Thinking about pressure washing your deck? While it’s a tempting way to quickly clean away all that built-up grime, the biggest issue with power washing is the pressure\u2014and applying too much could damage your decking.<\/span><\/p>\n

As someone who’s been in the deck business for years, I’ve heard it all, from customers who pressure washed their deck a little too enthusiastically to those who are hesitant to even touch a pressure washer for fear of ruining their investment.<\/span><\/p>\n

However, there is<\/em> a safe way to achieve a clean garden deck with a pressure washer, and I’ll guide you through it here. But if you’re feeling unsure, you may want to leave the pressure washing to the professionals\u2014or<\/em> clean your deck with my alternate tried-and-true method below.<\/span><\/p>\n

Let’s get your deck looking like new!<\/span><\/p>\n

\"\"Potential Damage from Pressure Washing<\/h2>\n

Using a pressure washer may seem like a quick and easy way to clear out all the accumulated dirt and grime; however, you need to be aware of the damage it may cause. If you have timber deck boards, a power washer’s pressure may cause splintering and damage to the timber fibres. If the timber surface already has some splintering, pressure washing will only exacerbate the issue.<\/span><\/p>\n

You may have already heard about the problems of pressure washing a timber deck. But what about composite decking? Depending on the material, a power washer can also scar boards if the pressure is too high. If the power washing becomes too intense, it can even chip the material.<\/span><\/p>\n

If you damage your composite deck with a vigorous power wash, it can affect the warranty. Damage caused by using high-pressure washing is generally not covered, so you would have to pay for your repairs.<\/span><\/p>\n

If you’ve installed quality composite decking such as\u00a0Trex<\/a>, you should wash it semi-annually (spring and autumn are the most conducive to the weather). Trex recommends a basic cleaning with a composite deck cleaner or a combination of soap, hot water, and a soft-bristle brush.<\/span><\/p>\n

Note:<\/strong><\/span><\/em> Using products containing bleach or acid will lighten the surface of Trex.<\/span><\/em><\/p>\n
