1. I loko o ka lumi maʻemaʻe, pono e hoʻonohonoho ʻia nā ʻano lumi mālama a me ka hāʻawi kemika like ʻole ma muli o nā koi hana hana huahana a me nā waiwai kino a me kemika o ka kemika. Pono e hoʻohana ʻia nā paipu e hoʻolako i nā kemika e pono ai i nā lako hana. ʻO nā lumi mālama a me ka hāʻawi kemika i loko o ka lumi maʻemaʻe e waiho pinepine ʻia ma kahi hana kōkua, ma ka papahele o kahi hale hoʻokahi papahele a i ʻole he nui papahele, kokoke i kahi paia waho. Pono e mālama ʻokoʻa ʻia nā kemika e like me ko lākou mau waiwai kino a me kemika. Pono e waiho ʻia nā kemika kūpono ʻole i loko o nā lumi mālama a me ka hāʻawi kemika kaʻawale, i hoʻokaʻawale ʻia e nā ʻāpana paʻa. Pono e mālama ʻia nā kemika weliweli i loko o nā lumi mālama a hāʻawi paha me ka helu pale ahi o ka liʻiliʻi he 2.0 mau hola ma waena o nā lumi e pili ana. Pono e waiho ʻia kēia mau lumi i loko o kahi lumi ma ka papahele mua o ka hale hana, kokoke i kahi paia waho.
2. Loaʻa pinepine i nā lumi maʻemaʻe i nā ʻoihana uila nā lumi mālama a me nā lumi hoʻolaha no nā waikawa a me nā alkalis, a me nā mea hoʻoheheʻe lapalapa. ʻO nā lumi mālama a me nā lumi hoʻolaha waikawa ka mea maʻamau e mālama i nā ʻōnaehana mālama a me nā ʻōnaehana hoʻolaha no ka waikawa sulfuric, ka waikawa phosphoric, ka waikawa hydrofluoric, a me ka waikawa hydrochloric. ʻO nā lumi mālama a me nā lumi hoʻolaha alkali ka mea maʻamau e mālama i nā ʻōnaehana mālama a me nā ʻōnaehana hoʻolaha no ka sodium hydroxide, ka hydroxide cake, ka ammonium hydroxide, a me ka tetramethylammonium hydroxide. ʻO nā lumi mālama a me nā lumi hoʻolaha mea hoʻoheheʻe lapalapa ka mea maʻamau e mālama i nā ʻōnaehana mālama a me nā ʻōnaehana hoʻolaha no nā mea hoʻoheheʻe organik e like me ka isopropyl alcohol (IPA). Loaʻa i nā lumi maʻemaʻe i nā hale hana hana wafer kaapuni hoʻohui ʻia nā lumi mālama a me nā lumi hoʻolaha slurry polishing. Aia nā lumi mālama a me nā lumi hoʻolaha kemika ma nā wahi hana kōkua a i ʻole nā wahi kākoʻo kokoke a i ʻole e pili ana i nā wahi hana maʻemaʻe, ma ka papahele mua me ke komo pololei ʻana i waho.
3. Ua lako nā lumi mālama a me nā lumi hoʻolaha kemika me nā pahu mālama a i ʻole nā pahu o nā mana like ʻole e pili ana i ke ʻano, ka nui, a me nā ʻano hoʻohana o nā kemika e pono ai no ka hana huahana. Wahi a nā kūlana a me nā lula, pono e mālama ʻokoʻa a hoʻokaʻawale ʻia nā kemika. Pono ka nui o nā pahu a i ʻole nā pahu i hoʻohana ʻia no ka hoʻopau ʻana i nā kemika i ʻehiku lā. Pono hoʻi e hoʻolako ʻia nā pahu a i ʻole nā pahu i kēlā me kēia lā, me ka nui e lawa ai e uhi i ka hoʻopau ʻana i nā kemika i 24 mau hola e pono ai no ka hana huahana. Pono e hoʻokaʻawale ʻia nā lumi mālama a me ka hoʻolaha no nā mea hoʻoheheʻe lapalapa a me nā kemika oxidizing mai nā lumi e pili ana e nā paia paʻa e pale aku i ke ahi me ka helu pale ahi o 3.0 mau hola. Inā aia ma ka papahele mua o kahi hale he nui nā papa, pono e hoʻokaʻawale ʻia lākou mai nā wahi ʻē aʻe e nā papahele ʻaʻole e hiki ke puhi me ka helu pale ahi o 1.5 mau hola. Pono e waiho ʻia ka lumi hoʻomalu kikowaena no ka ʻōnaehana palekana a me ka nānā ʻana o ka kemika i loko o ka lumi maʻemaʻe i loko o kahi lumi ʻokoʻa.
4. Pono e hoʻoholo ʻia ke kiʻekiʻe o nā lumi mālama a me ka hāʻawi ʻana i nā kemika i loko o ka lumi maʻemaʻe ma muli o nā koi o nā lako a me nā paipu a ʻaʻole pono e emi ma lalo o 4.5 mika. Inā aia i loko o ka wahi hana kōkua o ka lumi maʻemaʻe, pono ke kiʻekiʻe o ka lumi mālama a me ka hāʻawi ʻana i nā kemika e kūlike me ke kiʻekiʻe o ka hale.
