Hello, I purchased one of the cheap yellow pH pens from Amazon and also purchased some blue lab storage solution. I purchase the storage solution because somebody mentioned something about storing pens submerged in that solution to keep the tips good. After I read the instructions on the yellow pen it says to dry it off before storage. What do you guys think is best? Get a can of compressed air and blow it off each time or store it in this bluelab storage solution?
