Rusty brake discs

[Bulutt]

My Mustang brake discs rust up within minutes of getting wet when I wash the car but my Audi discs never rust at all. Does Audi use a better grade of steel or what?

You got fancy brakes on the Audi? Their rotors rust just like any other car

Rusty rotors that shower your freshly cleaned wheels the very second you next apply the brakes...............................a conundrum that has annoyed car enthusiasts and detailers for eons. Very frustrating and most noticeable on black or dark colored wheels.

The old prevention for this situation was to drive forward and backwards several times to dry out the rotors. Time consuming and a display that will certainly have the neighbors perplexed.

However, there are two products that can help reduce or eliminate this issue.

Hydes Serum Rustopper - for brake rotors (detailingshed.com.au)
BILT HAMBER ATOM MAC corrosion inhibitor (detailingshed.com.au)

Rust Inhibitor For Cars | Hyde's Serum Rustopper | Obsessed Garage
Bilt Hamber Atom-Mac | Rust Prevention | Obsessed Garage

These two are used and work in the same way. After you finish cleaning each wheel, spray the product onto the rotor, be somewhat generous to ensure even coverage. For best results, I apply it again after the final rinse and before drying the car. A leaf blower will help dry them out a bit quicker, which also helps. Both are safe for your wheel finish should it drip from the rotor onto the wheel.

The Atom Mac appears expensive, but is dilutable, so a 500ml bottle will take you a long way.

Why am I not surprised that DBF5.0 provided good solutions. Thanks for your contributions to our site, DBF.

Hello; I watch TV shows about cars. Some are essentially long format ads. Frome time to time I see a crew replacing rotors they claim are coated which prevents that surface rust. I cannot say for sure as i have not tried them. But apparently they exist.

I can see surface rust on my rotors soon after a caw wash. A way to reduce this is to drive the car around a bit after a wash. This also allows the wind to help dry out the nooks and crannies.

Could be the Audi has coated rotors.

I still use the drive once around the block trick after a wash myself. I do have the Hydes but have a really hard time getting it applied properly without making another mess on the barrels of my wheels that I have to clean up :(

As for the Audi rotors, maybe they are Carbon Fiber? I know Audi makes some high end cars

Leaf blower then after I’m done drying the car I take it around the block. Usually does the trick

I do the same. After doing my regular wash job I drive around my area applying the brakes to dry them. Has worked for years. Worst thing is to leave them wet and rusting, in my opinion. I don't know about other chemicals to spray on to help the process as I have never used them.

This is the perfect excuse to buy carbon ceramic rotors. If the wife/gf asks about the missing 15 grand, tell them it was all about cleaning, and making sure the car always looks good when they are driving…… *cough*. Oh and safety. Don’t forget to work that in somehow.

At the end of the wash my Audi has a tiny bit of rust on the rotors so I was wrong to suggest it had no rust but it is barely visible. The Mustang rotors on the other hand are super rusty before I even finish half the wash. The problem really is that the rust comes off as soon as I drive and so my black wheels end up with brown rust dust all over them.

Hello; The rotors on my car get surface rust quickly. I learned years ago to not use the parking brake if the car will sit for a day or two if I drive it into the garage when it is raining. I park it with the trans in gear. The pads will rust enough to bind the pads a bit. Breaks loose with a pop which sounds bad.
Must be different materials in the two cars. You likely can get upgraded rotors & pads for the Ford.

It's all iron content. The Audi rotors must be pretty low. Unfortunately, my detailing ritual includes a lap around the block to get all the rust off, then I finish up the wheel detail.

Different iron quantities affect rust rates. These are iron discs so they’ll all rust eventually. Check out any car dealer lot after a few days of rain lol.

I have an inclined driveway so I just drag the brakes up and down a couple times after drying the car. Works every time.
