MP (Mechanical polishing): ngokuqhelekileyo isetyenziselwa umaleko we-oxidation, imingxuma, kunye nemikrwelo kumphezulu wemibhobho yentsimbi. Ukukhanya kwayo kunye nesiphumo kuxhomekeke kuhlobo lwendlela yokucubungula. Ukongeza, ukupolisha ngoomatshini, nangona kukuhle, kunokunciphisa ukumelana nokubola. Ngoko ke, xa isetyenziswe kwiindawo ezinobungozi, unyango lwe-passivation luyafuneka. Ngaphezu koko, kudla ngokubakho iintsalela zezinto zokupholisha kumphezulu wemibhobho yentsimbi.
