Kunezinhlobo eziningi zengilazi, okuhlanganisa ingilazi evamile yokwakha, noma ingilazi ecutshungulwe futhi yasetshenziswa ezindaweni ezikhethekile. Izidingo zokuhlanza nokuhlanzeka kwengilazi nazo zihlukile. Namuhla sizokwethula umshini wokuhlanza ongahlanza ingilazi ebonakalayo.

Ngenxa yezici zayo, ingilazi ebonakalayo kumele ihlangabezane nezidingo zesithombe se-optical kanye nosayizi omncane, ngakho-ke kudingeka kufakwe amakhemikhali akhethekile ngesikhathi senqubo yokuhlanza ukuze kuncibilikiswe uthuli namabala ebusweni bengilazi, futhi kudingeka amanzi ahlanzekile ukuhlanza ingilazi. Imishini yokuhlanza ingilazi ebonakalayo ekhiqizwa yinkampani yethu isebenzisa isakhiwo esivundlile, ukuhlanza kwamazinga amathathu, futhi ifakwe amathangi amanzi amathathu. Igezwa nge-spray yokucindezela okuphezulu, ukugeza ngemithi, kanye namanzi ahlanzekile. Ngemva kwamasethi amabili okomisa, inqubo yokuhlanza ekugcineni iqediwe.
