I just brought this 2003 Honda accord ​​​​​.I seen this on my alternator and around that area.???????

 

Looks like oil m8. Mines doing the same thing, got a small oil leak somewhere and its kind of spraying all in that general area. Notice is after driving it on the highway. I clean it off, and a week later it starts to creep back. Not a pro but see if you are losing oil after a while, if not it's maybe some other grease from somewhere. cheers.
