Season a screen - What would be the best method

Hi,
I wish to use screens to load my pizza’s into the deck oven, for the same i have noticed that pizzeria’s have a dark almost black coating on their screens, mine are silver aluminium screens.
i have read somewhere that it is advisable to “season” the screens before use.
Can anyone provide a correct method to season the screens effectively for Deck oven use.

Thanks so much, went through the thread, thanks again
