Manje, kunezindlela eziningi ezahlukene zokuhlanza izitsha zengilazi elabhorethri, ukuwasha ngezandla, ukuwasha nge-ultrasonic, umshini wokuwasha ozenzakalelayo, kanye nomshini wokuwasha wengilazi ozenzakalelayo. Kodwa-ke, ukuhlanzeka kokuhlanza kunquma njalo ukunemba kokuhlolwa okulandelayo noma ngisho nempumelelo yokuhlolwa. Umhleli ufingqa izici eziningana ezinkulu ezithinta ukuhlanza, futhi uzifingqa ngamaphuzu amahlanu e-CTWMT:

C: Ikhemistri
Ngokuya ngenhloso yezinto zokuhlanza, khetha izingxenye ezahlukene zensipho

T: Izinga lokushisa 
Ngokuvamile, izinga lokushisa eliphezulu lokuwasha lizoba nomphumela ongcono wokuwasha

W: Ikhwalithi Yamanzi
Amanzi ayindlela eyinhloko yokuhlanza, kodwa ikhwalithi yamanzi iyahlukahluka kuye ngendawo, ngakho-ke umphumela wokuhlanza awunakuqinisekiswa kahle.

M: Amandla omshini
Izinsalela zisuswa ebusweni bomkhumbi ngamandla angaphandle

Isikhathi
Zonke ezinye izinto zilingana, ngokuvamile, isikhathi eside sokuhlanza, zizoba nomphumela omuhle wokuhlanza.

Umgomo wokuwasha izingilazi okuzenzakalelayo: ukufudumeza amanzi, kufakwe insipho ekhethekile ngepompo yokujikeleza iye epayipini lamabhasikidi ochwepheshe ngokucindezela okuphansi kanye nokujikeleza okuphezulu ukuze kugezwe ubuso bezingilazi zangaphakathi, Izingalo zokufutha ezingenhla nezingezansi zihlanza ubuso bangaphandle bezingilazi. Ngesikhathi sokuhlanza ngokwesayensi kanye nezinyathelo, ukuze kufezwe injongo yokuhlanza izingilazi.
