Grease stains on my back porch- how to get it out?

I have a screened back porch and my grill is on it. My husband spilled oil on it and it has stained the salt treated boards. I have tried using Dawn and pressure washing. I want to use a clear stain and wonder if it will be able to penetrate the wood thru the oil stain

    You could try covering the stained area with cat litter or plain cornmeal. Either one will probably absorb the oil and reduce the stain. It might take more than one treatment, though.

    When I was a child, my mom used Fuller's Earth to remove grease stains from some surfaces. Look at HD, Lowes, and Ace websites to see if is still available.
