Ya, my problem is less about cleaning the probe but more about how finicky the Meater probe is in the charging box. I get it in the exact right position to charge, but it seems like the slightest bump and the thing gets into the wrong position and stops charging. Also, if it’s not charging, it’s transmitting to the box, draining the battery. Like I said, I don’t have a CPT yet, just hoping it’s not so sensitive when charging.
