How To Use


Allow a 24-hour cure time to determine the ease of application and desired results. STAIN-PROOF™ SMC Peroxide Cleaner can be applied with a pump sprayer, watering can or mop/brush. When applying, saturate the affected material, then agitate the substrate with a nylon bristle brush to generate a profuse foam. Reapply a light coat of STAIN-PROOF™ SMC Peroxide Cleaner and let stand for 5 to 10 minutes. Agitate the substrate a final time and let stand for another 5 to 10 minutes. Use a clean water rinse to get the suspended dirt and debris away from the substrate. On deeply soiled materials an additional one or two applications may be necessary to restore the substrate to its original look. The full brightening effects will be seen within 24 hours as the surface dries.
