Hi Hugh,
From where you've placed this posting I assume you have Pentax scopes and keep them in your equipment library. Am I right ?
If so, how does the library cope with cleaning the scopes and how do you transport "dirty" ones back to the library after use.
If the users clean and disinfect them, how do you make sure they are "sterile" when you send them out from the library ?

Today is the day you worried about yesterday - and all is well !
