Why clean your deck? We invest a lot of money and effort in building beautiful outdoor decking areas but they tend to get neglected. Your deck is like any room in your house but it is exposed to the elements. Sun, rain and dirt blowing onto the boards can create unsightly ugly decks. Your deck is made of weather resistant material but over time it will deteriorate unless it is properly cared for.
Sweeping your deck is the most basic step you can take. Keeping it free from leaves and twigs will make a big difference long term, not only to its appearance but also to its potential performance. Leaves and twigs can contain tannins which can stain your decking. Piles of leaves can retain moisture and lead to mould or even rot in extreme cases. Use a stiff broom to regularly sweep your deck and try to remove any leaves that are stuck between your deck boards. The more regularly you sweep the easier it will be to maintain your deck.
Along with regularly sweeping your deck, at least once a year it’s important to give it a thorough clean. In the same way that you regularly mop the floors around your house, you should do the same for your deck. Using just soap and water, give your deck a good scrub and it will make a big difference to the appearance.
Sweep your deck with a stiff broom, give it a wash with soapy water and then treat it with a long acting surfactant. There are a variety of products available and most commercially manufactured products will work to varying degrees. Keep in mind that the effectiveness of any of these products will depend on the environment it is used in. Lots of rain and sun will probably mean your protection will wear out faster. The main thing to remember is if you see something unsightly on your deck, clean it! The longer you leave it the harder it will be to remove later.
