I have just recently caught the bug and now I am fairly obsessed with keeping my car (2007 Mercedes ML500) clean and protected. But I found myself doing something that may be a bit extreme. I am particularly finicky right now over my windshield and the other day I left the house and got a few blocks away and noticed a smudge. I actually pulled over, got out a microfiber and a small spray bottle and cleaned it up before continuing. I am not OCD in any other area of my life, so this surprised me! Has anyone else done this?
