I am cleaning my bathroom cupboard, and had everything in a box. Now, putting things back, when I touch the inside of the box, or the things that are inside the box, my hand/fingers immediately turn white and become intensely itchy. When I rinse my hands with water vigorously and dry them off, the white spots vanish, and the itch diminishes or goes away completely. I am rinsing everything off now, and wearing chemical gloves, but what could be causing this reaction (so I know to avoid it, and maybe eliminate it completely from my bathroom)?
