My vehicle is rather light in color being a light gold color. I had leaves on my vehicle and they were wet because it had rained during the night, but they blew off when I was on my way to work. When I went to get in the car to come home from work yesterday, I noticed they had left some stains on top of the car. I washed it on the way home and used a chamois but there are still some faint marks left. What do I use to get these off?
