How to get the chemical smell out of baby toys?

I just bought my baby a new rattle by Fisher Price. It was inside packaging when I bought it so I didn’t realize until I got it home that it smelled horrible like chemicals. The instructions on it said to wash before use in warm soapy water. Which I did and do with all of her new toys, but it didn’t take the awful smell away, I don’t want her to put it in her mouth that way. How do I get the smell out? I tried soapy water and baking soda. What else should I try?
