Will Ketchup Ruin My Car’s Paint?

Ketchup ruining car paint will depend on the color of the car paint, how long the ketchup has been on the car, and how much ketchup was on the car.

Typically, if you get a bit of ketchup on your car paint but remove the ketchup immediately, your car paint may not change at all.

However, leaving ketchup on car paint for a longer period could potentially ruin the car paint, particularly in the area where the ketchup was.

Almost all types of ketchup are acidic because ketchup contains vinegar and tomatoes, and ketchup usually has a pH level of 3.9.

Ketchup is not so acidic that ketchup would immediately ruin paint, but ketchup’s acid can slowly make car paint deteriorate if the ketchup is left on the car paint.

Moreover, the acidity of the ketchup will degrade car paint faster if the car is under the sun or is hot because heat makes acid particles move faster, speeding up the deterioration process.

Additionally, lighter car paint colors like white, light blue, etc. may be more susceptible to getting stained from ketchup since ketchup is deep red.

Plus, ketchup has a higher likely hood of creating noticeable damage on car paint if you have a lot of ketchup on your car paint.

However, if the ketchup is only on your car paint for a few minutes, it is highly unlikely that ketchup will ruin your car paint.

What Foods Ruin Car Paint?

Other than foods, other food products that can ruin car paint are coffee and soda, and soda and coffee can ruin car paint the same way ketchup can ruin car paint.

If you spill coffee or soda on your car and wipe it off immediately, it is unlikely to cause any damage to car paint.

Generally, coffee has a pH level of 4.85 to 5.10 while soda has a pH level of 2.5 to 3.3 with coffee being slightly less acidic than soda.

Based on the acidity levels, soda is more acidic than ketchup and coffee are the least acidic of the three.

However, all three of these foods can damage car paint if you allow them to sit on the car paint for too long.

Moreover, soda will likely be the most damaging food product to car paint since soda is the most acidic, so soda will likely create noticeable damage in the fastest time.
