Exterior Wood Cleaners

Exterior Wood Cleaners for Outdoor Timber

Exterior wood cleaners are used to clean and refresh outdoor timber that has become dirty, stained, weathered or discoloured. Our range includes products for decking, garden furniture, fencing, cladding and other suitable exterior wood surfaces.

Cleaning exterior wood is often an important part of preparing timber before applying a new oil, stain or other exterior finish. The appropriate cleaner will depend on the type and condition of the wood and the contamination that needs to be removed.

Decking Cleaner

Decking cleaner can help remove dirt and stains from timber decking before maintenance or re-oiling. Osmo Decking Cleaner is a concentrated cleaner suitable for untreated or oiled timber decking and can also be used on suitable wooden privacy screens, fencing and garden furniture.

For best results, follow the manufacturer’s instructions and allow the timber to dry thoroughly before applying a new exterior wood finish.

Garden Furniture Cleaner

Garden furniture cleaner can be used to clean suitable outdoor wooden tables, chairs, benches and other timber furniture. Regular cleaning can help remove accumulated dirt and keep outdoor furniture looking well maintained.

Liberon Garden Furniture Cleaner is specifically for outdoor wooden furniture and is part of our exterior wood cleaning range.

Wood Reviver for Greyed Outdoor Wood

Exterior timber can gradually turn grey as it is exposed to weather and sunlight. A specialist wood reviver can help clean and refresh weathered timber before it is treated with a new exterior finish.

Osmo Wood Reviver Power-Gel is designed for cleaning and refreshing greyed outdoor wood. It is recommended for applications including timber decking, cladding and garden furniture, and can be followed by re-oiling where appropriate.

Cleaning Outdoor Wood Before Re-Oiling

Cleaning is an important preparation step when an existing exterior wood finish needs to be renewed. Dirt, grime and weathering can affect the appearance and application of a new oil or stain.

A suitable exterior wood cleaner can help prepare the surface before applying products such as decking oil, garden furniture oil or exterior wood oil. Make sure the timber is clean and sufficiently dry before applying the new finish and follow the instructions for the particular product.

Cleaning Wooden Decking

Cleaning wooden decking regularly can help remove dirt and surface contamination that builds up through normal outdoor use. Osmo Decking Cleaner is suitable for untreated or previously oiled timber decking and is particularly suited to outdoor decking and related wooden surfaces.

For heavily weathered or greyed decking, a specialist wood reviver may be more appropriate than a general decking cleaner. Once cleaned and dry, the decking can be assessed to determine whether it requires further treatment.

Cleaning Weathered Exterior Wood

Weathered wood can become grey, dirty and discoloured after prolonged exposure to the elements. The correct cleaning product depends on whether you are dealing with general dirt, stains, weathering or a previous coating.

Osmo Wood Reviver Power-Gel is specifically intended for refreshing greyed outdoor timber, while general exterior wood cleaners are suitable for routine cleaning of appropriate surfaces.

Exterior Wood Cleaner for Fences and Cladding

Exterior wood cleaners can also be useful for suitable wooden fencing, cladding, pergolas, screens and other outdoor timber. Osmo Decking Cleaner, for example, is also recommended for privacy screens and fencing made from wood.

For vertical surfaces, choose a product and application method appropriate for the particular job and follow the manufacturer’s instructions.

Preparing Exterior Wood for Oil or Stain

Before applying an exterior wood oil or wood stain, the timber should normally be clean, dry and free from loose contamination. Previously treated wood may require additional preparation depending on the condition of the existing finish.

Cleaning products can be used as part of this preparation, but make sure the timber is completely dry before applying the new finish. The preparation requirements will vary between products.

Choosing the Right Exterior Wood Cleaner

The right exterior wood cleaner depends on the type of timber, its condition and what you need to remove.

For routine cleaning of decking and outdoor timber, a dedicated decking or wood cleaner may be appropriate. For greyed and weathered timber, a wood reviver may be more suitable. Garden furniture and composite surfaces may also require their own specialist cleaners.

Always check the manufacturer’s instructions for compatibility, dilution, application, rinsing and drying before using a cleaner on exterior wood.
