In designing applications that may lie dormant for extended periods of time, moderate voltage de-rating of devices is recommended , in order to provide an improved margin of safety against this effect.  Use of products specifically designed to be robust against degradation in storage is also suggested.
In repair/recommisioning situations, the generally prescribed treatment for atrophied aluminum electrolytic capacitors is to apply the system voltage gradually, over a period of 4-8 hours. Before so doing, verify that the equipment will not be damaged by a prolonged period of operation at below-spec supply voltages.

Aluminum Electrolytic capacitors with this designation are designed for continuous-duty, high-ripple applications such as variable-speed motor drives , and inverter applications.

...

This designation is associated with aluminum electrolytic capacitors which use a solid conductive polymer as an electrolyte material, rather than a liquid electrolyte. Typically , they exhibit better stability, lower ESR, and better lifetimes at elevated temperature than comparable liquid electrolyte devices, though availability is constrained to relatively low capacitance and voltage ratings , and the cost of devices for a given capacitance and voltage rating is significantly higher than a similar liquid electrolyte type.
