OXO Good Grips Fat Separator Gravy Jug 1L 5 "Doris" Doris 11 April 2019 I love this product. But to my dismay have discovered it’s not microwave friendly. The fat in the jug solidified and to remove the last bits before placing in the dishwasher I tried to liquify them in the microwave and it fried the mechanism. So people beware! A note from the team Thank you for placing your review. We confirm the jug is dishwasher safe but not suitable for the microwave, due to the material it's made from. I'm sorry to hear of your experience.
