How brake fluid damages the car paint?

You might wonder about how the brake fluid, an essential component of your car, can damage its shine. Brake fluid typically contains chemicals that can damage car paint if it comes into contact with the painted surfaces. The main culprits are the glycol ethers present in some types of brake fluid. These molecules perform a dual function, which makes the fluid effective at damaging coatings. The chemical reaction of glycol works similar to an aggressive solvent on the car paint, causing discoloration, fading, or even peeling.

The fluid breaks the coating layer leaving vertical marks or stripes while moving downwards on the car body.  Additionally, brake fluid is often a highly corrosive substance, especially if it contains moisture or becomes contaminated over time. Corrosion can eat away at the paint and cause damage to the underlying metal surfaces. If brake fluid leaks or spills onto the car’s paint, it should be cleaned up promptly to minimize the risk of damage.
