If a endoscope is washed and you are sending it for sterilization, make sure the glass covers on the distal ends are dry and preferable rinsed with a cloth. This prevents residu from burning into the glas during sterilization.
It's a small thing to do but will extend the lifetime significantly.

Yes this helps a lot! Thanks!

In addition to the first post, use alcohol to clean the tip and ocular.
