I'm hoping someone here has advice. I have an issue with a pair of shearling lined shoes that bleed black dye on my feet. The shoe is Birkenstock Blair oiled leather shearling lined clog. I've considered dampening the shearling with vinegar and placing the shoes to dry in front of a heater in attempt to set the dye. Before errantly proceeding, I wanted to request advice from anyone who has experience dealing with a similar issue. Obviously, I cannot submerged the shoes to wash the shearling. Thanks in advance.
