Okokuqala, ukubhekwa kokubukeka: ukuthunga ithawula kuhle, umphetho ucocekile, ububanzi buyaguquguquka, buvundlile futhi buqondile, alikhohlisi futhi alisontekile, ukuqina kuyavumelana, ukuphakama kwezinwele kuhlanzekile, indandatho yevelvet iqondile;Ithawula lesandla ezingeni lamehlo, indandatho yevelvet igqamile futhi ihlanzekile, ukuhlanzwa kwangaphandle kwe-lint engavamile kuhle.Umbala ocwebile ogqamile, ngaphandle kokujula kwento engalingani ube ngcono.
Okwesibili, ukuthinta ngesandla: ithawula likakotini elihle lizwakala lithambile, lithambile futhi lingenawo umuzwa obushelelezi.Bamba isibhakela esithambile futhi esinwebekayo, ungacishi ilinti.
Okwesithathu, iphunga: Amathawula amahle awanuki.Uma kukhona iphunga lekhandlela noma iphunga le-ammonia, libonisa ukuthambisa okuningi;Uma kukhona ukunambitheka okumuncu, inani le-PH lingase lidlule izinga;Uma kukhona ukunambitheka okubabayo, kusho ukuthi ukusetshenziswa kwe-ejenti yokulungisa equkethe i-formaldehyde, imvula yamahhala ye-formaldehyde.
Okwesine, ukulinganisa i-hygroscopicity: ukulenga ithawula, isandla sicwiliswe emanzini ithawula, amanzi awaqedi, okubonisa ukumuncwa okusheshayo nokusabalalisa, i-hygroscopicity enhle;Uma kukhona amaconsi amanzi, kuphakanyiswa ukuthi ithawula ku-softener overdose noma ukulungiswa akwanele.
