TO KEEP MODWOOD DECKING LOOKING GREAT, REGULAR SWEEPING AND CLEANING WITH MILD HOUSEHOLD CLEANERS ARE RECOMMENDED. FOR GENERAL DIRT AND GRIME, USE PRODUCTS LIKE SUGAR SOAP MIXED WITH WATER OR A COMPOSITE DECK CLEANER SUCH AS AQUALIS COMPOSITE BRIGHT. AVOID HIGH-PRESSURE CLEANERS, AS THEY MAY DAMAGE THE DECK'S SURFACE. FOR STUBBORN STAINS, PRODUCTS LIKE KENCO DEGREASER OR SOSAFE DECK CLEANING SOLUTIONS ARE EFFECTIVE WHEN SCRUBBED IN AND RINSED OFF GENTLY
We stock a variety of Blackhawk and Wurth stainless steel screws, as well as tools like Wurth RW20 driver bits for professional-grade installations, and brushes for oils and tint applications.
