What works on greyed vertical wood surfaces?

Wooden fences and garden houses face constant exposure to the elements. Over time, UV rays degrade the lignin in the wood, leading to greying. This process leaves behind a dull, fibrous surface. On vertical surfaces like fences and walls, this effect is heightened as rainwater runs down, creating dirt streaks. The wood ends up appearing drab, weathered, and unevenly discoloured. Many assume that such wood is beyond repair, yet with the correct treatment, it certainly can be rejuvenated. The essential factor is using a product tailored for vertical applications: it should be non-drip and capable of deep cleaning without causing harm to the wood. A comprehensive cleaning can restore the wood’s natural hue and prime it for lasting protection against future weathering.

Woca Exterior Deep Cleaner has a thick, drip-free consistency – perfect for vertical applications like fences.

Woca Exterior Deep Cleaner is particularly effective for reviving greyed wood on vertical surfaces such as fences, façades, and garden houses. Its thick consistency ensures the product adheres well and doesn’t run, facilitating easy application even in challenging areas. It comes ready to use without the need for dilution. Once the surface is dampened, apply the gel with a brush, roller, or sprayer. The cleaner penetrates deeply into the wood to eliminate grey fibres, dirt, and old oil layers. After 15–20 minutes, scrub with a stiff brush and rinse thoroughly with water. Allow at least 48 hours for drying, after which the wood will be ready for treatment with WOCA Exterior Wood Oil to restore its natural tone and vibrant appearance.
