How do I remove hard water spots from my car?

Hard Water Stain Removal from Car Exterior

To remove hard water stains on your car, try rinsing your car with white vinegar, using a solution of 3 parts soft water to 1 part white vinegar, increasing the vinegar content as needed. Be careful to only wash your car in the shade, or in the evening, as the sun will dry the water quickly and cause more spots. You may also want to try using crumpled newspaper for polishing your car, as it will leave a nice shine and prevent spots. You may want to treat your car with a commercial product, such as Rain-X to stop the stains from returning.

Rain-X's main ingredient is rubbing alcohol! Cheaper to buy that.

Rain-X chemically modifies the surface of the glass to become hydrophobic (water beads up and runs off). Rubbing alcohol certainly won't do that.

Are you referring to hard water stains on the paint?? Newspaper won't scratch?? I also thought Rain-X was just for windows.

Don't ever use newspaper to polish your car. It will damage the paint by leaving swirl marks, which are small scratches. Use a chamois or microfiber towel. Pure cotton towel or diaper also works.

Rain-x on a painted surface is asking for trouble. If you ever have to have paint work done, the body shop is going to be pissed because the paint wont stick. They will have to strip the car to bare metal. I doubt the Insurance company is going to pay for the extra labor. Guess who will be stuck with the extra labor charge. Unless you are a pro, never use anything that its not made specifically for an automobiles finish. Chances are you will do more harm than good.

Micro cloth on paint and glass after washing is what the pros use, especially on chrome.

Polishing your car with crumple newspaper will eventually scratch your car
