How difficult are cork tiles to maintain and keep clean?
For the proper maintenance and to protect against moisture leeching into the seams, apply an additional coat of water-based varnish to the tiles after they are installed. Before applying the finish, the tiles must be clean and free of adhesive. Once you have applied the second coat of finish, to keep the cork tiles clean all you must do is vacuum regularly, or sweep with a fine bristle broom followed by damp moping with a ph balanced cleaner. Do not use any products that contain ammonia or abrasives. You should never wax your cork floors.
