2. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   Polishing stainless steel can also increase its sanitary benefits. The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer.

3. Surface finishing - Wikipedia

   en.wikipedia.org/wiki/Surface_finishing

   One takes great care to remove any surface defects in the metal, like pits, that could allow bacteria to grow. A #4 dairy or sanitary finish is produced by polishing with a 180–240 grit belt or wheel finish softened with 120–240 grit greaseless compound or a fine non woven abrasive belt or pad. #6 Finish. Also known as a fine satin finish.

4. Scouring pad - Wikipedia

   en.wikipedia.org/wiki/Scouring_pad

   Cleaning with a scouring pad. Toroidal scouring pad made of plastic wires, thus less aggressive to non-stick surfaces. A scouring pad or scourer is a small pad of metal or plastic mesh used for scouring a surface. Some scouring pads have one side made of a soft sponge-like material and the other is the aforementioned mesh.

5. Electropolishing - Wikipedia

   en.wikipedia.org/wiki/Electropolishing

   Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.

6. Chemical-mechanical polishing - Wikipedia

   en.wikipedia.org/wiki/Chemical-mechanical_polishing

   The process uses an abrasive and corrosive chemical slurry (commonly a colloid) in conjunction with a polishing pad and retaining ring, typically of a greater diameter than the wafer. The pad and wafer are pressed together by a dynamic polishing head and held in place by a plastic retaining ring.

7. Scotch-Brite - Wikipedia

   en.wikipedia.org/wiki/Scotch-Brite

   Scotch-brite. Scotch-Brite is a line of abrasive products produced by 3M.The product line includes scouring pads and tools for home uses such as dish washing and scrubbing, as well as various types of surfaces for industrial applications, such as discs, belts, and rotating brushes, with varying compositions and levels of hardness.

8. Lapping - Wikipedia

   en.wikipedia.org/wiki/Lapping

   Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.

9. Quench polish quench - Wikipedia

   en.wikipedia.org/wiki/Quench_polish_quench

   Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1]
