Thanks for the info Tank, I haven't soaked it in vinegar, i soak it in fresh water then rinse in saltwater then take my readings, and i do verify that there are no air bubbles on the arm. I'll try the vinegar trick when i take my next reading. I'll really be able to verify it's accuracy when i get the refractometer, I'll order it sometime today.
