I use as hot of water as I can stand to rinse before arms enter the tank. I can feel my hands slicken up from the oils being rinsed away. My skimmer prefers this method. I don't suffer from dry hands though but I can see your plight. I use liquid detergent and wish they made concentrated dry detergent since I inevitably get the liquid on my hands. If a coral falls it has to wait until I can't smell the perfume on my hands. Justin, I'm glad you mentioned the metals in antipersperants.... I had no clue.
