The capacitors could be oil-filled, hence the 'goo' they'd squirt. Said
oil might be nasty and carcinogenic, mind you. (PCBs)
But 100uF is rather high for it to be a non-electrolytic.
I thought the basic structure of the AC electrolytics
was that of
two matched DC electrolytics wired in series. If this is true,
then I suppose a current limited AC supply might be able to reform
them?

I doubt if a motor capacitor is made up out of a back-to-back
electrolytic pair. Usually, motor capacitors are some form of 'oil
filled' capacitor or modern variant, and are non-polarized. Usually
not of a high enough value to need to be an electrolytic design.
