Kuzvirovera wega kuchinjisa chikamu chemishini chikamu, chiri mukuda kukuru. Kazhinji, mabhanditi, zviyero, rivets, nezvimwewo, kuitira kuti uve nechokwadi chekuchengeteka kana kazhinji haufanire kufunga nezve pesvedzero yekudziya, nharaunda yakaipa kana mamwe mamiriro ezvinhu ane ngozi ekushanda. Zvinhu zvakajairika kabhoni simbi, yakadzika alloy iron uye isina-feri simbi. Asi mune zviitiko zvakanyanya, zvigadzirwa zvekumhanyisa zvinoda kusangana nemamiriro ezvinhu ekorori yakasimba kana yakasimba simba, kune akawanda asina kusimba simbi uye Ultra yakakwirira simba isimbi isina simba yakabuda. Matambudziko matanhatu anotevera anofanira kutariswa kana uchinge uchishandisa nekuchengetedza waya yemuswe.
1. Maitiro ekuwasha waya yekudonha waya anokurumidza uye anoda kuve anongwarira. Munguva yekuita iyi, pachave nezvinosara pamusoro pevhu rekudonha muswe waya. Iyi nhanho yekugeza mushure mekushambidzwa kwesilatoni.
2. Munguva yekuedza, dhaka rinofanira kusangana, zvikasadaro oxidation shoma ichaitika muiri yekudzima mafuta.
3. White chena phosphide zvasara achaonekwa pamusoro-yakasimba-simba maseko, zvichiratidza (pepa 1) kuti kuongorora hakuna kuchenjera zvakakwana panguva yekushanda. 4. Icho kusviba chiitiko chiri pamusoro pezvikamu chinogadzira chemakemikari reverse application, zvichiratidza kuti kurapwa kwekupisa hakuitwe zvakakwana uye alkaline inosara pamusoro haina kubviswa zvachose.
5. Nzvimbo dzakasarudzika dzinoita ngura mu rinsing, uye mvura inoshandiswa rinsing inofanira kuchinjwa kazhinji.
6. Kunyanya kuwanda kunoratidza kuti mafuta ekuzora ave achishandiswa kwenguva yakareba, uye inoda kuwedzerwa kana kutsiviwa.
