Will Brake Cleaner Remove Rust?

Last Updated on October 6, 2023 by Matthew Lloyd

Yes, brake cleaners can remove rust from brake rotors. To effectively remove rust, spray brake cleaner onto the rusted area, allow it to penetrate for a few minutes, and then scrub the surface with a steel sponge or brush. Wipe off the surface and finish with a final coat of brake cleaner. However, if the rust buildup is substantial or bonded to the surface, the effectiveness of brake cleaner may be limited. Regular maintenance and rust prevention are key to ensuring the longevity and optimal performance of your vehicle’s braking system.

Purpose of Brake Cleaner

Brake cleaner is a powerful degreaser and cleaner for metallic surfaces and parts. Its primary purposes include:

• Removing resins, dust, tar, fats, and oils deposited on vehicles.
• Providing effective cleaning for brake discs, the underfloor of motors, and engine compartments of motor vehicles.
• Acting as a specialized cleaning agent for brake systems, including linings, drums, pads, brake shoes, and caliper units.

How Does Brake Cleaner Remove Rust?

Brake cleaner is a highly effective solution for removing rust from metal surfaces, including brake rotors. When used correctly, it can help restore the appearance and functionality of the metal. Here is a detailed explanation of how brake cleaner works to remove rust:

1. Spray brake cleaner: Start by spraying the brake cleaner directly onto the rusted metal surface. Please make sure that the area is well-ventilated to avoid inhaling any fumes.
2. Use a tray for runoff: Place a tray or container underneath the metal surface to catch any runoff or overspray from the brake cleaner. This helps prevent any spills on the floor or surrounding areas.
3. Allow penetration: Allow the brake cleaner to penetrate the rust for a few minutes. This allows the cleaning solution to work into the rust and loosen its grip on the metal.
4. Apply more brake cleaner if needed: If the rust is stubborn and doesn’t come off easily, apply more brake cleaner to the affected area. This ensures thorough coverage and helps break down the rust further.
5. Scrub with a steel sponge or brush: To actively remove the rust, use a steel sponge or brush to scrub the affected area. The abrasive nature of the steel sponge or brush helps dislodge the rust particles from the metal surface.
6. Wipe off the surface: After scrubbing, use a clean cloth to wipe off the surface. This removes any remaining rust particles and ensures a clean and smooth finish.
7. Please ensure no oil residue: It is important to ensure no oil residue remains on the surface after cleaning. This can be done using a clean cloth to remove excess brake cleaner or oil.
8. Apply the final coat of brake cleaner: To leave the metal surface clean and rust-free, apply a final coat of brake cleaner. This helps to remove any remaining traces of rust and leaves a protective layer on the metal surface.

Chemicals in Brake Cleaners and Their Efficacy in Rust Removal

There are two types of brake cleaners available: chlorinated and non-chlorinated. Each type contains different chemicals and offers varying levels of effectiveness.

Chlorinated brake cleaners:

• Contains tetrachloroethylene as the main ingredient, facilitating the removal of brake dust, rust, brake fluid, grease, and oil.
• Utilizes carbon dioxide as a fuel.
• Non-flammable but harsh to the skin.

Non-chlorinated brake cleaners:

• • Contains heptane and acetone to remove contaminants that are not water-soluble.
  • Utilizes carbon dioxide as a fuel.
  • Highly flammable but less harsh on the skin.

Both types of brake cleaners are effective in removing loose rust. However, their effectiveness may be limited to substantial rust buildup or bonded rust.

The Benefits Of Brake Cleaners

Brake cleaner offers several benefits, making it a valuable tool for maintaining your vehicle’s braking system and other metallic parts:

• Easy application, energy-conserving, and time-effective.
• Minimal preparation is required, reducing the need for an extensive workforce.
• Improves overall brake function and performance.
• Prolongs the life of brake pads and discs.
• Rapidly removes oil, brake fluid, grease, and grime.
• Reduces brake squeals and treats them effectively.
• Acts as a rehydrating formula, preserving braking components.
• Helps identify leaking vacuum hoses in petrol engines.
• Versatile for cleaning other metallic parts of vehicles.
• Useful as an engine degreaser and oil stain remover.
• Applicable for home use in cleaning concrete, surfaces, and stubborn stains.

The Disadvantages of Brake Cleaners

While brake cleaner offers numerous advantages, it also has some disadvantages to consider:

• Contains toxic compounds and should not be used indoors or in poorly ventilated areas.
• Some brake cleaners are flammable and require proper storage in controlled temperatures.
• Skin contact with brake cleaner can cause irritation or injury.
• Chlorinated brake cleaners can react with high temperatures or strong ultraviolet light, posing risks of choking or asphyxiation.
• Brake cleaners may decompose certain plastics or rubber materials, causing them to become brittle and fracture over time.

Alternatives to Brake Cleaner for Rust Removal

WD-40 Multi-Use Product:

This Product is another option for rust removal. It was initially used in the aerospace industry to prevent rusting and offers the following benefits:

• Effectively removes rust from iron, chrome, and stainless steel.
• Non-damaging to the metal surface or paint.
• Widely available and easy to use.

Evapo-Rust Super Safe Rust Remover:

Another excellent rust remover is Evapo-Rust Super Safe Rust Remover, a nontoxic option suitable for various surfaces. Its advantages include:

• Effectively dissolves rust on auto parts, hardware, tools, cookware, and antiques.
• Comes in a large 1-gallon container, offering long-lasting usage.

Conclusion

Brake cleaner serves as an effective solution for removing rust from various metal surfaces, including brake components. By understanding how to use brake cleaner properly, you can restore the performance and safety of your car’s braking system. However, it’s essential to consider the advantages and disadvantages of brake cleaners and explore alternative rust removal options based on your specific needs. Regular maintenance and rust prevention will help ensure your vehicle’s brakes’ longevity and optimal functioning.
