A while back I stuck my hand into a bucket filled with iodophor treated water after sanitizing a few things, and there was some stinging on couple small wounds I had. A friend assures me that the pain wasn't caused by the iodophor, and that iodophor does not cause pain when applied to an open wound. Is this true, or should I be worried (about pain) about sticking body parts with cuts in iodophor treated water?
