ʻO kahi kākālo kūlohelohe pilikino kahi mahele loea, kahi mea e koi nui ai. ʻO ka mea maʻamau, nā bolts, nā waki, nā rivets, etc., i mea e hōʻoiaʻiʻo ai i ka palekana a i ʻole i ʻole ka mea maʻamau ʻaʻole pono e noʻonoʻo i ka hopena o ke ʻano, ka maikaʻi o nā wahi a i ʻole nā ​​kūlana hana ʻē aʻe. ʻO nā kumuhana maʻamau ka carbon steel, haʻahaʻa haʻahaʻa haʻahaʻa a me nā metala non-ferrous. Akā i kahi mau hanana kūikawā, pono nā lako wikiwiki e hoʻokō i nā kūlana o ka ʻoi loa o ka corrosion a i ʻole ka ikaika kiʻekiʻe, he nui nā kila kila a me nā ikaika kiʻekiʻe stainless steel. ʻO nā pilikia ʻeono e pono ai e mālama pono i ka hoʻohana ʻana a me ka mālama ʻana i nā kaula wili hoʻopili.
1. Ka wikiwiki ʻo ke kaʻina o ka rinsing o ka ua wili o ka pahu a ʻoi ka mea pono loa. I ka wā o ke kaʻina hana, loaʻa ke koena ma luna o ka ili o ka ua wili o ka pahu. ʻO kēia ʻāpana ka holoi ʻana ma hope o ka holoi ʻana o ka mea hoʻomaʻemaʻe silicate.
2. I ka wā hoʻowalewale, pono e hoʻohui ʻia ka hoʻokau, inā ʻaʻole e ʻalo ʻia ka oxidation i loko o ke aila a pau.
3. E ʻike ʻia ke koena o ka phosphide keʻokeʻo ma ka papakū o nā pihi kiʻekiʻe, e hōʻike ana i ka (point 1) i ka nānā ʻole ʻia ʻana o ka nānā ʻana i ka wā o ka hana. 4. ʻO ke ʻano hōʻino i ka ʻili o nā ʻāpana i mea e hoʻoneʻe ai i ka noi ke kūlohelohe i hōʻike ʻia, ʻaʻole e hōʻike pono ka mālama ʻana i ke ʻano wela a ʻaʻole i pau loa ke koena o ka alkaline ma luna o ka ʻili.
5. E holoi nā ʻāpana ʻāpana i ka holoi ʻana, a pono e loli pinepine ka wai i hoʻohana ʻia no ka rinsing.
6. Hōʻike ka hopena o ke kaʻo ʻana no ka lōʻihi o ka hoʻohana ʻana i ka aila huakaʻi, a pono e hoʻohui ʻia a i ʻole a paʻa.
