Cleaned up my master cylinder today ..took about 30 min and some elbow grease.

 

Looks good, what did you use?

 

Gee that cap and bale turned out nice and shiny Great job on the master. I'm guessing something like CLR

 

Ok...I'll share my secret, but first, the master is an aftermarket swap I did over the summer ( and, yes, I kept the original to rebuild)😁 So getting the cap and bail shiny was easy..just some metal polish and elbow grease😁

As far as the master, it was mainly surface rust, so a wire brush took care of most of that. Then I sprayed it with WD40 and let it soak for a few minutes. Wiped it down, sprayed some WD40 on a cloth, and wiped it on, and that was that..easy peazy...now it's simply a matter of maintenance 😀

 

Wow, your humidity and heat down there are brutal on metal aren't they? I took a master off my car this past fall that was installed back 6 years ago, and it still looked like the one you cleaned up. Problem is it failed and was leaking from the piston end. Cheaper to replace than rebuild. Rockauto is good for that.
It looks just like the AC Delco one I put on.

 

Looks great.

 

I normally paint mine with cast paint so it stays looking like that.

 

That looks much better, I did the same w mine 2 years ago. Also got a slight case of the MAWs and bought the Eastwood MC paint. I was super happy w the paint went on nice and looks good. I'll post a pic when I get a chance.

 

Hmmmm, more I think about it, I like the 'patina' look better. Change it back. Just throw some clear on it and call it good.
