I work in Patch-Clamp Recordings, this requires circulating ACSF (high Sodium-Chloride) through a chamber between the objective and condensor of a DIC microscope (Zeiss). Unfortunately, the chamber suffered a discrete leak and dripped through the condenser of the microscope without being noticed, before I went on vacation. Returning, I noticed that the lower lense is covered with cristallized salt - from the inside.
My question being: What is the most pragmatic approach to removing the salt without harming the lense, if there is one at all?
Thanks a bunch,
