Make every cleanup easy with the Rear Grease Cup Liners. The Blackstone Rear Grease Management System makes it easy to manage the grease, but our liners make disposal convenient and mess-free. Place the liner in the grease cup before you start cooking and push the excess oil and scraps of food to the Rear Grease at the back of the griddle. The liner will easily catch the mess, and once it’s full, simply discard it, and replace with a fresh one for easy cleanup next time.
