Yes, there are a few sensors that need to be stored properly in order to stay in good condition.
Oxygen Gas Sensors should be stored upright. This is easily done by storing them in the bottle in which they were shipped.
Dissolved Oxygen Probes (DO-BTA) should have the filling solution emptied and rinsed out, then stored dry.
Optical DO Probes should be stored in the humid environment of the storage bottles in which they are shipped. If the yellow sponge at the bottom of the storage bottle dries out, add a few drops of distilled water.
pH Sensors and Oxidation-Reduction Potential (ORP) Sensors should be stored vertically in the storage solution provided. The storage solution needs to be replaced once a year, and replacement solution can be purchased, if needed pH Storage Solution (PH-SS). If the solution looks cloudy before vacation, it is probably best to change it before you leave. This helps to prevent mold growth and ensures that the sensor is indeed stored in the proper solution.
The pH electrode I have been using no longer seems to work or is slow to respond. Is there anything I can do to fix it?

Ion Selective Electrodes should be stored in the humid environment of the storage bottles in which they are shipped. If the sponge at the bottom of the storage bottle dries out, simply add a few drops of distilled water.
Make sure no liquid (either in a cuvette or spilled) is inside a Colorimeter.
