I did not know where to get this question answered so I decided to submit it to the boys at The Mercedes Digest. Somebody there surely knows the answer. After all, it is an automotive question, right?
After wearing my COVID face mask in the car, I leave it on the dashboard so the sun's rays have an opportunity to kill any harmful microbes that may be present. Which brings up the question of whether or not the ultraviolet rays can penetrate glass, specifically automotive windshield glass. It is my understanding that to kill microbes, a wavelength of 254 nanometers is necessary, most of which doesn't make it to earth. So is this a useful practice or a fool's errand?
