I have been using Corte-Clean on the deck and dock, made with Tamko EverGrain Composite Decking, at my vacation home on Norris Lake in Tennessee for several years. Annually I have a problem with the growth a green “moss” on the deck and dock in areas of shade and moisture. One or two applications of Corte-Clean annually keeps the composite looking new. I just ordered 4 more bags today. I LOVE it. Jim
GREAT Product Tamko EverGrain!!!
