Nope, definitely not crazy as I do the same thing on the practice green before a round - wipe off any moisture, grass or sand (if they have been doing maintenance work) on both the putter and ballI realize I am a bit of a crazy person as it relates to practice and wiping my clubs down after each shot - but it's just my routine.
Hell, I even take a towel with me to the putting green on dewy mornings to wipe the balls down after each set of putts, since they pick up sand. I just absolutely love the look of a fresh face on a club. Makes me feel good.
If the practice mats are wet at the nets where I warm up, I will have a towel with me to wipe down the face of the clubs after each shot as well
