I bought some new pizza screens for use in my conveyor oven, but pizza keeps sticking to them. What is the problem?

Before using new pizza screens, you need to spray them (make sure it's an oil-based spray) and run them through the conveyor about 8 to 10 times, until they get dark in color. This will coat them well and essentially give them a non-stick coat. The other important thing you need to know is not to wash them. If a pizza sticks to the screen, you need to run the screen through the oven and burn it off. You can brush the screens to clean them, and if you need to wash them for some reason, give them another light coating of spray and run them through the oven again.
