Hello, and thank for reviewing the Ironwood 885 Drip Tray Liner. There haven’t been any recent changes to the drip tray liners, so if you find that they continue to perform inadequately, and nothing is being done differently when using them, then please reach out to Traeger Customer Service and one of our agents can check the liners with you to see what needs to be done. In the meantime, use caution with any liners that inhibit proper grease flow, and if the grease continues to pool excessively on the tray, make sure to replace the liner prior continuing to use the grill.
