Scratches on a stainless steel sink should be handled according to depth, surface finish, and grain direction. Light marks often come from cookware, knives, metal trays, hard cleaning pads, or small particles left on the sink surface. Deep scratches may appear after rough installation or improper handling during transport. Before repair, clean the sink with warm water and neutral detergent, then dry it fully so the scratch condition can be checked clearly.
304 stainless steel is widely used for kitchen sinks because it belongs to the 18-8 stainless steel group, with about 18% chromium and 8% nickel, according to common stainless steel material standards. Chromium helps form a protective surface layer, while nickel supports corrosion resistance and forming stability. Scratch removal should improve the appearance without damaging the brushed stainless steel finish.
For a brushed stainless steel sink, always work along the original grain direction. Apply a small amount of stainless steel polishing cream to a soft cloth or fine polishing pad, then rub gently in straight lines. Do not use circular movement, because swirl marks can become more visible under kitchen lighting. After polishing, rinse the sink thoroughly and wipe it dry with a clean microfiber cloth.
Avoid steel wool, coarse sandpaper, chlorine cleaner, and strong acid cleaner. Stainless steel care guidance from material maintenance references recommends mild cleaning, full rinsing, and drying after washing to reduce water spots, surface stains, and long-term maintenance problems.
| Scratch Condition | Suggested Method | Handling Advice |
|---|---|---|
| Light hairline scratches | Soft cloth with polishing cream | Suitable for daily surface care |
| Visible brushed marks | Fine stainless steel polishing pad | Work slowly along the grain |
| Water stains with light marks | Mild cleaner before polishing | Remove residue before repair |
| Deep scratches | Professional refinishing review | Avoid aggressive sanding |
Scratch removal is easier when the sink surface is well finished from the beginning. As a stainless steel sink manufacturer, SHUNHAN focuses on material selection, handmade sink forming, welding, grinding, polishing, edge finishing, cleaning, and final inspection. A stable brushed surface needs even polishing direction, smooth corners, neat weld treatment, and protective packaging before shipment.
