Master cylinder repair

So, I bought a new master cylinder for my '37 115c. Then I painted it, put it on my frame, and it sat outside for about a month while I was finishing the chassis. The cap was on.

The problem is, I forgot that the cap is vented, so some water got in and the inside is rusty. I have never put fluid in the master cylinder.

My thought was to disassemble it, inspect the bore, clean as required, and reassemble, but I don't know what to do about the rest of the master cylinder interior.

Any thoughts on how to clean the rest of the master cylinder?
