Corrosion can have devastating consequences on vehicle components, leading to premature wear, damage, and even failure. When it comes to brake systems, corrosion can compromise safety, leading to brake failure and potentially catastrophic accidents. As such, it is crucial to understand the corrosive properties of brake cleaners and take necessary precautions to minimize their impact.
What You Need to Know About Brake Cleaner Corrosion
In this article, we will delve into the world of brake cleaners, exploring the factors that contribute to their corrosive nature, the risks associated with their use, and most importantly, how to choose and use brake cleaners safely and effectively. Whether you’re a seasoned mechanic or a DIY enthusiast, understanding the corrosive properties of brake cleaners is essential for ensuring the integrity of your vehicle’s brake system and staying safe on the road.
Is Brake Cleaner Corrosive?
Brake cleaner is a widely used solvent-based cleaning agent designed to remove dirt, grime, and brake fluid residue from brake components. However, there is a growing concern about the potential corrosive properties of brake cleaners, which can have devastating effects on metal surfaces, human health, and the environment. In this article, we will delve into the world of brake cleaners, exploring their composition, corrosive properties, and potential risks associated with their use.
Composition of Brake Cleaners
Brake cleaners typically consist of a mixture of solvents, such as hydrocarbons, chlorinated hydrocarbons, and alcohols. These solvents are designed to dissolve and remove grease, oil, and other contaminants from brake components. However, some brake cleaners may also contain additives, such as corrosion inhibitors, to enhance their cleaning performance.
The most common solvents used in brake cleaners include:
- Tetrachloroethylene (PCE)
- Trichloroethylene (TCE)
- Methylene chloride
- Acetone
- Toluene
- Xylene
These solvents can be classified into three categories: (See Also: What Do New Brake Pads Cost)
- Chlorinated solvents: These solvents contain chlorine atoms, which can react with metal surfaces, leading to corrosion.
- Hydrocarbon solvents: These solvents are derived from petroleum and can be less corrosive than chlorinated solvents.
- Polar solvents: These solvents, such as acetone and methanol, are capable of dissolving a wide range of contaminants and can be less corrosive than chlorinated solvents.
Corrosive Properties of Brake Cleaners
Brake cleaners can exhibit corrosive properties due to the presence of aggressive solvents, which can react with metal surfaces, leading to corrosion. The corrosive properties of brake cleaners can be attributed to several factors:
- pH level: Brake cleaners can have a low pH level, making them acidic and increasing their corrosive potential.
- Reactivity: Some solvents in brake cleaners can react with metal surfaces, leading to the formation of corrosive compounds.
- Surface tension: The surface tension of brake cleaners can affect their ability to penetrate and corrode metal surfaces.
The corrosive properties of brake cleaners can lead to:
- Rusting and corrosion of metal surfaces
- Deterioration of brake components, such as brake pads and rotors
- Reduced braking performance and safety risks
- Respiratory problems: Inhaling brake cleaner fumes can cause respiratory irritation, asthma, and other breathing difficulties.
- Neurological effects: Exposure to brake cleaners can cause headaches, dizziness, and nausea.
- Skin and eye irritation: Direct contact with brake cleaners can cause skin irritation, burns, and eye damage.
- Air pollution: VOCs and HAPs in brake cleaners can contribute to air pollution and climate change.
- Water pollution: Improper disposal of brake cleaners can contaminate water sources and harm aquatic life.
- Soil pollution: Brake cleaners can contaminate soil and groundwater, posing long-term environmental risks.
- Rusting and corrosion of brake components
- Deterioration of metal surfaces, such as brake rotors and drums
- Reduced braking performance and safety risks
- Water-based brake cleaners: These cleaners use water as a solvent, reducing the risk of corrosion and environmental pollution.
- Biodegradable brake cleaners: These cleaners are made from natural, biodegradable ingredients, reducing their environmental impact.
- Non-chlorinated brake cleaners: These cleaners do not contain chlorinated solvents, reducing their corrosive potential.
- Always read the label and follow the manufacturer’s instructions.
- Wear protective gear, including gloves, safety glasses, and a face mask.
- Use brake cleaners in a well-ventilated area, away from open flames and sparks.
- Avoid spraying brake cleaners directly onto metal surfaces; instead, use a cloth or brush to apply the cleaner.
- Test the brake cleaner on a small, inconspicuous area before using it on the entire brake system.
- Dispose of brake cleaners and their containers according to local regulations and guidelines.
- The composition of brake cleaners and their corrosive properties
- The risks associated with brake cleaner use, including human health risks, environmental risks, and metal surface risks
- Safer alternatives to brake cleaners, such as water-based, biodegradable, and non-chlorinated cleaners
- Best practices for using brake cleaners, including wearing protective gear, following manufacturer’s instructions, and disposing of brake cleaners properly

Frequently Asked Questions: Is Brake Cleaner Corrosive?
What makes brake cleaner corrosive?
Brake cleaner can be corrosive due to the presence of solvents such as trichloroethylene, perchloroethylene, and methylene chloride. These solvents can dissolve and remove grease, grime, and brake fluid residue, but they can also damage certain materials, including paint, plastics, and metals, if not used properly.
Can I use brake cleaner on all types of brakes?
No, not all brake cleaners are suitable for all types of brakes. Some brake cleaners are specifically designed for use on disc brakes, while others are intended for drum brakes. Using the wrong type of brake cleaner can damage the brake components or leave residue that affects brake performance. Always check the product label or consult with a mechanic if you’re unsure.
