What's the trick for using both sides of a double-sided griddle?

[Sukhoi]

It's not so bad when the ridges are against the burner and you're cooking on the flat side. But it seems like whenever I do it the other way the burner cooks the seasoning right off the flat side. Is there any way around this?

No, you have to re season it each time.
