Video: How to clean your Turtle Tough pH/ORP Sensor

Not sure how to properly clean your sensors? Our Cleaning Kit video tutorial will show you step by step, how to clean and provide optimal care for the sensing element and reference components of your Turtle Tough pH/ ORP sensor.


  • Brush for glass cleaning
  • 15% HCI cleaning solution bottle (125ml)
  • Glass cleaning polish bottle (50ml)
  • Conditioning solution for sensor storage and rejuvenation (50ml)
  • Beaker (100ml)
  • Scraper
  • Q-tips
  • Carry bucket


  1. Rinse the tip of the sensor in tap water.
  2. Gently scrub the reference with the nail brush to remove any fouling. If you can’t remove the fouling with the brush use the scraper to scrape away the top layer of the reference and expose fresh uncontaminated material. Be sure to avoid the glass element as scratching it will irreparably damage the sensor. 
  3. Once most of the fouling is removed, pour some of the HCI solution into the beaker and soak the tip of the sensor in the HCI for five to ten minutes. Rinse the tip thoroughly with DI water.
  4. Tap a small amount of the glass cleaning polish powder onto a hard surface and use a wet cotton bud to form a polishing paste. Gently polish the glass tip to remove any film oils or contaminants.
  5. After polishing, rinse the tip with the DI water and wipe clean using a lint-free cloth or chem wipes. (Not included)
  6. Soak the tip of the sensor in conditioning solution for at least ten minutes. Severely compromised sensors can even be soaked overnight to help rejuvenate the reference.
