I have the Speedy B 35 in DE and she's only about 3 months old, I take care of her like crazy and a couple of weeks ago a whole 500ml glass of coke was spilt inside her and I managed to clean her up perfect, but now she has some strange black stains on the interior and I have no idea what they are or how to get them out!! On first inspection they looked like ink but looking again I definitely don't think that's what it is, it almost a looks like liquid eyeliner but I never carry make up in my bag anyway and water just won't budge it. I was wondering if I could spray a little bit of stain remover onto a damp cloth and gently wipe it or will that damage anything? Any help would be greatly appreciated!!
