To remove scratch from stainless steel sink surfaces, first check the brushed grain direction. Most stainless steel sinks have a visible linear finish, and cleaning against the grain may make scratches more obvious. For light marks, use a mild stainless steel cleaner or fine non-scratch pad, wipe along the grain, rinse fully, then dry with a soft cloth.
Stainless steel is widely used in kitchens because it contains at least 10.5% chromium, which forms a protective surface layer. For better corrosion resistance, SUS304 stainless steel commonly contains about 18% chromium and 8% nickel.
| Scratch Type | Suggested Treatment |
|---|---|
| Light hairline mark | Soft cloth and stainless cleaner |
| Brush direction mark | Wipe along the grain |
| Deeper scratch | Fine polishing test first |
| Repeated surface marks | Use sink grid protection |
Scratch complaints are closely related to surface finishing and packaging. A trader usually supplies finished models, while a stainless steel sink manufacturer can control material grade, sheet thickness, forming, welding, polishing, cleaning, accessories, and carton protection.
Our team supports OEM / ODM process planning for sink size, bowl depth, mounting type, surface finish, drain position, sound pad, coating, logo, carton design, and export documents. This helps improve consistency for bulk supply considerations and project orders.
The manufacturing process overview includes stainless steel sheet cutting, bowl stretching or handmade forming, welding, grinding, polishing, surface cleaning, drain fitting inspection, sound pad application, packing, and final inspection.
Quality control checkpoints include material verification, thickness check, bowl size accuracy, welding strength, surface scratch inspection, edge smoothness, drain hole accuracy, leakage test, carton strength, and label accuracy.
Material standards used should be confirmed before production, especially for kitchen projects requiring long-term appearance stability. For export market compliance, buyers should check steel grade, gauge, surface finish, accessory standard, installation manual, carton marks, packaging protection, and destination market requirements.
A practical project sourcing checklist should include sink type, finish sample, thickness, bowl size, drain position, MOQ, lead time, packaging method, sample approval, and after-sales support.
Correct scratch removal improves surface appearance, while controlled manufacturing and careful packaging reduce visible damage before shipment.
