Use a brake cleaner spray to clean the brake rotors without removing the wheel. Spray the cleaner directly onto the rotor surface, focusing on areas with heavy dirt or debris. After letting it sit for a short while, remove it with a fresh cloth.
2. Wire Brush:
To get rid of any accumulated rust or dust, lightly scrub the brake rotor surface with a wire brush. Be careful not to damage the rotor, and ensure that you only brush in one direction.
3. Sandpaper:
If there are stubborn deposits on your brake rotors, you can use fine-grit sandpaper (around 400-600 grit) to scrub away the surface corrosion and contaminants. Again, be cautious not to score or gouge the rotor during this process.
4. Rubbing Alcohol/Ethanol:
Dampen a clean cloth with rubbing alcohol or ethanol and wipe down the brake rotors' surface. This will help dissolve and remove any oil or grease residues on the rotors, ensuring better performance.
5. Vinegar Solution:
Mix equal parts of water and white vinegar in a spray bottle. Spray this solution generously onto the brake rotors' surface and allow it to soak for a few minutes before wiping it clean with a cloth. White vinegar helps break down tough grime and rust without causing damage.
6. Compressed Air:
If you have access to compressed air, blow away loose dirt and debris from the brake rotor's surface using an air compressor nozzle attachment. This can be an effective way of removing loose particles that might interfere with braking performance.
