Chikonzero chekuonekwa kwemafaro ekupfeka kunogona kushanda chero chinhu chesimbi: rivet, pini inokanganwa, nut, nail. Rust tsvina haisi nguva dzose yakashambidzwa panguva yekugeza. Tinopa nzira dzokuti tibvise nyore nyore dziya uye kubvisa tsvina pamapfeko:
- Kuchenesa kubva mudziku kunoitwa nemon uye hydrogen peroxide. Zvipukanana zvinofanira kunge zvakanyoroveswa nejisi remuori uye zvinopisa zvisikwa zvakasvibiswa. Kubva pane tsvina kubva mumononi zvinogona kubviswa nenzira ye peroxide. Mushure meizvi, chinhu chinofanira kushambidzwa mumvura;
- Zvichengetedzwa kubva kumarara pamapendero zvinogona kubviswa nekubatsirwa kweAactic acid. Iyo asidi inofanira kusanganiswa nemvura (1 kapu yemvura 2 maspuniji evhiniga), inopisa uye kuisa ipapo chinhu chine tsvina kwemaminitsi mashanu. Zvadaro simesa chigadzirwa mumvura inotonhora.
