How To Use


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 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.

Special note: Only add SMC Peroxide Cleaner to application equipment that is clean and free of dirt and debris. Additionally, never return unused material to the original container that the SMC Peroxide Cleaner came from.


Store in a dry place at temperatures between 40°F (4.5°C) and 90°F (32°C). Store securely closed and upright in the original container. Do not store in direct sunlight as this will reduce the potency of the product.

Avoid shipping or storing below freezing or above 100°F. If product freezes, thaw at room temperature and shake gently to remix components. Store in a locked area inaccessible to children.



  1. Do not take internally.

  2. Apply when surface temperature is between 40 – 95 °F (5 – 35 °C).

  3. Protect surrounding areas and clothing from product contact. Avoid contact with metals.

  4. Keep away from plants, water and soil.

  5. Once mixed, solution should NOT be left in a sealed container. It will continue to give off oxygen and the container may rupture and cause damage.

  8. Wash hands thoroughly after applying.
