I head conflicting advise on maintaining my deck. Some say you
damage the deck by pressure washing it. Does pressure washing it
remove the pressure treated chemical out of the wood? Also, If you do
wash it is detergent required? Our deck is in good shape except in a
few shaddy spots, it has mildew. I was going to pressure wash it
then seal it. should I not pressure was the fence if I don't plan to
seal the fence? Thanks.
