Any wet clothing from a victim should be air dried before it is packaged

True.

Explanation:

Wet or moist evidence which is collected from  a crime scene, can be stored in  containers made up of plastic  and transported it back to an area from where these evidence received, if the time of storage in plastic is 2 hours or less and this is done to prevent the other evidence contamination.

Wet evidence which is packaged in paper or in plastic, should be removed and allowed it to  air dry completely.

Repackaging of that evidence must be done in a new and dry paper container because the moisture will allows the  microorganisms growth that can alter or destroy the  evidence.
