I haven't heard of the product Soft Scrub being used on dolls--I think whoever used the term probably meant a gentle scrub with baking soda, though I could be wrong.
Baking soda is what is recommended to clean the vinyl(even the "doll cleansing powder" that AG sells is nothing but baking soda!), and if it were me, that's what I'd use.
The ebay seller is probably not being quite straight with you(though I hate to say something negative about someone I don't know)--they can honestly say THEIR home is smoke-free, but not mention that the doll is from a smoking home, and they're just re-selling her. With my smoke-reeking doll, I forgot to ask about smoke, so I figured I deserved what I got, and left positive feedback--aside from the smoke, the seller deserved it. However, when reading that seller's feedback, a previous customer mentioned that their item was "pretty smokey, but as described". Uh-oh, I thought. My doll had already shipped by then, though, so I wasn't surprised by the smell. Interestingly enough, the doll had been packed with a fabric-softener sheet on her chest inside the bubble wrap, apparently in a vain attempt to deodorize her en route! Didn't work at all, but at least the seller was apparently aware this doll had smoke issues she hadn't mentioned. So, lesson learned--ALWAYS ask about odors! Specifically on the doll, not just whether the home is smoke-free, or who smokes and who doesn't, etc. Sorry to babble on so, but I hope others will benefit from my experience.
Good luck with Kailey! [img]smile.gif[/img]
