 === How to clean the wedge ===
-min in the ultrasonic bath in ISO-Propanol FIXME
+If the wedge is clogged, you might want to clean it.
+Find a small petridish and fill it with a bit of isopropanol. Hold the petridish underneath the wedge without spilling, and use the Test-switch to turn ultrasounds on. This way, we basically ultrasonicate the wedge as if it were in a ultrasonicator. Sometimes, 10 seconds is enough to clean the wedge. If it is still clogged, you might want to remove it. Please contact a technician before you do that.
