What are these gray stains on my white 2001 Honda Civic?

They have been there for quite some time, but a regular wash does not remove them. The surface is smooth and shiny, just like the paint, but it appears stained below the surface. Does anyone know what this is or how to fix it? Thank you

Try a light rubbing compound. If it is on the surface, that will removed it. Since it looks like it is caused by your windshield washer fluid it will probably come off.

Because of the location and the spray pattern that must have been caused by a wrong type of fluid being used in the screen washer bottle. Could now be impossible to remove but that is a guess as unless we know what caused it then it is impossible to say for sure.
