Make every cleanup easy with the Blackstone XL Rear Grease Cup Liners. Our patented 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, once you're done, push the excess oil and scraps of food to the Rear Grease at the back of the griddle, and the liner will easily catch the mess. Once the liner is full, close the lid, discard, and replace it with a fresh liner to make cleanup a breeze. Use the XL Grease Cup Liners with your XL Rear Grease cup Blackstone griddle.
