Use a metal one with some baking paper. I'm not trying to be a smart arse, I just never knew of the existence of non-stick baking trays until this very moment.

I do know non-stick trays and pans are stilly metal, it's very late so I slipped up is all.

I use foil on mine, but yes, do what >>15053 says.

Same thing has happened to mine - it rusts each time I wash it now. No more drip dry :(
I wonder if it's because my tray was a lower price ranged impulse purchase. It may be to get a decent nonstick coating you have to pay for it.

Mine are non-stick but I still use banking paper so I don't have to clean them. It's the best way.

It's scrubbing off the dried on crap that fucks them. Non-stick is a con on anything but saucepans honestly.

Non-stick coatings are made from a plastic called PTFE. It is almost completely inert below about 250°C and is widely used in medical devices and the chemicals industry for this reason - it just doesn't want to react with anything. Unfortunately it's also very soft and the non-stick properties mean that it's difficult to adhere it to metal.

It's totally harmless unless you massively overheat it, but it's also inherently fragile. Avoid using metal implements or scourers.
