I just found my car 4 wheel brake disc have become rusty . Why it will happen? How to remove it? Is that a big problem ?

 

Normal, they are cast iron, exposure to the elements will cause surface rust. Drive it and they will clean off.

 

Wow , I didnt drive my car for 1 week . So I will drive it tomorrow. I hope it really will clean off after I drive it, Thank you for your reply.

 

This is completely normal and just driving a bit, using the brakes will clean the rust off. It's nothing to be concerned about in the least.

 

All right , Thank you for your reply

 

You're welcome!

 

It doesn't have to sit a week to rust either. You'll notice it after hours in some climates.

 

Like the Sauna we call Florida!

 

 

And when it returns, which it will, you won't be concerned about it.

 

 

Go to an auto parts store and get a good chrome cleaner.

 

do you have any good chrome cleaner to suggest me?

 

Mothers or Maguires both make excellent chrome cleaner/polisher.

 

Can I use those product every time when I wash my car? If chrome become blur then I use this cleaner to clean it ?

 

If you dry your car immediately after washing it, you won't need to use a cleaner for your chrome.

 

But the chrome showing in picture as you can see. That is haze on it, I cant wash it . Only that part is happening this.

 

Likely because you haven't dried the chrome thoroughly after washing your car. If you need to use a chrome cleaner it's fine to do so. Or you can just try using a cloth soaked in vinegar and see if that does the trick.

 

Will vinegar destroy the chrome or paint? If that work I will try it tomorrow

 

Try it on a place not too conspicuous and see, but it should not harm the paint or chrome.

 

Ok, I will try it , thank you
