Why wheel cleaner causes brake disc rust?

[Klasse Act]

I'll just drive my car!

In all seriousness, typically just pulling my car into the garage after a good wash and lightly riding the brakes will clean the rotor faces of any surface rust. I had no idea a product like this existed. If you do apply this product in the driveway and then pull the vehicle into the garage, I wonder how much of the product will remain on the rotors.

Well, when your low on wheel cleaner give P&S Brake Buster a try, can't hurt because it's inexpensive

They sell a product at automotive paint supply houses that gives short term protection against rust. I don't have any anymore and don't remember the name. It was for prepped metal that you weren't going to paint for a day or two. But, it lasted longer than a day or two.

Most good rust removers do the same thing. But, would be expensive for this type of usage.

I'm using K2 Roton Pro. It gives bleeding effect.



I heard that this type of cleaners are not good idea for using every week. I also heard that this should be used few times in a year only for very dirty wheels. For daily washing I should get less aggresive cleaner. Rust from rotors will be gone after drving but what about brake caliper, wheel nuts, wheel hub and other parts?

I think I will try with Brake Buster.

So my final question is Does aggressive wheel cleaner causes rust in the same level as normal water? I think wheel cleaner causes rust much faster but I need to test that on some parts.

Are those parts actually rusting? All of the cars I've owned for quite a while had aluminum or some form of alloy brake calipers. The unpainted ones would get brake dust embedded in them, but they wouldn't rust. Lug nuts and studs tend to be a non-rusting metal and sometimes painted/coated too because you don't want them to rust on the wheel and not be able to get them off.

I have had rust form on my hubs which made getting the wheels off difficult when I rotated my summer/winter wheels. The solution I found there was to take a wire brush to the hubs and brush off most of the surface rust. Once that was complete, I use a small dab of dialectic grease around the surface of the hub where the wheel touches. I also put a very thin layer on the wheel where it touches the hub. This keeps those areas from rusting together or the types of metals from bonding together. It doesn't prevent other areas of the hubs from rusting, but I does keep it from making the wheels hard to remove.

Exposed steel parts will rust in contact with moisture. Unfortunately there is no real way to keep it from happening unless the car never gets wet.

{Disclaimer:
Perhaps the below information will help.}

1.) Here is the OSHA Standard for determining
the metal rusting (corrosiveness) factor at the
Level 1 category:

2.) According to the Roton Pro wheel cleaning
product’s SDS…it can be corrosive; and meets
the above Level 1 category standard:

cleaner. I encourage you to look it over at
your earliest convenience.

One more question. It is also deironzier that should remove micro rust particles form car paint. How is it that it removes rust from car paint and causes it on other places?

paint and causes it on other places?

•First off:
-Metal corrosion/rust is a form
of metal oxidation.


•Then, to address your question:
-One is a material that will not undergo
metal oxidation (that is: unless it has
‘metallic chips’ sandwiched somewhere
between its film layers—then there’s the
possibility of those ‘chips’ oxidizing if,
or when, they’re exposed.);

-The other ones are materials that will
undergo metal oxidation.
