What vegetable can be used to soften shoe leather as well as deodorize the shoe?
I am not sure about softening shoe leather but shoving a pea up each nostril will get rid of the smell. Although not vegetable based, I have found the following tip on a web site: How to Soften Leather Shoes: Sponge with black coffee. I suppose if the coffee has sugar in it, the shoes would smell sweeter.
