Uboya bezimpawu eziluhlaza okwesibhakabhaka uthola umbala ojulile uma kuhlanzwa ngamazambane aqoshiwe.
Ukuhlwitha izinto ngejezi yeboya, engeza isipuni se-baking soda emanzini. Izovuselela umbala womkhiqizo, ukuqeda iphunga lokuthuthumela. Uma usula izinto zobusika zasebusika, engeza isipuni se-glycerin emanzini ngesikhathi sokugcoba kokugcina - azoba lula.
Ukugcina umkhiqizo oboshiwe uphelela futhi uhlanza, emva kokuwasha kufanele uhlanjululwe emanzini afudumele ngokufaka i-glycerin (isipuni ngamalitha amabili amanzi), bese - ngokubandayo ngesilinganiso esifanayo samamoniya.Ukuze ubuyisele ukubukeka kwasekuqaleni kwesirazi esikhukhulayo, kungenzeka ukuwageza emanzini, lapho amahora ambalwa khona ubhontshisi obunzima. Ijezi ligezwa emanzini afudumele, kancane liphihliwe futhi limile, isakazeka, ngokwesibonelo, ethawula.
