A stainless steel kitchen sink is one of the most durable and hygienic choices for any modern kitchen. It resists rust, heat, and stains — but like any metal surface, it can lose its luster if not properly maintained. Regular cleaning prevents dullness, discoloration, and water marks while keeping your sink looking brand-new.
As a professional manufacturer of premium sinks, Shunhan Kitchen & Bath Technology Co., Ltd. shares expert cleaning methods and maintenance tips to help you restore and preserve your stainless steel sink’s natural brilliance.
Daily use exposes your sink to grease, acidic food residues, and mineral deposits from water. Over time, these contaminants can dull the finish or cause surface discoloration. Regular cleaning offers several benefits:
Prevents limescale and hard-water stains
Maintains the sink’s shine and smooth texture
Reduces bacteria and odor buildup
Extends the lifespan of the protective chromium oxide layer
Even though SUS304 stainless steel (used in all Shunhan sinks) naturally resists corrosion, proper care ensures it continues performing at its best for many years.
Before cleaning, prepare the right supplies to avoid scratching or damaging the surface.
| Material | Purpose |
|---|---|
| Soft microfiber cloth | Wiping and polishing |
| Mild dish soap | Removes oil and food residue |
| Baking soda | Gentle abrasive for stains |
| White vinegar | Dissolves mineral deposits |
| Non-abrasive sponge | Scrubbing without scratching |
| Warm water | Rinsing and washing |
| Olive oil or stainless steel polish | Restores shine |
Avoid using steel wool, scouring pads, or harsh chemicals — they can scratch the brushed finish or damage the surface protection.
Start by rinsing the sink with warm water to remove crumbs and food particles. Use a sponge and mild dish soap to wash away grease. This prepares the surface for deep cleaning.
For stuck-on grime or water spots, sprinkle baking soda across the damp surface. Gently scrub along the grain of the steel using a soft sponge. The grain direction is important — scrubbing against it can leave visible marks.
If you see white or cloudy spots from hard water, spray white vinegar onto the sink and let it sit for 5–10 minutes. The mild acidity dissolves calcium and lime buildup. Rinse thoroughly after treatment.
Rinse the entire basin with clean water. Then use a microfiber towel to dry it completely. This prevents new water stains from forming and keeps the surface smooth.
Apply a few drops of olive oil or a stainless steel polish to a soft cloth. Rub gently along the grain until the surface glows. Polishing not only restores the sink’s reflective finish but also forms a thin barrier against fingerprints and soap residue.
For more stubborn dirt or discoloration, perform a deeper cleaning once a week:
Create a Paste: Mix three parts baking soda with one part water.
Apply Evenly: Spread across discolored or scratched areas.
Let Sit for 5–10 Minutes: Allow gentle chemical action.
Scrub Along the Grain: Use a non-abrasive pad to lift grime.
Rinse and Dry Completely: Prevent moisture buildup afterward.
For the drain area or edges, use an old soft-bristled toothbrush with dish soap to reach tight corners.
Even high-quality stainless steel can lose its appearance if cleaned incorrectly. Avoid these common errors:
Using Steel Wool or Wire Brushes: They cause scratches and permanent swirl marks.
Leaving Water Standing: Hard water minerals can etch or dull the surface.
Using Chlorine or Bleach: These harsh chemicals can corrode stainless steel over time.
Cleaning Against the Grain: Always follow the brushed direction for a uniform finish.
Ignoring Daily Drying: Wiping dry after use prevents water spots and keeps the surface glossy.
