Garden fence mould will vanish if gardeners use 2-ingredient solution that 'kills spores'

Combatting Mould and Algae on Garden Fences: Simple Cleaning Solutions

Green patches blemishing your garden fence are likely signs of mould or algae growth. These common outdoor nuisances flourish in damp, shaded environments, and wooden fences, being porous, readily absorb moisture, creating ideal conditions for these unsightly growths. Removing mould and algae, especially from painted fences, can be challenging, as power washers and strong chemicals may cause damage. However, a simple two-ingredient solution offers an effective and gentler approach to restoring your fence’s appearance.

Identifying and Addressing Fence Discoloration

According to Jimmy Englezos, a senior brand manager at Ronseal, tackling mould on painted wooden fences can be achieved with household items. He advises understanding the severity of the growth and the fence material before selecting a cleaning method. For painted wood, a mild approach is often sufficient.

DIY Cleaning Method for Painted Wood Fences

For an easy and effective cleaning solution, Mr. Englezos recommends combining washing-up liquid and water:

• Prepare the Solution: Mix washing-up liquid with water to create a soapy solution.
• Apply Carefully: Using a sponge or soft-bristled brush, gently apply the solution to the affected areas of the fence. Ensure the wood is not overly saturated, as excessive moisture can exacerbate the problem if drying is hindered.
• Gentle Scrubbing: Carefully scrub the surface with the brush to dislodge the mould or algae. Avoid excessive force, which could damage the paint or finish.
• Wipe Away Residue: Use a clean, damp cloth to remove the soapy residue. It is important to avoid rinsing the area with large amounts of water.
• Prevent Spreading: Be cautious not to allow wet mould spores to contact clean surfaces, as this can lead to new mould growth.
• Drying and Repeat Application: Allow the wood to air dry completely. If mould persists after drying, repeat the cleaning process as needed.

Dealing with Persistent Mould on Timber Fences

While the washing-up liquid method is often successful, ingrained or long-standing mould may require a stronger approach. For stubborn cases, Mr. Englezos suggests an alternative two-ingredient solution using vinegar.

Vinegar-Based Solution for Stubborn Fence Mould

For a more potent cleaning action, a vinegar and water mix can effectively eliminate persistent mould spores:

• Prepare Vinegar Solution: Mix one part vinegar with one part water and decant into a spray bottle for easy application.
• Spray Affected Areas: Apply the vinegar solution directly onto the mouldy areas of the fence.
• Dwell Time: Allow the solution to sit on the fence for approximately one hour to allow the vinegar to work on the mould spores.
• Wipe Clean: After an hour, wipe away the vinegar residue and loosened mould using a damp cloth. This step should effectively remove the mould.
• Buff to Finish: Finally, buff the cleaned surfaces with a soft, dry cloth to enhance the appearance of the fence.
