Following advice for obtaining tce brake parts cleaner was obtained.

It containes TCE but the TCE is tetrachloroethylene as opposed to trichloroethylene.

Brake parts cleaner and japan drier were mixed for the Orange I/II fix extraction. No word yet on the result but just curious if this is a viable solution? Has anyone used brake parts cleaner or tetra to extract?

Tetrachloroethylene or
Perchloroethylene are what you want
to look for.  Swim has not used the jd/tce mix, but has successfully used the tce as a stand alone, on some white 60's that are orange gakked, but not orangeII gakked.

swumn uses tetra to perform the fastest, most cleanest fb extract ever from reds,120's, or 240's. look at posts by ahgreich.

Why do the polymers re-gather?

What were the test results of the other chlorinated solvents?
Why was trichlorethylene deemed unsuitable?

Why are combinations of perchlorethylene and others unsuitable, is it just a case of potency or do you think it solvates pseudo?

DCM removes PEG(s), I'm pretty sure about this.
I think a combination of TCE+DCM or DCM + hexane is excellent in theory.
