there is a product you can buy in stores. It guarantees that it will lift off the fog of anything on your car. The best thing to do would be to go to a place like advanced auto, or the nearest auto detail-er shop, and see what they have on their shelves. I bought something last year that made the fog go away, and never come back. Ask the employees of the store, they should be able to show you the product. May God Bless.
