I don't know if this is where I should post this but since there is no search feature available, I'm not sure if this question was already answered. So if I need to post this elsewhere, I will. How do you clean the inside of a Cabas Piano? To make a long story short, my hubby put a small bottle of milk inside and didn't close it well and it leaked!! I turned the bag inside out and you can see that something spilled inside and it looks horrible. Granted, I bought it used but still had to pay $400 for it so I'm still upset! Is there anyway that I can clean it on the inside? HELP!!!
