It is recommended to regularly clean sand from mats with a vacuum cleaner. If they are very dirty, they are removed from the machine for washing and cleaning. Place them dry in their original place. The interior finishing can be cleaned by wiping with a damp cloth and wax. Remember to clean the ceiling as well as the upholstery. Excessive humidity during cleaning can damage the interior, causing stains, unpleasant odors or even rot. Do not use electric heating devices to dry the interior.
