The common 35p kitchen staple that melts away ugly algae on fences

A common staple could save your fences from algae and costs just pennies. Gardening experts have put together their advice for getting rid of the ugly substance on wooden items in the garden.

Algae thrives in damp conditions, making the UK climate the ideal environment and can leave sheds, fences and wooden furniture looking uninviting and unsightly. Now experts at have given some great advice for tackling the issue.

A spokesperson for the company said: “Removing from sheds, fences, and garden furniture is essential for prolonging the lifespan of these structures and keeping them looking good. If it’s left untreated, algae growth can lead to wood decay, surface discolouration, and slippery surfaces, posing safety hazards.

“Regular maintenance, including cleaning and applying protective sealants, can prevent algae growth and keep your garden structures looking their best year-round. Sorting out the problem will keep your garden looking good and prolong the lifespan of your wooden shed, fences and garden furniture.”

GardenBuildingsDirect recommends several ways to remove algae, one of which costs mere pennies: white vinegar. A small bottle from Sainsbury’s or Tesco costs 35p.

To remove algae from wooden garden structures, mix one part white vinegar with two parts water. Begin by brushing off any algae with a soft-bristled brush or broom. Apply the vinegar-water solution and let it sit for 15 minutes before rinsing it off. For tougher stains, reapply the solution.

Alternatively, you can use the pressure wash, but ensure that no water enters the interior. If it’s likely to get inside a shed, for example, remove the contents and leave the door open to allow for quick drying. Start with a low-pressure setting to avoid damaging the wood.

Various algae removers are available but be sure to read the labels and follow the instructions. If possible, opt for an environmentally friendly option.

After removing the algae, treat your fence or shed with a good wood preservative. This will kill any remaining algae spores and help prevent regrowth for a few years.

Keeping the wood dry can be challenging, but you can minimize moisture by trimming back overhanging branches or plants, allowing more sunlight and improving air circulation around the wood.

Preventing algae altogether is also possible. Try to identify the underlying cause. If it’s poor drainage or too much shade, then these can be fixed. Also make sure to apply a wood preservative to protect wooden surfaces.
