The suggestions for removing stains have been compiled as a service to our consumers. We are unable to guarantee or be responsible for the results obtained by these procedures. You may also wish to consult your local cleaner for further recommendations.
Before attempting the stain removal method, test each procedure on an inconspicuous area of the material or surface to be cleaned. Please be advised these stain removal methods involve hazardous products and are intended only for adult use. Crayola does not recommend children attempt these procedures.
In many procedures, specific brands of products are recommended. These are brands that performed most effectively in our laboratory. Always check individual containers for recommended procedures and warnings. Competitive brand products may work equally well.
