Indlela yokugcina
1. Izilumkiso zokugcina Gcina kwindawo epholileyo nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Gcina isitya sivaliwe ngokuqinileyo. Kufuneka igcinwe ngokwahlukileyo kwi-acids, i-halogens, kunye neekhemikhali ezidliwayo, kwaye ugweme ukugcinwa okuxubileyo. Ixhotyiswe ngeentlobo ezifanelekileyo kunye nobuninzi bezixhobo zomlilo. Indawo yokugcina kufuneka ixhotyiswe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokugcina.

2. Itywinwe kwaye ipakishwe kwimigqomo yentsimbi, i-180kg igubu ngalinye. Gcina kwindawo epholileyo nengena umoya. Gcina kunye nokuthutha ngokuhambelana nemimiselo yezinto ezinokutsha kunye netyhefu.
