Cleaning your timber decking probably seems like a chore that is thankless and boring, but a regular routine can help to prolong its life and reduce the need for expensive repairs down the line. Here we look at what you need to clean decking thoroughly, and show you how to do it.
Equipment for cleaning a timber deck
- Stiff brush
- Bucket
- Cleaning solution (proprietary or homemade – see later)
- Hose or pressure washer (optional – see later)
Clear the decked area before cleaning
This is an important step as it is impossible to clean your decking thoroughly if there are planters and furniture on it. Remove everything that normally sits on the decking – furniture, plants, accessories – before sweeping the surface with a stiff bristled brush. Brush aways all loose debris such as leaves, dust and dirt and pay particular attention to any moss or mildew that may have formed on the timber. For hard to reach places, a dustpan and brush are useful.
Cleaning timber decking
To pressure wash or not to pressure wash? This can be a cause of contention to many people. Pressure washing will definitely save time but can cause damage to timber decks. However, if done correctly and carefully, a pressure washer will make short work of removing dirt and stains but do make sure you use a maximum pressure of 500psi. Keep a good distance from the surface of the decking and use sweeping movements. Alternatively a hose on a gentle setting can be used which may be kinder to timbers.
Remove stubborn dirt and stains from timber decking
Using a pressure washer or hose should tackle most dirt but deeper stains may need more work. A proprietary deck-cleaning solution can be used (follow the instructions carefully), or a homemade solution of 5 tablespoons of ammonia-free laundry detergent, mixed with 1 litre of bleach and 12 litres of water is perfect. Simply apply the cleaning solution to the decking, scrubbing with a brush to remove ground in dirt, grease, moss and mould. The solution can be rinsed away using plain water.
Treating timber decking
Once you have cleaned the decking, you should take steps to prevent the growth of mould and mildew. Protek Wood Preserver can be used to protect against mould and fungi, and also insect infestation. Use by itself, on dry decking, or follow with Protek Restol Wood Oil or Protek Decking Stain, for additional protection.
How often to clean timber decking
Loose dirt and debris should be cleared regularly, and not allowed to build up. This is particularly important in autumn when falling leaves can collect and cause problems, and it will help to stop decking being slippery. Deep cleaning with a cleaning solution can be carried out whenever you feel it is necessary but at least once a year.
