We all know that spending too much time outside on a sunny day can be bad for our health. But the ultraviolet radiation from the sun can be a natural and effective way to deodorize and kill smelly bacteria in hard-to-wash household items. On a sunny day, bring items like area rugs, yoga mats and throw pillows outside. Place them on a clean tarp away from animals and cars. Allow the items to absorb the sun’s rays for several hours to fully deodorize them.
