Ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe ʻia, ʻoi aku ka lōʻihi o ka wōnati shell grit, angular a me nā ʻano he nui, akā ua manaʻo ʻia he 'abrasive palupalu'. He pani maikaʻi loa ia no ke one (silica manuahi) no ka pale ʻana i nā pilikia olakino inhalation.
ʻOi aku ka maikaʻi o ka hoʻomaʻemaʻe ʻana me ka puhi ʻana i ka iwi wōnati i kahi e hoʻololi ʻole ʻia ai ka ʻili o ka substrate ma lalo o kona kapa pena, lepo, momona, unahi, kalapona, etc. Hiki ke hoʻohana ʻia ka ʻeleʻele ʻeleʻele ma ke ʻano he hui palupalu i ka wehe ʻana i nā mea ʻē a i ʻole ka uhi ʻana mai ka ʻili me ka ʻole o ke kālai ʻana, ka ʻohi ʻana a i ʻole ka hoʻomaʻemaʻe ʻana i nā wahi i hoʻomaʻemaʻe ʻia.
Ke hoʻohana ʻia me nā mea hoʻoheheʻe ʻana o ka iwi wōnati pono, ʻo nā noi hoʻomaʻemaʻe maʻamau ka wehe ʻana i nā panela kaʻa a me nā kaʻa, ka hoʻomaʻemaʻe ʻana i nā ʻōpala palupalu, nā mea hoʻonani nani, nā mea lima a me nā kaʻa uila ma mua o ka hoʻihoʻi ʻana, ka hoʻoheheʻe ʻana i nā plastic a me ka nānā ʻana. Ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe hoʻomaʻemaʻe, hoʻoneʻe ka wōnati shell grit i ka pena, flash, burrs a me nā hemahema ʻē aʻe i loko o ka plastic a me ka hoʻoheheʻe ʻana i ka pahu, ka alumini a me ka zinc die-casting a me nā ʻoihana uila.
