Strange, unwashable milky stain
Hey, as the title states, I have this odd stain on the ( dont know how to explain it) side pillar of the car. kind of where the windscreen finishes on the right hand side of the car. It's this odd milky looking stain. Its not white white, more of a very light greyish colour. No matter what i do. I cannot wash it off. I've tried everything so far that I can think of?
Any ideas?
It's not a raised stain. When you run your finger across it it doesn't feel like there is anything there. Sort of like an oil mark. I dont park under any trees so I don't think its sap.
did aliens do this to my car? its only about 4x4cm so its not huge. but its just always there.
