How To Remove Hard Water Spots From Your Auto Glass

If nothing else works, its time for the big gun – wheel acid. This usually contains hydrofluoric acid, which is highly corrosive, as its intended to clean thick brake dust deposits which are strongly basic.

A word of warning: As it reacts to the mineral deposits, the acid will neutralize and release toxic gasses right into your face. You want to be using this product in a well-ventilated area with full protection equipment – gloves, eyewear, and a respirator.

Hydrofluoric acid is too strong to use in pure form. It will eat through the clear coat and base layer, attacking the metal directly. Make sure its diluted 1 to 4 with distilled water. Always spot test in a less visible area first to make sure its not too aggressive on your clear coat.

You also dont want to use it on bare metal wheels, as it will quickly corrode aluminum, chrome, and steel.

Dont spray directly onto the car. The acid is highly corrosive to glass, rubber, and plastic trim, so you dont want any overspray.

Instead, spray the solution into your microfiber tower, then quickly work it into the mineral deposits. Leave it on for just a few seconds before wiping it away with a clean towel and rinsing the panel thoroughly with water.

Examine the surface and apply it in the remaining troubled spots. Then, wash the panel again thoroughly to remove all acid traces. You dont want this to sit on your paint a second longer than necessary.

Regardless as to whether you hand wash and polish your ride by hand, take it to a professional detailer, or merely hit the touchless car wash down the street, a quick scrub and rinse goes a long way aesthetically.

But there are some side-effects to washing a vehicle, one of them being unsightly water spots.

    How To Remove Water Spots From Car Windows With Vinegar Or Lemon Juice

    Vinegar has always been a well-known window cleaner. because most water spot crystals are alkaline, the acid will dissolve them as well as cause them to dissolve.


    • White vinegar
    • Purified water
    • Paper towels, squeegee, or a cloth towel


  • Fill the spray bottle halfway with pure water and halfway with white distilled vinegar . After filling the bottle, shake it for a few seconds to mix the solution.
  • Spray the diluted vinegar solution onto the water spots. Allow the vinegar to soak in for 1 to 2 minutes.
  • Try to gently rub the spots away. If you scrub the glass too vigorously you risk scratching it. The acids in the vinegar should be doing most of the work to break down the hard water minerals and release their bond to the glass.
  • If you have stubborn water spots, leave the solution on the glass for a bit longer and try again. Re-apply it as needed and be sure to not allow the vinegar solution to dry onto the window surface.
  • Clean with the vinegar/water mixture car glass with a squeegee, towel, or a paper towel. Before you start cleaning the mixture off for the final details, make sure the glass is damp.
  • When youre finished it is a good idea to clean the glass one last time with a good glass cleaner. My best recommendation is Invisible Glass Glass Cleaner.
