To repair stainless steel sink scratches, first check the scratch depth and brushed grain direction. Light hairline scratches can often be improved by using a mild stainless steel cleaner, a soft cloth, and gentle wiping along the grain. Deep scratches may need professional polishing, especially for showroom, hotel, or apartment project sinks.
Stainless steel contains at least 10.5% chromium, which helps form a protective surface layer. SUS304 stainless steel commonly contains about 18% chromium and 8% nickel, giving stronger corrosion resistance for kitchen use.
| Scratch Type | Repair Method |
|---|---|
| Light hairline scratch | Wipe along the grain |
| Cleaning mark | Use mild cleaner |
| Deeper visible scratch | Test fine polishing first |
| Repeated scratch risk | Add sink grid protection |
A trader usually supplies finished sinks, while a stainless steel sink manufacturer can control material grade, thickness, forming, welding, polishing, cleaning, accessories, and packaging.
Our team supports OEM / ODM process development for sink size, bowl depth, mounting type, surface finish, drain position, sound pad, coating, logo, carton design, and export documents. This helps reduce scratch complaints during bulk supply.
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 projects requiring consistent surface appearance. For export market compliance, buyers should check steel grade, gauge, finish sample, accessory standard, installation manual, carton marks, packaging protection, and destination market requirements.
A practical project sourcing checklist should include sink type, surface finish, thickness, bowl size, drain position, MOQ, lead time, sample approval, packaging method, and after-sales support.
Correct scratch repair can improve appearance, but controlled polishing, careful inspection, and strong packaging help reduce visible defects before shipment.
