Ko te hangarau horoi taiaho e pā ana ki te whakamahinga o ngā hihi taiaho kaha-teitei hei whakamārama i te mata o te mea mahi, kia kore ai e puta te paru, te waikura, te paninga rānei i runga i te mata. Ka mimiti, ka tihore rānei te paparanga, ā, ka tere te tango i te piri o te mata, te paninga rānei o te mea horoi, kia ma ai te tukanga. He hangarau hou tēnei e hangai ana ki te pānga taunekeneke i waenga i te taiaho me te rauemi, he rerekē i te tikanga horoi miihini tuku iho, te tikanga horoi matū me te tikanga horoi ultrasonic (tukanga horoi mākū), kāore e hiahiatia he whakarewa CFC pakaru hei whakaiti i te paparanga ozone, kāore he parahanga, kāore he haruru, kāore he kino ki te tinana tangata me te taiao.
