.
However, the UV-A and UV-B rays that we get from direct and visible sunlight are not strong enough to efficiently kill viruses. For this, you would need UV-C rays, which do not reach the earth directly.

Does sunlight help remove odor from shoes?
Sunlight can help to lessen or get rid of odor from shoes.
Shoe odor is most commonly caused by bacteria and fungi that react to the sweat and dampness in our shoes. When these elements are removed, the odor goes away or at least lessens.
Direct sunlight will dry your shoes, as well as get rid of some of the bacteria and fungi that cause the odor.
However, this is not a permanent fix. If your shoes can tolerate this treatment, you may need to sun out your shoes often. I recommend using a disinfecting spray like Lysol every day and then sunning out your shoes once per week. Wash your shoes once every month or every few months (depending on how much you wear them and how dirty they are).

How To Use The Sunlight To Clean Smelly Shoes
This method aims to use the rays of the sun to dry and disinfect your shoes.
- If your shoes are very dirty and smelly, I recommend washing them first. If they are not as bad, you can skip the washing. For white shoes, you can also coat them with your whitening agent (any bleaching product) first.
- When you are ready to place your shoes in the sun, check your local weather forecast to make sure it will be sunny all day.
- Then open them up as much as possible. Remove any laces and soles from the inside.
- Place the laces and the soles (washed or unwashed) in the sun, separately to dry.
- Place your shoes in the sun in a position that will drain any water out of them if they are wet. Or, if they are not wet, place them in a position where the sun will get as far inside the shoes as possible.
- Make sure that there is nothing to block the sun from hitting the shoes directly.
- Leave your shoes in the sun all day if possible or for a few hours at least. If they are wet, make sure that you leave them until dry.
- If needed, you can repeat the sunning process consecutively for a few days after that.
