    John V. has it. Reforming is only applicable to electrolytic capacitors – and not at all useful for paper, film and foil types.

    A good rule -of -thumb: If the cap is under 1uF in value, it’s of the latter type and cannot be reformed. If it’s over 1uF in value and has polarity markings, it’s a potential candidate for reforming.
