Dirty awnings can be washed using clean water and a soft brush. Do not scrub and never use detergents.
If this does not clean the awning, we recommend applying awning cleaner, this is available from your supplying retailer or authorized repair centre. It is always best to first test a cleaning product on a part of the awning you cannot see in case of any adverse effects the cleaner may cause.
Tree sap should be removed as soon as possible to prevent permanent damage to the material.
