The importance of brake cleaning cannot be overstated. Brake systems are a critical component of any vehicle, and keeping them clean and free of debris is essential for ensuring safe and reliable operation. One of the most common methods of cleaning brake components is by using a brake cleaner, which is a solvent-based product designed to dissolve and remove grease, grime, and other contaminants from brake parts. However, with so many different types of brake cleaners on the market, it’s essential to understand the properties and potential hazards of each one, particularly when it comes to flammability.
Chlorinated brake cleaners are a popular choice among mechanics and DIY enthusiasts due to their effectiveness and ease of use. However, some users have raised concerns about the flammability of these products, which can be a serious safety issue if not handled properly. In this article, we’ll delve into the world of chlorinated brake cleaners and explore the question: is chlorinated brake cleaner flammable?

The Chemistry of Chlorinated Brake Cleaners
Chlorinated brake cleaners are typically composed of a mixture of solvents, including chlorinated hydrocarbons, aliphatic hydrocarbons, and aromatic hydrocarbons. The most common chlorinated solvent used in brake cleaners is trichloroethylene (TCE), which is a highly effective degreaser and solvent. However, TCE is also a known fire hazard and has been linked to serious health problems, including cancer and neurological damage.
Other common ingredients in chlorinated brake cleaners include mineral spirits, acetone, and toluene. These solvents work together to break down and dissolve grease, grime, and other contaminants, making it easier to clean brake components. However, the combination of these solvents can also create a flammable mixture that can ignite easily.
The Flammability of Chlorinated Brake Cleaners
Chlorinated brake cleaners are considered flammable due to the presence of volatile organic compounds (VOCs) and the potential for ignition sources. When a chlorinated brake cleaner is used, the solvents can evaporate quickly, creating a flammable mixture that can ignite easily. This is particularly true when the cleaner is used in a confined space, such as a garage or workshop, where oxygen is limited.
The National Fire Protection Association (NFPA) has established guidelines for the safe handling and use of flammable liquids, including chlorinated brake cleaners. According to the NFPA, chlorinated brake cleaners are classified as Class I flammable liquids, which means they can ignite easily and burn rapidly. This classification is based on the flash point of the cleaner, which is the lowest temperature at which the cleaner can ignite.
Flash Points and Ignition Sources
The flash point of a chlorinated brake cleaner is an important factor in determining its flammability. The flash point is the lowest temperature at which the cleaner can ignite, and it is typically measured in degrees Fahrenheit (°F). For example, a chlorinated brake cleaner with a flash point of 100°F (38°C) is more flammable than one with a flash point of 200°F (93°C). (See Also: How Long to Break in Brake Pads?

Ignition sources can also play a critical role in the flammability of chlorinated brake cleaners. Common ignition sources include sparks, flames, and hot surfaces. When a chlorinated brake cleaner is used, it is essential to ensure that there are no ignition sources present, such as open flames or sparks, to reduce the risk of fire.
Safety Precautions for Using Chlorinated Brake Cleaners
While chlorinated brake cleaners can be effective for cleaning brake components, they also present a number of safety risks, including flammability. To minimize the risk of fire and other accidents, it is essential to follow proper safety precautions when using these products.
Personal Protective Equipment (PPE)
When using a chlorinated brake cleaner, it is essential to wear personal protective equipment (PPE) to prevent exposure to the solvents. PPE may include gloves, safety glasses, and a face mask. These items can help prevent skin contact, eye irritation, and inhalation of the solvents.
Ventilation and Oxygen Supply
Good ventilation is essential when using a chlorinated brake cleaner to prevent the buildup of vapors and reduce the risk of inhalation. It is also important to ensure that there is a sufficient supply of oxygen in the workspace to prevent the buildup of flammable vapors.
Electrical Equipment and Ignition Sources
When using a chlorinated brake cleaner, it is essential to ensure that there are no ignition sources present, such as electrical equipment or open flames. This can help prevent accidental ignition of the cleaner and reduce the risk of fire.
Alternatives to Chlorinated Brake Cleaners
While chlorinated brake cleaners are effective for cleaning brake components, they also present a number of safety risks, including flammability. For these reasons, many mechanics and DIY enthusiasts are turning to alternative brake cleaners that are safer and more environmentally friendly. (See Also: How to Check Brake Fluid Mazda 6?

Water-Based Brake Cleaners
Water-based brake cleaners are a popular alternative to chlorinated brake cleaners. These cleaners are typically composed of a mixture of water and surfactants, which work together to break down and dissolve grease and grime. Water-based cleaners are safer and more environmentally friendly than chlorinated cleaners, and they are also less likely to ignite.
Silicone-Based Brake Cleaners
Silicone-based brake cleaners are another alternative to chlorinated cleaners. These cleaners are typically composed of a mixture of silicone and solvents, which work together to break down and dissolve grease and grime. Silicone-based cleaners are safer and more environmentally friendly than chlorinated cleaners, and they are also less likely to ignite.
Conclusion
Chlorinated brake cleaners are a popular choice among mechanics and DIY enthusiasts due to their effectiveness and ease of use. However, these products also present a number of safety risks, including flammability. To minimize the risk of fire and other accidents, it is essential to follow proper safety precautions when using these products, including wearing personal protective equipment, ensuring good ventilation, and avoiding ignition sources. For those looking for a safer and more environmentally friendly alternative, water-based and silicone-based brake cleaners are a popular choice.
