Short answer: Metal degreasing removes oils, shop soil and residues before coating, plating or bonding so the finish actually adheres; alkaline soak and aqueous spray handle most production, solvent or vapour cleans precision parts, and pickling strips scale — the right method depends on the soil, the substrate and the next process.
At a Glance
Why Clean Before Finishing
Any oil or soil blocks conversion coating, anodise or paint, causing blisters and peeling — so degreasing is step one of every Metal Surface Treatment Guide 그리고 Anodized Aluminum Guide line, and of How To Prevent Metal Rust. Clean surfaces also read true on Stainless Steel Surface Finishes.
Choosing the Method
Alkaline soak and spray suit general oils on steel and galvanised from Galvanized Steel Supplier; aqueous spray scales to volume with a rinse and dry; vapour/solvent gives fast, residue-free precision cleaning (now VOC-regulated); ultrasonic cavitation reaches intricate castings from Casting Supplier; acid pickling removes both scale and oil before passivation per Passivation Vs Pickling.
Quality, Rinse & Handling
Verify by water-break test (a clean surface wets evenly, no beading), rinse fully and dry to avoid flash rust, then coat promptly. Corrosion inhibitors from Metal Corrosion Inhibitor Guide protect the cleaned part in storage, and we certificate process per Mill Test Certificate Guide.

자주 묻는 질문
Oil and soil block conversion coating, anodising and paint, causing blisters and poor adhesion — cleaning is the first step of any finish.
Solvent/vapour degreasing cleans fast and residue-free for precision parts but is VOC-regulated; aqueous alkaline spray is cheaper, safer and scales to volume with a rinse.
Ultrasonic cavitation reaches intricate, blind or porous features that soak or spray miss — common for castings and small precision parts.
A water-break test: a properly cleaned surface wets evenly with no beading; then rinse, dry and coat promptly to avoid flash rust.
