Even though WPC decking is low-maintenance, it should be cleaned once or twice a year.
Stains, scratches, and discolorations are more visible on the composite material WPC than on stone or wood. Especially in covered areas of the wpc decking, stains persist longer. However, you can quickly remove these stains and discolorations. Usually, a soft broom, dish soap, and plenty of water are sufficient for cleaning WPC decking. Do not use brushes with metal bristles as they can damage the surface of the decking. The first cleaning should be done right after installation. Scrub the decking in the longitudinal direction with a grease-dissolving dish soap or soapy water. Rinse thoroughly with clear water afterwards.
Cleaning with a pressure washer is very effective but roughens the surface of the decking. This can make dirt and green algae adhere better to the decking. On the other hand, such roughening can also occur over time without a pressure washer. Therefore, especially with older WPC decking, you can use a pressure washer if you follow some basic rules.
Maintain a minimum distance of 30 cm
Since fats and oils do not evaporate on the rough WPC surface, stains can form. Ideally, you should wipe away these substances immediately. Scrub these areas with conventional all-purpose cleaner and warm water, and rinse thoroughly with plenty of water. Remaining stains will disappear over time due to weathering.
Home Remedies for Removing Algae Stains on the Boards
During winter, moss, algae, and dirt tend to accumulate on the terrace. Use a spray bottle or watering can to distribute vinegar cleaner on the affected areas. Scrub these areas with a scrubbing brush or an appropriate brush. Rinse with clear water afterward.
WPC boards require relatively little maintenance. However, there are cleaners and surface protection products specifically designed for this material. Regularly using these products correctly promotes the longevity of the terrace flooring.
