Can I Use Acetone to Clean Brakes?

When dealing with automotive maintenance, brake cleaner is a go-to product for cleaning debris and contaminants from brake components. However, some enthusiasts might wonder about the possibility of using acetone as an alternative cleaning method. In this article, we explore the pros and cons of using acetone to clean brakes, and provide guidance on best practices to ensure your vehicle's braking system remains in optimal condition.

Introduction to Brake Cleaner

If you need to clean the brakes, it is highly recommended to use a can of brake cleaner. Brake cleaner is specifically formulated to dissolve oils, grease, and other contaminants without damaging rubber or plastic parts. It is also designed to evaporate quickly, minimizing the risk of inhaling its fumes.

Why Clean the Brakes?

Spraying brake cleaner is often necessary when there has been an accidental oil or grease spill. If the brake components are soaked in oil or grease, they should be replaced. In any case, the area where the spill occurred should be thoroughly cleaned to ensure optimal performance and safety.

Alternatives and Risks

If you are hesitant to use brake cleaner, it is perfectly acceptable to try alternatives. For instance, many mechanics prefer to use bras rotor cleaner or even a homemade solution. However, it is crucial to be cautious when using alternative solvents, as they can pose risks to rubber and plastic parts.

Acetone for Brake Cleaning

Acetone can be used to degrease metal surfaces, but it is not ideal for cleaning brake components. Wiping acetone on plastic or rubber-based components can cause them to degrade within weeks. In fact, acetone and other similar solvents like benzene, toluene, or xylene are excellent at dissolving fats and oils, making them useful for cleaning spilled brake fluid.

Understanding Solvents and Their Effects

Polar solvents, such as acetone, ethanol, methanol, and isopropanol, are commonly used in brake cleaners. These solvents have the advantage of effectively cleaning residue and contaminants. However, it is important to note that most highly dangerous or toxic substances used in brake cleaners have been prohibited, but the solvents are still harmful to rubber and plastic parts.

Safe Cleaning Practices

To ensure the longevity and safety of your brake components, it is recommended to follow these best practices:

Alkaline engine degreaser: Use an alkaline engine degreaser to remove oil and grease. This product is designed to break down tough, oily residues without damaging your components. Water rinse: After cleaning the components with an engine degreaser, rinse them with water to remove any remaining residue. PAD or shoe cleaning: If necessary, use paint thinner to clean the brake pads or shoes. Follow with a thorough dry wipe to remove any dirt. Avoid acetone: Acetone is not the best option for cleaning brake components. While it can be effective for degreasing, it can damage rubber and plastic parts. Always opt for products specifically designed for brake cleaning.

Conclusion

While it is possible to use acetone for degreasing, it is not recommended for cleaning brake components. Instead, rely on specific brake cleaning products that are formulated to safely and effectively clean your brakes without damaging surrounding parts. Proper maintenance of your brakes is crucial for your safety and the performance of your vehicle.
