The tray is notdishwasher safe, but that's not a a problem as you simply won't need to use it! Residue just washes off! Dry with a soft tea towel.
The non-stickiness is a dual layer and internally reinforced 'Whitford Eclipse' coating. Some marks on the underside of the edges where the tray contacts the oven runners are normal and won't affect the life of the tray.
