Are stain removers poisonous

In every instance that I know of, yes, stain removers are poisonous. This doesn't mean there isn't one out there that isn't (for instance, water, the universal solvent, is a pretty decent stain remover by itself, and it's not poisonous). But most of the ones out there are toxic. Toxic in what way depends entirely on the stain remover. If you look on the side of the box, there's a phone number you can call where they'll tell you exactly what's in the stain remover in question, and what to do if you've injested it. Also, the Poison Control phone number is: 800-222-1222 This is a no-charge 24/7/365 number to call for any poisoning questions, and they're Excellent.
