Dear Pyotr,
In the days before I built 5" gauge live steam ,I played with
HO railways. If I remember correctly Brake fluid was used to strip the
paint off commercial plastic locomotive body shells prior to re-painting
in a different livery. the plastic was left undamaged
Regards Ian

Before I discard the old brake fluid, is it useful for anything around
the shop? BTW, what's in brake fluid?

From my young years (early 50's), I was taught that it was made from alcohol
and castor oil. You can smell the alcohol----not sure about the castor
oil, but it makes sense.

Back in those days ...
