I think the part of the shoe is called the toe vamp. Anyways I was with friends in the forest yesterday and I stepped in mud, got all over my shoe. All of the dirt is pretty much gone except for my left shoe which is why I am writing this post. I already tried the pillowcase wash method twice, I used GAIN detergent, just the regular green one. I work at a grocery store and can get any kind if it'll help remove it. I'll post a pic if I can, any help would be appreciated, Thank you!
