Hey all! I remember reading some people clean theirs with a magic eraser, but does that work on grease? I just took my ciao out to use for the second time today and noticed a huge oil stain on the very front later in the day =( I have scotch guarded the bag, but I guess it didn't prevent it from being stained. I have no clue what it could be as I usually don't stain anything on me. I've tried wiping it with a wet towel and it didn't help. What can I use to wash it off?? Thanks!
