Whether you are a vehicle owner or are looking to buy a car and want to maintain it, you have come to the right place.

Will Vinegar Ruin the Car Paint if Used as a Cleaning Agent?

Vinegar will ruin the car paint if used improperly as a cleaning agent. Its high acidity levels can damage the clear protective coat on the paint and discolor or peel off the paint from the car’s surface. Its acidic pH makes it a risky car-cleaning liquid.

Vinegar is a commonly used product for most of us. We use it for several purposes, such as a cleaning agent for our hair and skin or in various foods to enhance the taste.

Vinegar contains acetic acid, leading to its acidic nature. The acidity level varies in different types of vinegar but generally has a pH level of around 2 to 3. This pH indicates it is highly acidic, making it harmful to the paint.

So, if you’re wondering, is vinegar safe for car paint, or will vinegar ruin paint on walls of the car? Vinegar does harm as the acid in it tends to dull or discolor and scratch the car’s surface.

Its acidic nature will attack the clear coat and make the paint look dull. It can lead to scratches on the car as it does not provide the same lubrication as other car cleaning agents like car shampoo.

Similarly, using a mixture of baking soda and vinegar on car paint is quite risky due to the abrasive nature of these substances.

How Do You Make a Safe Vinegar Mix for the Car Paint?

You can make a safe vinegar mixture for the car paint, but it is still risky. Mix one part of vinegar and nine parts of water and use it to clean the car’s surface. With the help of a cloth, you can gently wipe away the stains.

Earlier in this article, we answered the question, “Does vinegar damage car paint?” and the answer is yes. So, can you use vinegar to clean car exterior? You can use vinegar to clean the outside of the car without damaging the paint.

You will need one part of vinegar and nine parts of water, and pour this mixture into a spray bottle. Apply this mixture of water and white vinegar on car paint and gently use a sponge or cloth to clean the dirty surface.

Don’t entirely cover the car in the acid; do this slowly and carefully. When finished, rinse the car’s surface with cold water and then dry it completely using a dry microfibre cloth.

The next step is optional but recommended. Use some car wax or sealant as a protective coating for the car’s paint to maintain its shine.

We use a small amount of vinegar to dilute it in a lot of water to avoid causing any damage due to its acidity. Using this method, you can remove water spots from the car’s surface.

It will also help prevent a frozen windshield in the winter. Window cleaners can be pretty expensive, so this is a good alternative.

Here are the steps to clean the interior with this mixture:

  1. First, prepare the mixture by adding equal volumes of white vinegar and water in a spray bottle. If your car is filthy, there is another more potent recipe: distilled water, white vinegar, baby oil, and dish soap. You can add a few drops of essential oil to this mixture for a pleasant car smell.
  2. Test this on the less visible areas first to ensure that the solution is not damaging to the car interior.
  3. Spray this vinegar solution on a cloth and wipe dirty surfaces like the windows, dashboard, and upholstery, including the materials that cover the seats, headrests, and other interior surfaces where you sit or come into contact.
  4. Use a brush or cloth to wipe off the dirt and stains, and once you are done, use a damp cloth to wipe away the vinegar and dirt.
  5. Take your time to dry each spot where you used vinegar to prevent odor, and leave your car doors open afterward to let the vinegar smell disperse.
