Stainless steel sinks are valued for their strength, hygiene, and timeless appearance. Yet, with daily use, even premium sinks can develop scratches from utensils, pots, and cleaning tools. While these marks are common, they don’t have to be permanent.
As Shunhan Kitchen & Bath Technology Co., Ltd., a professional manufacturer of high-quality stainless steel sinks, we provide expert guidance on how to safely and effectively remove scratches — restoring your sink’s original smooth and polished surface.
Stainless steel is an alloy containing iron, chromium, and nickel, which forms a thin protective film on the surface that resists corrosion. However, the same smooth finish that gives it beauty also makes it prone to visible marks.
Light scratches often appear as fine lines from normal cleaning or dish contact.
Deep scratches may occur from sharp utensils or abrasive pads.
The good news is that most scratches can be minimized or removed with the right technique — and your sink can look nearly new again.
Gather the proper tools before you start. Avoid anything too harsh that could worsen the scratches.
| Material | Purpose |
|---|---|
| Non-abrasive scrubbing pad | For gentle polishing |
| Fine-grit sandpaper (400–800 grit) | For deeper scratches |
| Baking soda | Mild abrasive cleaner |
| Soft microfiber cloth | Wiping and buffing |
| Stainless steel cleaner or olive oil | Restoring shine |
| Warm water | Cleaning residue |
Always work along the grain direction of your sink’s finish. This ensures an even, factory-like appearance after polishing.
Light scratches are the most common and easiest to remove. Follow these simple steps:
Wash with warm water and mild dish soap to remove grease and debris. Dry completely to clearly see the scratches.
Make a paste using baking soda and water (3:1 ratio). Spread it evenly over the scratched area.
Using a soft sponge or non-abrasive pad, gently rub in the direction of the grain. Continue for 2–3 minutes with light pressure.
Rinse the surface with clean water, then dry thoroughly with a microfiber cloth. You’ll notice light scratches fading.
Apply stainless steel cleaner or a few drops of olive oil on a clean cloth. Buff along the grain to restore the reflective finish.
This method works well for brushed or satin finishes found on most Shunhan SUS304 sinks.
Deeper scratches may require additional care. If the mark catches your fingernail, follow these steps:
Select 400- to 800-grit wet/dry sandpaper. Wet the surface slightly and gently sand along the grain. Never sand across it.
Work lightly and evenly around the scratch to blend it into the surrounding surface. Avoid over-sanding one spot.
Move to a higher grit (1000–1500) for a smoother finish. This step restores the natural brushing pattern.
Rinse the sink, dry completely, and apply a stainless steel polish or metal restoration compound. Buff with a microfiber towel until uniform.
If the sink has a mirror finish, consider using a dedicated stainless steel polishing kit for professional-level results.
Once your sink looks new again, simple habits can help prevent future damage.
Use a Sink Grid: Protects the base from heavy pots or sharp objects.
Avoid Steel Wool: Always clean with soft sponges or microfiber cloths.
Rinse After Use: Food particles and saltwater can increase surface wear.
Wipe Dry Daily: Prevents mineral buildup that can highlight scratches.
Polish Regularly: Monthly maintenance preserves shine and smoothness.
Every Shunhan stainless steel sink is engineered with a high-quality brushed finish that naturally hides minor scratches, but regular care keeps it looking flawless.
If scratches are severe or cover a large area, you may want to use a commercial stainless steel restoration kit. These kits typically include:
Multi-grit polishing pads
Restoration compound or cream
Clear instructions for grain alignment
For commercial kitchens or older sinks, professional re-brushing or refinishing can completely rejuvenate the surface. Shunhan sinks, made with precision CNC forming and premium SUS304 material, are designed for easy professional restoration without warping or discoloration.
