How can weathered garden wood look like new again?

Weathered garden wood often appears dull and grey due to prolonged exposure to sunlight, rain and pollution. Greying occurs when UV radiation breaks down the lignin in the wood, and moisture washes it away, leaving pale fibres on the surface. At the same time, dirt, algae and mould accumulate – especially in shady or damp garden areas. As a result, the wood looks aged and loses its natural charm. Instead of replacing it, a thorough cleaning can greatly improve the surface. An effective treatment removes the weathered layer and restores the warm, natural tone. This requires a product that deeply penetrates the wood structure and is easy to apply on both horizontal and vertical surfaces. Only then can outdoor wood truly look like new again.

Woca Exterior Deep Cleaner penetrates deep and cleans thoroughly – even on vertical surfaces without dripping.

Woca Exterior Deep Cleaner is the perfect solution for deeply cleaning and refreshing weathered exterior wood. Its gel-based formula has a high viscosity, making it easy to apply without dripping – ideal for vertical surfaces like fences or cladding. The product is ready to use and requires no dilution. After thoroughly wetting the wood, apply the cleaner evenly using a brush, roller or sprayer. The powerful formula penetrates deep and removes grey deposits, dirt and old oil residues. After 15–20 minutes, scrub the wood with a stiff brush and rinse thoroughly with water. After drying for at least 48 hours, the surface is ready for a new protective layer, such as WOCA Exterior Wood Oil. Thanks to this deep, yet gentle cleaning, the wood looks fresh, clean and natural – as if newly installed.
