How do you clean hot chocolate drink from sheets?

The best things to do is to first prep the stains with a stain remover. This can either be a gel, spray, liquid, ect. Follow the direction of the product you choose. Then wash the sheet on a cycle suited (white, colors, delicates, ect.) for it with a detergent and stain remover. Repeat if necessary. If the sheet is white, you can also consider bleaching it.
