Cleaning wood: here's how to do it indoors and outdoors

Wood is a beautiful, natural material that brings atmosphere and warmth to your home and garden. But just like other materials, wood requires maintenance. Whether it concerns a wooden table, decking, facade, or piece of furniture: dirt, moisture, and grease penetrate the surface and can damage the wood. By cleaning the wood regularly, the color stays brighter, the material lasts longer, and you retain the natural look you chose.

In this tutorial, you will learn everything about cleaning wood – from soft indoor furniture to outdoor hardwood – and which products are best to use for different types of wood.

Outdoor wood is continuously exposed to rain, UV radiation, dirt, and green deposits. Regular cleaning helps keep the wood surface looking beautiful and prevents slipperiness.

What to use – and what not to use?

Many people use green soap, vinegar, or a pressure washer to clean a wooden patio or deck. However, this is often not a good idea:

• Green soap leaves behind a greasy film that attracts dirt.
• Cleaning with vinegar can dry out the wood and affect the color.
• A pressure washer makes the surface rough and damages the wood grain.

It is better to use products specifically developed for cleaning wooden patios and decks:

• Osmo Patio Cleaner: for periodic maintenance and removing dirt and green deposits.
• Osmo Power-Gel Wood Degreaser: for intensive cleaning and restoring the original color of grayed wood.

Both products are safe for plants, effective against dirt, and gentle on wood.

After cleaning, it is important to protect the wood against aging and moisture. This prevents cracks, graying, and mold.

Use the following for this:

• Osmo Terrace Oil for horizontal surfaces (for example, in Bankirai color)
• Osmo UV Protection Oil for vertical surfaces such as fences or facades

Both oils penetrate deep into the wood, are breathable, and provide long-lasting protection against UV radiation and rain. A few drops of olive oil are insufficient.

Grease stains, dust, moisture, and dirt can also damage wood indoors. Think of oak furniture, oiled tables, or a wooden floor. Each surface requires a tailored approach.

Daily maintenance

Whether you have an oiled wooden table, oak furniture, or a wooden floor – regular cleaning is important to keep the wood beautiful and in good condition. Always use products that are mild and specifically developed for wooden surfaces.

Has the wood become dull, are scratches visible, or are wear spots appearing? Then an intensive approach is required involving a combination of cleaning and restoration.

Step-by-step plan: thorough cleaning and restoring the protective layer
1. Clean with Osmo Intensive Cleaner
Apply the Intensive Cleaner to the soiled surface and clean with a cloth or pad.

2. Use the Osmo Green Pad
Scrub lightly with the Green Pad to remove stubborn dirt or old residue.

3. Remove the dirt
Wipe off loosened dirt with a damp cloth.

4. Apply Osmo Maintenance Oil
Allow the surface to dry, then apply the Osmo Maintenance Oil to nourish and protect the wood again.

When cleaning untreated wood (such as rough tables or old pieces of furniture), people often reach for green soap, baking soda, or cleaning vinegar. This is not a good idea.

Why not:

• Green soap leaves a greasy residue.
• Cleaning vinegar and baking soda can dry out or discolor the wood.

Instead, use a mild cleaner such as Osmo Spray Cleaner, always work with a soft sponge or cloth, and dry thoroughly with a dry cloth.
