Using your Broil King 68590 grill cover is easy. Just place it over your built - in Imperial 600 series grill and use the retention system to secure it. The molded rubber handles make it convenient to remove when you want to use the grill. When it comes to maintenance, clean the cover regularly with a mild soap and water. Avoid using harsh chemicals as they may damage the PVC and polyester fabric. Store the cover in a dry place when not in use to prevent mold and mildew. Also, make sure the grill is cool before covering it to avoid any heat - related damage to the cover.
