Greg - Your Car Angel shows the easiest way to remove hard water stains on a car. Calcium buildup and lime are found in all hard water systems and getting it off car windows and car paint is difficult unless you have the best product.
Shown are:
Lime Away
Vinegar
Dish washing liquid
CLR
Bar Keepers Friend
Hard Water Stain Remover
You can use polishing compound and a buffer to get a final professional look, but Lime Away is the easiest to use and least expensive.
