Mike and Group No rubbing , No scrubbing, I got the brown stains out of my dash with suntan cream. Just rub a little on the dash and let it sit in the shade for a while. Then in a day or two rub a little more on. Mine went away in a day or two. Please report back and let me know how it worked for you. P.S. Use a damp cloth. My $0.02's worth John
