This 4 pack of Sodium Per-carbonate is great to have on hand when washing wood. Always soak the surface that you are working on then apply the solution. For vertical work you can add any one of our surfactants to help the mixture cling to the surface for a longer period of time. After a good application you can let the product dwell and then wash off for a great overall look.
Each jar contains 32 oz of product.
