Indlela yokugcina
1. Imithetho yesitoreji Gcina endaweni epholile, nengena umoya. Gcina kude nomlilo nemithombo yokushisa. Gcina isitsha sivalwe ngokuqinile. Kufanele igcinwe ngokuhlukana nama-acids, ama-halogen, namakhemikhali adliwayo, futhi igweme ukugcinwa okuxubile. Ifakwe izinhlobonhlobo ezifanele kanye nenani lamathuluzi omlilo. Indawo yokugcina impahla kufanele ifakwe izinto zokwelashwa eziphuthumayo ezivuzayo kanye nezinto ezifanele zokugcina.

2. Yavalwa futhi yapakishwa ezigubhu zensimbi, 180kg isigubhu ngasinye. Gcina endaweni epholile futhi enomoya. Gcina futhi uthuthe ngokuhambisana nemithethonqubo yezinto ezivuthayo nezinobuthi.

Inhloso eyinhloko
