Capacitor Reforming
Reforming capacitors is only applicable if a device has not been used in a long time (as in years), and the capacitors are presumed good (or, put another way, "it ran when parked"). If you know that the device sat for a long time, then was powered on normally and and found not to work, the damage is likely permanent and any affected …

Electrolytic capacitor
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
Does an electrolytic capacitor degrade each time it receives reverse …
Time for it to get damaged depends on the reverse voltage applied, size of the capacitor and the material used for the dielectric and the electrodes. Generally when used in ac, most common application being the filter, I have not see capacitors sustaining damage sufficient enough to interfere with the operation.

Capacitor
A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store electrical energy temporarily in an electric field.The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e. an insulator that can store energy by becoming polarized).
