Hey guys I have a red hanna ph pen and I'm just wondering what you all do for cleaning the probe. I noticed some kind of algea buildup on the probe the other day. I sprayed it off with warm water, wiped with it clean and put back in glass of plain water. Since then I calibrated with the 7 and 4 point solution and all is good. So id like to hear what different people use for liquid to store the ph meter in and any ways of cleaning.
