A StarScape ULTRA surface should be cleaned regularly in order to maintain its attractive appearance and durability. To clean the surface, it should be swept with a soft bristle broom and soapy water. To remove more stubborn dirt, it may be necessary to use cleaning products however the use of abrasive pads and wire brushes should be avoided. Before using a cleaning product, a small, discrete test patch should be chosen for a trial before general use. Cleaning products should be biodegradable and flushed with clean water to reduce the risk of staining the resin.

​

If a broom and cleaning product is insufficient to remove dirt then a cold-water power wash can be used. To power wash the surface, use only sufficient water pressure to remove dirt or contamination. Use cold water only with a fan jet, maintaining at least 300mm between the lance and the surface holding the lance at an approximately angle of 45⁰. Avoid concentration of the jet on one area by using a side-to-side sweeping motion.

​

To remove moss or algae use a stiff brush and fungicide to remove any biological growth. Flushing with clean water may not be necessary and may affect the long-term effectiveness of the treatment. It is important to follow local regulations with regard to the use of chemicals. Periodic use of a fungicide should be considered as a preventative measure in areas where conditions are likely to promote biological growth. If the use of a degreaser or acid-based cleaning product is required to remove chewing gum, tyre marks or oil stains then a small, discrete test patch should be chosen for a trial before general use.
