Okay, these are not Chucks, they're Ed Hardy (you caught me). But I still run into the same problem all Chuck owners run into, how to get the tops clean? At least for me, water and soap just doesn't do the trick. I've even tried cleaning them in the washing machine but I find that thrashes the shoes. So from trial and error, I've discovered that "Mr. Clean Magic Erasers" will get the tops sparkling white.
*I'm told there's a Japanese version of the Mr. Clean Magic Erasers sold at Daiso. Apparently it comes in a giant block and you can cut it up into smaller sponges. This would probably be a cheaper alternative to the Mr. Clean Erasers.
