Crayola Sidewalk Chalk is a molded chalk made of Plaster of Paris and color pigments. Although it is designed to be used on sidewalks and driveways, the chalk contains colorants, which may stain clothing and other household surfaces. If the chalk is used on a newly poured sidewalk or driveway, there is a possibility that the open surface pores in the concrete could absorb the colors.

We suggest testing Crayola Sidewalk Chalk in an inconspicuous area and then washing it away with water. In most cases, chalk markings wash away with the first rainfall if used on a paved or poured surface that is more than two years old.

Crayola offers stain removal suggestions as a service to consumers. You can find this information on the Crayola Stain Removal Tips page.

Please bear in mind that while all stain removal suggestions have been tested in our laboratory, results are not guaranteed. We recommend testing any suggestion in an inconspicuous area first.
