@DisplacedTexan I think the sealcoat is a month or two old. I know not to use a degreaser but I have nothing to lose because if it doesn’t come off I’m having it sealcoated again anyway. I was hoping a degreaser would be aggressive enough. It didn’t appear to effect the asphault or the sealcoat. I even brushed it and nothing. The stain looked less obvious when I keft so hopefully she is happy.
How much is a sealcoat? Internet says about .25 a sq ft. That seems pretty cheap.
