Water spots are one of the most common frustrations for stainless steel sink owners. These dull, cloudy marks are caused by minerals in hard water that dry and leave calcium and magnesium deposits behind. Fortunately, with the right habits and cleaning methods, you can keep your stainless steel sink spotless and shining like new.
Water spots are mineral stains left behind after water evaporates. Hard water, common in many homes, contains high levels of dissolved minerals that settle on the surface. Over time, these residues can:
Dull the sink’s polished or brushed finish.
Trap more grime and discoloration.
Cause corrosion if not cleaned regularly.
Even high-grade stainless steel like Shunhan’s 304 material can show water spots if moisture remains on the surface for long periods.
The simplest and most effective way to prevent water spots is to never let water dry naturally on the sink.
Routine:
After each use, rinse the sink with warm water.
Wipe it completely dry using a soft microfiber cloth or towel.
Follow the direction of the grain for best results.
Why it works:
Removing water before it evaporates eliminates mineral residue entirely.
This single habit can reduce 90% of water-spot buildup.
A vinegar rinse dissolves existing mineral deposits and prevents new ones from forming.
How to do it:
Mix equal parts white vinegar and water in a spray bottle.
Spray evenly across the sink surface.
Let sit for 3–5 minutes.
Wipe with a soft sponge and rinse thoroughly.
Dry with a clean towel.
Vinegar is mild yet powerful — safe for stainless steel and perfect for maintaining Shunhan sinks’ mirror or brushed finishes.
Creating a light barrier on the sink surface repels water and slows down spot formation.
Olive oil or baby oil: Apply a few drops to a soft cloth and buff lightly along the grain.
Stainless steel cleaner or polish: Use a brand-safe formula designed for kitchen use.
Carnauba wax or mineral oil: Adds a longer-lasting hydrophobic layer.
Steps:
Apply oil or polish sparingly.
Buff gently with a microfiber towel until the surface shines.
Repeat once a week for lasting results.
This method not only prevents water spots but also enhances the sink’s reflective finish.
A sink grid elevates dishes and keeps water from pooling in one place.
Benefits:
Prevents scratching from cookware.
Improves air circulation for faster drying.
Reduces standing water that leads to mineral deposits.
Shunhan’s sink accessories often include precision-fit grids that protect the basin while maintaining easy drainage.
If your home has hard water, consider installing a water softener or under-sink filtration system.
Advantages:
Significantly fewer mineral deposits.
Better water flow and drainage.
Reduced spotting on sinks, faucets, and dishware.
Long-term, softened water preserves the luster and lifespan of your stainless steel sink.
Use mild dish soap, vinegar, or baking soda.
Rinse and dry the sink daily.
Polish weekly with a microfiber cloth.
Leave wet sponges, dishcloths, or metal pots in the sink.
Use steel wool or harsh abrasives — they scratch and trap minerals.
Use chlorine bleach or ammonia — they can discolor stainless steel.
A few small adjustments can make a big difference in preventing permanent water stains or dullness.
Sprinkle baking soda around the sink.
Spray vinegar to create fizz.
Scrub gently with a soft sponge.
Rinse thoroughly.
Dry and apply a light polish.
This routine keeps your sink clean, smooth, and water-repellent.
