Vuam hlau cia yuav tsum tau nruj ib puag ncig tswj: kub (10-30 degree), av noo (tsawg dua los yog sib luag rau 60% rh), thiab qhov cua. Zam kev kub siab uas ua kom nrawm dua txheej lossis qis kub uas ua rau brittle bacture. Kev tiv thaiv noo noo yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov hlau thiab stainless hlau vuam hlau thaum yav qab teb lub caij nyob rau sab qab teb Suav, piv txwv li cov txee kom qhuav (piv txwv li tsawg kawg 20 cm saum toj no hauv av). Kev ntim khoom ncaj ncees ncaj qha cuam tshuam oxidation kev tiv thaiv; Tom qab qhib, khaws cia rau hauv hnab ntim khoom.
Cov khoom sib txawv muaj cov kev txwv tshwj xeeb: cov pa roj carbon vuam hlau tau pom zoo kom siv nrog tus desiccant; Cov hlau stainless vuam yuav tsum tau kaw tseg ntawm cov roj carbon hlau los tiv thaiv cov corrosion electrochemical; Aluminium alloy vuam hlau yuav tsum muaj kev tiv thaiv los ntawm cov tshuaj pleev xim oxide ntau dhau; Cov kev thaiv cov roj hauv cov roj ntsha tau pom zoo thaum lub sijhawm khaws cia. Kev tshuaj xyuas tsis tu ncua (tsawg kawg ib zaug ib hlis twg ib zaug) yuav tsum tau ua los tshawb xyuas cov tshuaj pleev ib ce xws li xeb tsis xeb thiab deformation. Cov xeb me me tuaj yeem tshem tawm nrog cov xuab zeb (cov sanding tob tsawg dua lossis sib npaug rau 0.1 hli).
