Photo doesn’t clarify where on the machine are the streaks. Front panel? Regular stainless steel? Coated black stainless? Other type of finish?

It’s stainless steel and there are 4 lines running down in the photo

I don't know what might be on yours or what you could have tried already, but all I've used on mine - KitchenAid stainless about 10 mo old - is Weiman's stainless cleaner.

It seems to take off anything spilled or dripped so far, I really don't have to use it often. Maybe every couple of months? But no small children in the house. Soft clean rag, not paper towels. Good luck!
