I inherited a fabulous pair of Florsheim Kenmoors in brown Scotchgrain from an uncle. He wore them literally once and kept them in his basement for the last 20 years. A powerful musty smell coming out of them was so strong that I have left them outside for the time being. I wanted to kill the mold but I am at my wits end. Here is what I have done to them thus far: I Soaked them in 50-50 white Vinegar - water, completely submerged for 8 hours, then let them dry in the sun for 3 days.....still the hellish smell persists. There were no mold spores on the shoes and no powdery residue. These shoes seemed immaculate, but I just can't rid them of this smell....What to do? I am prepared to give them a second vinegar bath, this time for 3 days but is there a proven and faster way? Please discuss.
