+1. If you use good quality RO/DI and the unit isn't filthy, it should dry perfectly clean (i.e. no deposits.)

And to the OP, while it's noble to calibrate every time, it's probably not required. Once a month is probably fine. Try pointing at a bright light while you're taking the reading, and check to see if there's an adjustable focus on your instrument.
