I have a problem with a haze/cloud that has formed on the back of the plastic covering my readouts (speedometer, tach,gas, ect). I gave my sister my keys to get a cd out of my car and for some reason she rolled down the window and never rolled it back up. It rained overnight and when I woke the next morning the haze had formed on my plastic. I figured it would go away but it's been a month and it's still there. Is there anyway to make it go away without pulling the dash off? WIll it clean off or will I have to replace the cover? The car is a 1997 Infiniti I30.
