Summary
Conditioning and cleaning a Fluoride ISE
Answer
Yes, gently rub the tip of the electrode with fluoride toothpaste free of whiteners and abrasives in a circular motion with your thumb. Rinse well with deionized (DI) water, and soak in isopropyl alcohol (IPA) for 30 minutes. After that rinse well with DI water and condition for about 30 minutes in the lowest standard of the calibration step.
