How to remove oil stains from painted Hardie Siding?

I recently had a new roof installed. During the demo of the old roof, the idiots did not pay attention and as they were throwing the old shingles to the ground, some hit my house and left tar marks. I have cleaned these areas with WD-40. In some spots, there appears to be an oil stain. I'm thinking I left the WD-40 on too long.

Dawn dish washing liquid. Honest! Allow a solution on the stains a bit then rinse off with a hose.How to remove oil stains from painted Hardie Siding?
Um, why would you use WD-40 to clean with? Anyway, I assume it is flat paint, and you can't get the oil stains off. You need to seal the stain in with an oil based primer and repaint it.





Goof off is oil based and will leave oil stains. Anything you use to remove the oil stains, will damage the paint.
You may want to try a product called Goof Off. It usually will remove paint, oil, tar or most any stain. Apply it, let it set for a few minutes then remove with a scrub brush and rinse the siding.
