...when you can't get a stain out of your bag? I carried my green optic signature ladybug hobo for about a week and it got a few stains on it. One of which was a red, juice looking stain, that came out with the signature cleaner...but when I tried to get out what looked like a soiled spot it would not come out for anything. Is there anything else you've tried other than the signature cleaner that might get it out? I'm really not sure what the stain is.
