Overview

• Experts advise mixing one part bleach with two parts warm water to tackle green algae on wooden fences.
• Homeowners should scrub panels with a firm brush then leave the solution to sit for 30 to 60 minutes before rinsing.
• After cleaning, fences require 24 to 48 hours of drying before any paint, stain or sealant can be applied.
• A final coat of waterproof stain and sealant seals out moisture and stops algae from returning.
• Total expenses for a spot treatment remain under £5 with Tesco bleach and shared Tool Station sealant, and nearby plants must be covered to avoid bleach damage.
