I have noticed really nasty milky stains (looks like water spots but all over the trims and it looks milky)on all the chrome trims around the windows of my S90. I tried few solutions including some metal polish solutions and none was helpful. The other chrome trims e.g. in the front of the car are super shiny and in order, is just with the trims around the windows. Has anybody an idea what the material of these trims is? Any ideas how to fix that? I googled and there were bunch of crazy solutions with other cars but first I would love to know what the material is. Is it aluminum, aluminum with plastic film, real chrome or plastic. Thank you in advance for your tips. BTW, I will post pictures as soon as I get a good lighting to make the damage visible.
