Liquid crystals stored in vials and bottles are often found to degrade with time, trapping more and more ion impurity in the materials. Here we report on our identification of a major source causing such degradation and illustrate how the electrical properties of an old batch of liquid crystal can be restored by a regenerative agent. This approach, which is demonstrated to be quite efficient, entails simply soaking the agent in the liquid crystal.
