I had a date last weekend, we went out for ice cream and for a walk. After good conversation she pointed out I had a stain on my Polo, so while cleaning if off, I noticed I had a couple stains on my leather moccasins! I wiped but wasn't too concerned because I was having such a good time. Next morning I go to clean the shoes with water and nothing! Can some one give me some tips? They are mid-brown colored.
