Here is a question submitted by Lynda:
What is the easiest way to clean dried, caked-on dog poopout from between the grooves of my Nike shoes?
Here is a question near and dear to my heart since I have a dog and a backyard I have direct experience with this problem. What I do is use a pointy tool like a nut pryer(used to get the small pieces of broken nuts out of nut shells) or a small screwdriver. It gets in the groves well and will with a little patience get most of it. I also clap the shoes together (outside) as I am working and the poop works free. For a final cleanup I get up early and walk my dog across a grassy field and the morning dew does the rest. Oh the things we do for our pets! I hope that helps and good luck.
