I'm not sure. The kind I use is in the nail polish remover isle at Walmart or Target and says 100% pure acetone. I use only a little bit on a cotton ball or a cotton swab and then I clean the ponies with water and soap afterwards. I even used it once to remove some gum or melted rubber band (I'm not sure which it was) that was caught in a pony's hair. It worked OK.Oh what a relief. I actually get info from collectors/site that say never touch it, so maybe it's a certain type? I've used nail polish remover and got slightly sick from the fumes, even with the window wide open.
