Amaphaneli ensimbi engagqwali, njengezinye izinto zokwakha ezivezwe emoyeni, angaba ngcolile. Izindlela zokuhlanza ezivamile zimi kanje:

Okokuqala, uthuli olungaphezulu nokungcola okunensipho ebuthakathaka yokugcoba kanye nokugeza kwamanzi afudumele.Ilebula, ifilimu ngamanzi afudumele kanye nenani elincane le-detergent yokugeza.Izithako zokunamathisela zisebenzisa utshwala noma i-organic solvent scrub.

Okwesibili, amafutha angaphezulu, amafutha, ukungcola kwamafutha okugcoba, ahlanzekile ngendwangu ethambile, nge-detergent engathathi hlangothi noma isixazululo se-ammonia noma i-detergent ekhethekile yokugeza.

Okwesithathu, ingaphezulu lensimbi engagqwali linemigqa yothingo, kubangelwa ukusetshenziswa ngokweqile komshini wokuhlanza noma uwoyela, ukugeza ngamanzi afudumele ukugeza hlangothi kungenziwa washed.Stainless steel surface ukungcola okubangelwa ukugqwala, kungaba 10% nitric acid noma ukugaya okokuhlanza ukuwasha, futhi ingasetshenziswa ukugeza okukhethekile izidakamizwa.
