One of the primary reasons wood fences develop a green hue is due to moisture.
Continuous exposure to moisture from sources like rain, dew, sprinklers, and damp soil creates a favorable environment for the growth of green algae, mold, and mildew on the surface of the wood.
While it may require more effort compared to using a pressure washer, manually scrubbing away the green stains can yield satisfying results, according to Barnard Fencing.
What you’ll need to remove green stains from wooden fence
Tarpaulin
General purpose galvanised wire
Household bleach
A bucket
Protective gloves
Mild soap (that’s safe to mix with bleach)
Scrub brush
Garden hose
Wood preserve
After the stains have disappeared, wash the fence with clean water. It is recommended to use a garden hose for convenience.
Allow the fence to air dry before sanding any rough spots.
After ensuring that the stains have been removed and the fence is thoroughly dry, you can use a large paint brush to apply wood preservative, restoring the fence to its original state.
