Qhov zoo-polished yuav tsum tau degreased. Qhov tseeb yog tias tsis muaj oxide zaj duab xis tuaj yeem tshwm sim tsuas yog ntawm qhov chaw huv huv. Yog li, tsis muaj qhov xwm txheej twg tus txheej txheem no yuav tsum tsis saib xyuas. Degrease cov hlau ntawm txoj kev sib txawv. Qhov kev xaiv yooj yim tshaj plaws yog so cov hlau nrog acetone, roj av lossis lub siab dawb. Tab sis nws zoo dua los siv cov qauv hauv qab no. Yaug ib feem hauv cov dej sov xab npum. Tom qab ntawd raus hauv cov tshuaj uas tsis muaj zog ntawm caustic sis dej qab zib. Nws yuav tsum raug sau tseg tias qhov nce ntawm qhov kub ntawm cov tshuaj muaj qhov cuam tshuam zoo ntawm kev ua kom huv hlau. Qhov ntsuas kub zoo tshaj yog 100 degrees Celsius. Nws raug nquahu kom nqus cov ntu hauv cov tshuaj rau 30 feeb. Lub sijhawm no zoo heev. Txhawm rau kom ua tiav cov txheej txheem degreasing, yaug cov hlau hauv dej los yog hliv nrog dej npau npau.
