Brake parts advice follow-up

Some regular length pipe cleaners will probably work too.
Could just double a small length at the end as the "swab".

Or wad up a small section of cut cloth and twist it on tightly at the end of the pipe cleaner.

Or tie 2 pipe cleaners together.

Some creativity and ingenuity will clean these things up almost as new.   The problem is getting back into the segmented section, behind the small slit wall ... and then getting into all 4  corners and the wall itself.  Got the front part OK at least.

Yeh thats the fun part, and where the pipe cleaners work the magic.
Bend as needed.

I don't think any amount of soaking for any length of time under a month with any type of product will do it for you. I tried everything from lacquer thinner to Brake-Kleen and many things in between.

The pipe cleaners with brake fluid were like a magic wand and fairy dust.

Wife   wound up doing a fairly good job using 409 Commercial Degreaser cleaner from Lowes.  With a little bit usage of the pipe cleaner like you suggested, she did a good job of getting about 95% of the crud off.  Satisfies me at least; not so ugly as before.

I wouldn't use the master cylinder after you put gas in it.

it takes almost no petroleum products to expand the seals in the brake system.
Almost certainly got some gas in the master cylinder.
 
At the very least I would pull it apart and rinse it out and inspect it.. wouldn't want to send that gas through the rest of the system.
When you pull the rear wheel cylinders: take them apart and put gas on half the seal, remove it right away,.. see what happens.
 The gas has been in the master cylinder for quite awhile now, I'm guessing at the very least it will need a rebuild kit with new seals.

Brake cleaner is what gets used in a brake system.

You asked this a day or so ago ... and I responded ... NO gas was used in the M/C ... just the reservoir (made of hard plastic) after I had removed it from the MC.
