Kungakhathaliseki ukuthi hlobo luni lwemishini yemishini, ukuvimbela amanzi kuyindaba okufanele inakwe.Okufanayo kuyiqiniso ngemishini yokugcwalisa i-polyurethane.Le mishini ikhiqizwa ngokuphehla ugesi.Uma amanzi engena, ngeke nje abangele ukusebenza okuvamile, kodwa futhi anciphise impilo yomshini.

1. Gqoka izinto zokuzivikela lapho uhlanganisa izixazululo ezimbili zesitoko;
2. Ukungena komoya okuhle nokuhlanzeka endaweni yokusebenza;
3. Uma izinga lokushisa le-ambient liphezulu kakhulu, lizokwenza ukuthi uketshezi luhwamuke futhi kuzoba nengcindezi.Ngalesi sikhathi, ikhava yokukhipha kufanele ivulwe kuqala, bese kuthi ikhava yomgqomo ivulwe ngemuva kokukhishwa kwegesi;
4. Uma umshini okhipha amagwebu we-polyurethane unezidingo zokunqanda ilangabi legwebu, kufanele kusetshenziswe i-additive flame retardant;
5. Ingxenye kumele ibe yingcweti ohlelweni lokukhihliza amagwebu ngesandla;
6. Lapho isikhumba sethu sithintana ngokuqondile nesisombululo sokuqala, kufanele sisigeze ngensipho namanzi ngokushesha.Uma ixhumene ne-B, kufanele siyisule ngokushesha ngekotini yezokwelapha, siyihlanza ngamanzi imizuzu engu-15, bese siyigeza ngensipho noma ngotshwala.
