I washed my bike yesterday and noticed white-gray stains on my engine guard (one side only). I did research and realized that it was hard water spots caused my minerals dried onto the paint during hot and sunny days. I realized that I had got sprayed while a business was watering their grass on my way to work at 4:30am yesterday and that since it sat on my bike all day while it was hot and sunny that it stained. I tried washing it off but no avail. I read that I can get rid of the hard water spots but it takes time (which I don't have a lot of). I was wondering if anyone makes a wipe or chemical to help speed up the process.
