To clean & maintain the artificial grass, the key is to ensure that it is not covered with debris for long periods of time. Debris such as leaves will eventually begin to breakdown and can create moss or weed growth. To prevent this we recommend that you simply either use a stiff brush, leaf blower or even a hoover to clean the turf. You may also use an artificial grass cleaner or a mild detergent in warm soapy water to clean the grass, but please ensure no bleach is put on the lawn as this may affect the UV coating.
