Yeah dont touch the probe. Tap water in a glass is ok for brewday storage, then when youre done, rinse it with storage solution or distilled water, then store in recommended storage solution. Tap or distilled water or storage solution in a glass will keep the probe wet and neutral while you mash, allowing you to simply remove the probe, shake, and insert into your test liquid. Swirl in the glass to get the probe readeing a homogeneous solution, that should work fine. The probe should not be touched or dried at any time. The test liquid should be cooled from mash temps to room temp. I learned that this will extend the life of the probe as well as make one's readings more accurate.
Yeah proper ph does wonders for efficiency. Dont sweat a .1 ph discrepancy. At the end of the day thats a rounding error in the scheme of things.
