How to Remove Green Stuff from a Wooden Fence

Removing the Moss

• 1). Fill a bucket with 3 qt. warm water. Add 2/3 cup of TSP (trisodium phosphate), 1/3 cup laundry detergent and 1 qt. liquid chlorine bleach. Put on a pair of thick rubber gloves before applying the cleaner to the wooden fence.
  
  
• 2). Apply the moss cleaning solution to the fence using a scrub brush. Scrub the entire area affected by the green stuff, not just the moss itself. Scrubbing the entire affected area will ensure that you do not miss minute sections of moss growth.
  
  
• 3). Rinse the fence thoroughly with a garden hose to remove all traces of the cleaning solution. The green stuff will come off completely during the rinsing. Allow the fence to air-dry for 1 to 2 days and then repaint.
  
  

Repainting

• 1). Repaint the cleaned area of fence with whatever was on it previously. Most fencing has a coat of exterior paint, exterior stain or exterior clear polyurethane sealer.
  
  
• 2). Pour the paint, stain or polyurethane sealer into a paint tray. Apply the paint, stain or polyurethane sealer to the fence with a roller, but use a paintbrush to get in-between the wood slats.
  
  
• 3). Allow the first coat of paint, stain or polyurethane sealer to air-dry before applying a second coat. Because most exterior paints, stains and sealers are oil based, they usually require a 24-hour waiting period to fully dry between coats. Allow the fence surface to dry overnight and tackle the second coat the following day.
