How do I clean the mess off my deck left by pigeons?

If your deck has been installed close by to, or even under, trees then you may have encountered a high level of bird faeces present on the deck. This is due to the birds naturally roosting or nesting in the trees – pigeons being a particular culprit. Such stubborn deposits can be deep seated and hard to remove with a just a power washer and we advise not to force or increase the levels of water pressure as this may damage the deck surface.

It’s best to clean up any mess you notice before it dries, simply using mildly soapy water and a brush. However, if after that it’s still stuck, there are proprietary cleaning products you can use. It’s best to clean the whole deck area at one time so the resulting clean deck is not ‘patchy’.

Which cleaning product you use will depend on your timber type and whether you have previously applied a protective or decorative coating product to it – always check with the manufacturer.

Pigeon Mess On Deck

Solutions from Owatrol


If your deck has no previous finishing coating – whether it’s softwood or hardwood, then using Net-Trol wood cleaner is an ideal starting point. Net-Trol is biodegradable and does not contain solvents or bleach. It’s not harmful to plants and shrubs so it’s safe to use in the garden! It is also a great product for simply reviving your deck if it has weathered and looks dull.  Net-Trol can also be used as a ‘neutraliser’ after stripping products have been applied and before a final finishing product.

  • Wet the surface with clean water
  • Apply Net-Trol wood cleaner with a synthetic brush or roller
  • Scrub the surface with a Stiff brush or broom
  • Leave it to work for 10-20 minutes
  • Scrub the surface whilst rinsing with water (low pressure jet washer can be used)
  • Repeat if required

If your deck is in a susceptible location to bird defecation and you are looking for a more proactive rather than reactive approach, you could apply a protective finish to the timber to allow for easier cleaning.

Preparation and priming

Generally a system of preparation and priming is required prior to the final product application – to remove existing residues or coatings and get the surface ready to accept the new finish. The preparation you need to do to your decking very much depends on the timber species, the state it’s currently in and what has been done to it before. 

With Owatrol you have several options but do contact Owatrol directly for tailored advice on their range of products.

Prepdeck is a professional grade wood stripper which also serves as a remover for timber grade stamps and mill glaze (usually present on new timber). May be used on soft or hardwoods and thermally modified wood.

Aquanett is a powerful, biodegradable solvent-free product which will easily remove oils from your decking (please note you can only use Aquanett to remove wood oils – not paint, varnish, stains etc.). It strips out new, old and encrusted oils from exterior wooden surfaces blackened by UV rays and also cleans severely weathered wood. Please contact Owatrol for additional information and advice prior to using Aquanett on Oak and Chestnut.

Dilunett is a solvent-free paint and coatings remover which can easily and safely remove up to 8 layers of previous coatings in a single application. It is suitable for use on many previous finishes including paints, varnishes, stains, waxes and even most anti-fouling paints.

Whichever product you use, afterwards apply Net-Trol to neutralise and prevent your stripper from remaining active on the surface and eating into any future finish you apply.


Protective top coat products

Which product you choose is dependant on the timber species, the location and main use of your deck.

Linitop Prime & Finish is a multi-purpose semi-transparent penetrating wood stain including both primer and topcoat with a matt sheen finish. It is available in 13 different colours. It can be followed by a top coat of Linitop Classic for a richer colour and more hardwearing surface, good when you need to wash it down – ie to clean pigeon mess! NOT for use on Red Cedar and wood types containing an anti-oxidant e.g Iroko. Avoid wood types rich in resins.

Textrol is designed specifically for the protection of weathered softwood and hardwood  and is a saturating product which protects from within. It is available in 7 tints and has exceptional and long-lasting protection from the effects of moisture, weathering and UV rays.

Decking location advice

It is advisable to avoid installing your deck directly underneath trees as the potential for slip is increased due to falling, wet leaves – unless you also install anti-slip measures (such as deck boards with integrated aggregate strips) or you are willing to take extra time to maintain your deck and keep it free of debris.
