ʻO nā ala hoʻoneʻe ʻōpala e hoʻomaikaʻi i ka hana anti-rust o ka non-ferrouskalai metalaʻo nā ʻāpana penei:
(1) Hoʻokomo i ka ʻaila oke kalaiwa anaʻāpana i loko o ka hui ʻana ma hope o ka mālama ʻana;
(2) Hana mua ʻana oke kalaiwa anaʻāpana;
(3) hoʻomākaukau i ka wai lapaʻau;
(4) Hoʻopaʻa i ka mea i hana mua ʻiaʻāpana kalaimālama ʻia me ka lāʻau hoʻohui silane i loko o ka hopena lapaʻau no ka hoʻohana ʻana ma hope;
(5) Hoʻohu i nā ʻāpana forging ʻokoʻa i loko o ka lāʻau lapaʻau i hoʻomākaukau ʻia, a holoi pinepine iā lākou me ka wai deionized ma hope o ka lawe ʻana i waho. Ma hope o ka maloʻo ʻana, e wehe ʻia ka ʻōpala o kaʻāpana kalaihiki ke hoʻopau.
ʻAʻole hiki i kēia ʻano derusting ke wehe koke i nā ʻeleʻele ma luna o ka ʻili o nā ʻāpana forging, akā hoʻomaikaʻi maikaʻi hoʻi i ka hana anti-rust o nā ʻāpana forging metala non-ferrous, i hiki ai i nā ʻāpana forging metala ʻole ke mālama i ka lōʻihi- hana anti-rust ma hope o ka hoʻopau ʻana.
