Asphalt cleaning help

How would you guys go about doing this driveway?
After researching, from what I know is your not supposed to use any bleach or degreaser (harsh chemicals) on asphalt. So how would I get out these stains? I’m assuming it’s rust, if it is f9 barc is what I read helps but Just rinsing asphalt (the whole driveway) won’t help clean it. Any help is appreciated.
