Hi My guess is that crystals are more sensitive to moisture than the alternators…. The level of “clean” you need in a precision crystal enclosure is way beyond what is required in a number of other areas. One layer of water molecules is way to much in a modern crystal. can and do use crystals as detectors of low levels of “stuff” for this very reason.
