How to Remove CFW/Oil From Vinyl Siding

If you have vinyl siding on your house that becomes stained with oil or CFW, "calcofluor white," a fluorescent white stain, you may find that removing the oil or CFW is difficult. Because of their chemical makeups, these stains are not easy to remove from any surface. You can use a pressure washer, but this may not completely remove the CFW or oil. Another method is to use household cleaning products and a little bit of elbow grease.
