Cleaning hardwood: how to do it safely and effectively

Hardwood is a durable type of wood that is widely used for decking, patios, and other outdoor applications. However, just like other types of wood, it takes quite a beating outdoors. Think of green deposits, dirt from leaves, or graying due to UV radiation. Regularly and properly cleaning your hardwood is therefore essential to preserve the wood's color and extend its lifespan.

In this text, you will read exactly how to clean a wooden deck, which products you should avoid, and how to treat your wooden patio afterwards.

A hardwood deck is often exposed to the open air, giving rain, dirt, moss, and algae free rein. This can make the wood slippery, discolor it, and eventually damage it. By cleaning it regularly:

• You prevent slipping caused by green deposits
• You extend the lifespan of your patio or deck
• You preserve the beautiful, natural appearance of the wood

Please note: cleaning wood is not the same as simply spraying it down with a high-pressure washer. This can damage the wood grain and make the surface rough. We therefore advise against this.

It seems like a logical choice: cleaning with green soap or cleaning vinegar. However, we strongly advise against this. Both products can do more harm than good:

• Green soap leaves behind a greasy film that actually attracts dirt.
• Cleaning with vinegar dries out the wood and can damage plants around your deck.
• The combination of water and vinegar accelerates the graying process.

Instead, use products specifically developed for cleaning wooden patios and decks.

For the best results, choose one of these cleaners:

• Osmo Patio Cleaner

For regular cleaning of dirt, algae, and green deposits on your wooden patio or decking.

• Osmo Power-Gel Wood Degreaser

For intensive cleaning of heavily soiled or greyed wood. Restores the color of the wood.

Both products are safe for your patio *and* your plants. And they do not damage the wood. This way, you clean the surface in an environmentally friendly manner.

To optimally protect wood types such as hardwood against moisture, dirt, and UV radiation, treat it with oil. This keeps your patio or decking clean and in top condition, even under severe weather conditions.

Use the following:

• Osmo Patio Oil – to keep horizontal wood parts such as decking boards clean.
• Osmo UV Protection Oil – for vertical parts such as fences or garden furniture.

These oils penetrate deep into the wood and offer long-lasting protection without the surface peeling.

Finally, you will also need a bucket of clean water.

• Clean at least twice a year, preferably in spring and autumn
• Remove leaves and dirt regularly
• Treat the wood with a special wood oil after cleaning
• Do not use a high-pressure washer or aggressive cleaning agents; hot water is not recommended
• Check annually whether a new layer of oil is needed
