What’s a good spring treatment for wood?

After winter, outdoor wood often shows signs of dirt and weathering. Rain, frost, and lack of sunlight allow dirt, moss, and algae to accumulate, while UV radiation causes the wood to turn grey over time. This combination not only makes the wood less attractive, but also more vulnerable to wear. A thorough spring treatment is therefore essential to restore decks, garden furniture or fences. An effective cleaner doesn’t just remove surface dirt – it penetrates deep into the wood fibres. At the same time, the surface must be properly prepared for further treatments with oil or stain. Doing this in time extends the life of the wood and restores a fresh, natural look as the outdoor season begins.

Woca Exterior Deep Cleaner removes winter residues and prepares wood for treatment and oiling.

Woca Exterior Deep Cleaner is the ideal solution for cleaning outdoor wood after the winter months. This powerful, ready-to-use gel removes greying wood fibres as well as dirt, moss, and algae that build up during the cold season. Thanks to its high viscosity, the product does not drip and is suitable for vertical surfaces such as fences. Once the wood is thoroughly wet, the cleaner is applied evenly with a brush, roller or sprayer. After letting it work for 15–20 minutes, the surface is scrubbed and rinsed with plenty of water. The result is a clean, smooth wood surface that can be treated after at least 48 hours of drying – for example with WOCA Exterior Wood Oil. This ensures a fresh and well-protected surface for the start of the outdoor season.
