Is brake cleaner a degreaser? Yes, brake cleaner is a powerful type of degreaser specifically formulated to remove oil, grease, and brake dust from braking components.
In the realm of automotive maintenance, the terms “brake cleaner” and “degreaser” are often used interchangeably. However, knowing their differences is important for ensuring the longevity and safety of your vehicle’s components. This in-depth guide delves into the specifics of brake cleaners and degreasers, exploring their compositions, uses, and the distinctions that set them apart.

What Is Brake Cleaner?
Brake cleaner is a specialized solvent designed to remove brake fluid, grease, oil, and other contaminants from braking components. Its primary function is to ensure that brake parts are free from substances that could impair their performance. Brake cleaners are typically available in aerosol cans for easy application.
Composition of Brake Cleaners
Brake cleaners are formulated with a combination of solvents that allow them to quickly dissolve oils and grease. Common ingredients include:
- Acetone: A powerful solvent that evaporates quickly, leaving no residue.
- Methyl Acetate: A solvent that provides high solvency to oils and grease and has a desirable drying rate.
- Hydrocarbons: Such as heptane or toluene, which assist in dissolving contaminants.
- Chlorinated Solvents: Like perchloroethylene, which are used in some formulations for their effective cleaning properties but are less common due to environmental and health concerns.
Types of Brake Cleaners
Brake cleaners are categorized based on their solvent composition:
- Chlorinated Brake Cleaners: Contain perchloroethylene and are effective in cleaning but pose health and environmental risks.
- Non-Chlorinated Brake Cleaners: Use solvents like acetone and are considered safer for both the user and the environment.
What Is a Degreaser?
A degreaser is a cleaning agent designed to remove grease, oils, and other heavy contaminants from various surfaces. Unlike brake cleaners, degreasers are used for a broader range of applications, including engine components, machinery, and tools.
Composition of Degreasers
Degreasers often contain a mix of:
- Alkaline Solutions: Such as sodium hydroxide, which break down grease and oils.
- Solvents: Like kerosene or mineral spirits, which dissolve oily substances.
- Surfactants: That help emulsify oils and grease, making them easier to remove.
Types of Degreasers
Degreasers are available in various forms:
- Water-Based Degreasers: Safer for the user and the environment but may require more time to act.
- Solvent-Based Degreasers: More aggressive in removing heavy grease but can be hazardous to health and materials.
Key Differences Between Brake Cleaner vs Engine Degreaser
Here is a table of difference between brake cleaner and engine degreaser –
| Feature | Brake Cleaner | Degreaser |
|---|---|---|
| Primary Use | Cleaning brake components | Removing grease and oils from various surfaces |
| Evaporation Rate | Fast | Slower |
| Residue | Leaves minimal to no residue | May leave a residue depending on formulation |
| Surface Compatibility | Safe for metal brake parts | May not be suitable for all surfaces |
| Health and Safety | Varies; some formulations contain harmful chemicals | Varies; some may be less toxic |
When to Use Brake Cleaner vs. Degreaser
Here’s a detailed comparison to help you understand when to use brake cleaner vs. degreaser, depending on your task:
Use Brake Cleaner When:
- Cleaning brake components like pads, rotors, and calipers.
- You need a fast-drying solution that leaves minimal residue.
- Working with metal parts where residue could impair performance.
Use Degreaser When:
- Cleaning engine components, tools, or machinery.
- You require a solution that can break down heavy grease and oils.
- Working with surfaces that are not sensitive to residues.
Safety Considerations
Both brake cleaners and degreasers contain chemicals that can be hazardous to health. It’s essential to:
- Use these products in well-ventilated areas.
- Wear appropriate personal protective equipment, such as gloves and safety glasses.
- Follow the manufacturer’s instructions and safety data sheets.
Frequently Asked Questions
Here are some FAQs about brake cleaner –
1. Can I use brake cleaner to clean engine parts?
While brake cleaner can remove grease and oil, it’s not formulated for engine components. Using it on engines may not provide the necessary cleaning and could damage sensitive parts.
2. Is brake cleaner safe for plastic components?
Brake cleaners, especially those with chlorinated solvents, can damage plastic parts. Always check the product label for compatibility with plastics.
3. Can I use degreaser on brake components?
Degreasers are not recommended for brake components as they may leave residues that can impair braking performance.
4. Are non-chlorinated brake cleaners safer?
Non-chlorinated brake cleaners are generally safer for both the user and the environment, as they do not contain harmful chlorinated solvents.
5. Can I use brake cleaner on painted surfaces?
Brake cleaners damage paint. It’s best to avoid using them on painted surfaces unless the product is specifically labeled as safe for such use.
Conclusion
Knowledge about the differences between brake cleaners and degreasers is crucial for effective and safe vehicle maintenance. By selecting the appropriate product for the task at hand, you can ensure optimal performance and longevity of the vehicle’s components.
