 ## Storage and cleaning
-...
+After recovery and once all caibrations are done, clean the sensor and remove any biofouling. The following protocol is recommended by SeaBird for the Wetlabs EcoPUCK:
+
+1. Remove the protective copper plate, if present.
+2. To clean the optics head use soap and water with a non abrasive pad.
+3. If necessary, a wooden scraper can be used to push the material from the optics area.
+4. Rinse very well with clean water and dry carefully.
+5. Do not use any strong solvent (ie. acetone or MEK) which could ruin the epoxy head of the sensor
