The deck is treated wood deck about 8 years old. Every 1 to 2 years I cleaned it. This year due to mold and mildew I cleaned it with bleach, and then pressure washed it. A white residue is left after the deck dried. it looks almost like salt. How do I get rid of the residue before I put the preservative on?
