Baby oil… never heard that one before
I have seen olive oil but I didn’t have it so I tried baby oil but thankfully it worked
Baby oil? You think you’ve heard it all then bam.
Cotton wool, water, small amount of polish. Repeat.
I usually do that however I had a dull spot as explained above and I was unable to get rid of it with that method so I tried the baby oil to restore the shoe and then polished it with your suggested method.
