Clear the water-based stained deck of all furniture and other items.
Sweep the deck first using a large push broom. Protect the areas around your deck using large sheets of plastic. For example, any plants around the deck should be covered.
Apply deck cleaner that's safe to use on water-based stained to the lap marks and other stains using a paint roller.
Spread the deck cleaner using the stiff push broom. The cleaner should never be in puddles on the deck surface.
Watch the cleaner carefully as you apply. No area should ever get dry.
Scrub the lap marks using a stiff bristled cleaning brush. Continue scrubbing until the marks disappear.
Rinse the cleaner from your deck within 10 minutes of applying it using your garden hose and a spray nozzle. If you think a lot of scrubbing will be needed to remove the marks, clean small areas at a time.
