For a few months now my roommate has been getting huge blisters on his hands and fingers that leave scars. His hands look like something out of a monster movie. We were trying to figure out what we bought that might be causing it. We realized we had bought a new type of dish liquid at the dollar store. I think it was Sun brand and it was antibacterial. I looked it up and the "antibacterial" ingredient was a pesticide. We stopped using it and the blisters stopped. We switched back to Ajax. A couple of weeks ago the blisters started again and won't stop forming. He went to his doctor and he didn't know what it was but gave him cortosone ceam and some type of patches called Tegaderm Film. It's not working. Two more blisters this morning. What's weird is that they seem to form overnight when he's sleeping. I looked up the ingredients in Ajax and it contains sulfuric acid! And other chemicals that are harmful. The pdf said not to come in contact with skin. Then how the heck do you wash dishes??? Is there any SAFE brand out there? He's obcessive about washing dishes. If there is even on dish or piece of flatware he has to wash it.
