M'makampani opanga zombo, njira zamakina monga fosholo pamanja, kuphulitsa kuwombera, kuphulika kwa mchenga, madzi othamanga kwambiri komanso ma jets abrasive amagwiritsidwa ntchito makamaka kuchotsa zokutira zakale. Komabe, zitsulo zotayidwa, makina njira zosavuta zikande zotayidwa, choncho chachikulu Gwiritsani sandpaper kupukuta, utoto stripper, etc. kuchotsa akale utoto filimu. Poyerekeza ndi mchenga, kugwiritsa ntchito utoto wochotsa utoto kuti achotse filimu yakale ya utoto ali ndi ubwino wa chitetezo, chitetezo cha chilengedwe komanso kuchita bwino kwambiri.

Ubwino wogwiritsa ntchito chochotsera utoto ndikuchita bwino kwambiri, kugwiritsa ntchito kutentha kwa chipinda, kutsika pang'ono mpaka chitsulo, kumanga kosavuta, kusafunikira kuwonjezera zida, komanso kuipa kwake ndikuti zochotsa utoto zina zimakhala zapoizoni, zosasunthika, zoyaka, komanso zokwera mtengo. M’zaka zaposachedwapa, mitundu yatsopano yochotsera utoto yatulukira, ndipo zochotsera utoto zokhala ndi madzi zapangidwanso. Kuchotsa utoto kumakulitsidwa mosalekeza, ndipo ntchito yoteteza zachilengedwe yasinthidwa mosalekeza. Zinthu zopanda poizoni, zopanda poizoni, komanso zosapsa pang'onopang'ono zalowa msika waukulu wa zochotsa utoto.
