MOST of the materials we use in art class are washable materials that will NOT stain your students clothes. But if we do have to use acrylic paint, and it gets on clothes, it will stain. Don't throw them in the wash!!! Use Murphy's Oil Soap to take the paint out of your child's clothes. Murphy's Oil Soap is a wood cleaner and can be found in the cleaning section of Wegmans or Tops.
