CS511-L Dissolved Oxygen Probe 

5.  To clean, immerse the top part of the sensor in distilled white vinegar (3% 

acetic acid) for about 30 min.  If vinegar is unavailable, use a soft 
toothbrush, automatic dishwasher detergent, and clean water to clean the 
cathode, anode, and plastic.  Rinse all components thoroughly with clean 
water after cleaning (see FIGURE 8-3).
