Ko nga taapiri e whakamahia nuitia ana ko nga papa me nga kowhatu. Ka taea hoki te whakamahi hei awhina rere mo nga kapene, te whakaheke me te whakahinuhinu mo nga raau taero kanohi, he whakarewa-tahi mo nga werohanga, he whakamarara mo nga whakaritenga wai, me te whakapumau mo nga whaariki me nga raau taero wera. Ka taea hoki te whakahiato i te povidone me te iodine povidone iodine (PVP-I) waipatu.
