Zotsatira za pickling ndi passivation pa prefabrication, kuwotcherera, kuyezetsa, ndi kutentha mankhwala adzachititsa okusayidi chitsulo, kuwotcherera slag, mafuta, ndi dothi zina kudziunjikira pa chitoliro (mpweya zitsulo chitoliro, mpweya mkuwa chitoliro, zosapanga dzimbiri chitoliro) , zomwe zidzachepetsa kukana kwa dzimbiri kwa chitoliro chachitsulo. Zosiyanasiyana. Pickling ndi mankhwala njira kuchotsa dzimbiri: kuchepetsa asidi dzimbiri kuchotsa makamaka amachotsa zitsulo oxides pamwamba pa zitsulo zosapanga dzimbiri mapaipi ndi mpweya. Pazitsulo zachitsulo, makamaka amatanthauza iron oxide, yomwe imakhudzidwa ndi zitsulo zachitsulo izi ndikuzisungunula mu asidi kuti akwaniritse cholinga chochotsa dzimbiri. Musanachotse pickling ndi dzimbiri, mafuta omwe ali pakhoma la chitoliro chosapanga dzimbiri ayenera kuchotsedwa poyamba, chifukwa kukhalapo kwa mafuta kumalepheretsa madzi otsekemera kuti asagwirizane ndi khoma la chitoliro chachitsulo. Zimakhudza mphamvu yochotsa dzimbiri. Mapaipi opanda mafuta (monga mapaipi azitsulo zosapanga dzimbiri a oxygen) ayenera kuchotsedwa mafuta kaye. Pickling amatanthauza kugwiritsa ntchito pickling solutions monga sulfuric acid kutsuka oxide wosanjikiza ndi fumbi pa workpiece. Phosphating ndi njira yothandizira kuyeretsa pamwamba.
