Nutrient salts and organic films coat pH electrodes and slow their response. Hanna's general purpose cleaning solution dissolves those deposits: soak the electrode for 15 to 20 minutes, rinse, and recalibrate. Regular cleaning is the cheapest way to extend electrode life and keep readings honest. 120 mL bottle.
