I’m trying to mention the safer alternatives every time. Because no one wants to damage their top-notch coaster hubs or rotors with the wrong product.

However, before cleaning the rotors, clean your disc brakes with mild soap and water. It’ll save the brake from getting infected by pads and rotors.

However, for the more instant effect, I would suggest using small brushes. Like a toothbrush or hand brush kit. My friend gave me some brushes last Christmas because I’m always anxious about my bike cleaning.

Long story short, I’m totally in love with these brushes. Because they rinse out even the tiniest bit of residue. So I texted him to give me the full information about the brushes. 

Here I’m listing them in the following table. Take a look-

However, if your bike’s disc rotor or brakes keep rusting, find out the reasons first. After that proceed to clean with accurate materials.

Frequently Asked Questions (FAQs)

Can I clean brake rotors with WD40?

No, you can’t clean brake rotors with WD40. Because this cleaner is strong and manufactured as a thin and soft product. So it’ll instantly burn off the discs. 

What can I apply as a brake grease alternative? 

You can apply silicone grease instead of brake grease. Because silicone grease can perform as effectively as brake grease. 

How do I prevent my rotors from impounding?  

You can spray in anti-seize lubricant in the center of the rotor hole. I always use the permatex lubricant. And it helps a lot!  

Last Words

Nonetheless, no matter what solvent you’re using as the cleaner, always wear gloves. Otherwise, you might accidentally burn your hands off. So, be extra careful!
