Hey all - I was wondering if there is anything I can do to remove a blue stain that seems to have appeared on a part of my new hayden harnett havana hobo in chalk. It's quite evident on the white leather! It seems either some color from shirt or my jeans seems to have rubbed off...has anyone else had a similar experience or know how to fix it?? I've only used my bag a few times and am so dismayed that it already has a giant blue stain on it. Any advice would be great. Thanks!
