How to clean your decking, including composite black spot removal

Ultra Decking want to supply help and advice for all decking users and in this article we want help customers that have been affected by sales of a first generation composite decking product. If you get black spots on your decking this would be due to you purchasing the first generation of composite decking, which experienced a few teething problems. Third generation is now a widely recommended purchase. Take a look at our ultra decking premium or platinum to ensure these problems never happen again.

All Decking companies mention maintenance free decking, but there’s no such thing as maintenance-free when it comes to any outdoor product. The reasons are many. For starters, the sun’s ultraviolet (UV) rays are so powerful they break apart metal atomic bonds. Simple paint, plastic or wood molecules and fibres are child’s play for the sun. Mother Nature is also quite adept at showering everything outdoors with mould spores, algae, dirt, diesel soot, dust, etc. Add water to this slew of ingredients and you’ve got perfect conditions for mildew, mould and algae growth on any surface. At the very least, maintenance involves periodic cleaning. You can clean some things with regular liquid dish soap and water. Tougher stains from barbecue grills, tree sap, mould, mildew and algae may need more powerful powdered oxygen bleach mixed with water. We think you can get some peace of mind, but it’s going to take a little work on your part. Fortunately, it’s easy to do.

Clean the decking first and then apply a mist of copper sulphate solution to the decking. Copper sulphate is readily available, and farmers have used it for decades. It controls fungus diseases, makes up for copper deficiencies in animals and other things. If you drink wine, then you have to appreciate copper sulphate! Vintners use it.

For a quality composite decking board at a great price, Ultra Decking’s Premier range is simply unbeatable.
