Re: Engine oil stains on deck gelgoat
If the surface is porous it will be real hard to get out, you might try flushing with clean oil and blot. You might lift some out. And then wash with Dwan. Also, with time and sun it will weather away in a year. Once you clean it up the best you can you might try you color the spot with white...paint, shoe polish, something white and watered down just to get into the pores, just enough to get in there and tint it.
You could try to pressure washing it.
