To remove chocolate stains from a kid's bed, you need to remove the excess chocolate, if there is any, first. You can either use the vacuum hose or remove it with light dabs of towel, or paper towel. Once the stain is all that remains, put some detergent or stain remover on the stain. Then, blot the spot again with the towel or paper towel. Repeat the process as much as needed.
