Prep first
Before you start
- Blot up standing water promptly with a dry, white absorbent cloth or paper towels.
- Pretest any cleaner on a hidden area first.
- Identify the sink's material before you clean, because each finish has its own limits.
- Dry the sink fully when you're done.
Water marks on a sink look like white rings, a thin film or a dull patch, and the right fix depends on what the sink is made of. Enameled cast iron is the one to handle with care, since abrasives should be used sparingly and always with water. Most marks lift with a gentle, non-abrasive wipe, but dull or scratched acrylic usually needs the manufacturer's repair service instead.
Red, pink or green marks come from the tap water itself, so a quick wipe rarely clears them. Keep a scouring cleanser for stubborn spots only, and rinse it off fully so no grit is left behind. On a black sink, rinse well between passes so residue doesn't cloud the finish.

5 steps
Step by step
Step 1 of 5
Blot up the standing water
Start with a dry, white absorbent cloth or paper towels, pressing the water up rather than wiping it across the finish. Work from the edge of any puddle toward the middle so the water doesn't spread into a bigger ring. Switch to a fresh towel once the first one is damp.
Step 2 of 5
Test the cleaner on a hidden spot
Pick a spot that doesn't show, like the inside of the basin or the area under the rim. Put a small amount of the mild cream cleaner on it, rinse with clean tap water, and dry it. If the finish still looks even and matches the rest of the sink, you can move on.
Tip. Look for any change in shine or dullness, not only color.
Step 3 of 5
Apply the mild cleaner gently
Put a small amount of the mild, non-scratching cream cleaner or polish on a soft cloth or sponge. Work it over the water marks in gentle, even strokes, keeping the surface damp with clean water as you go. Stop when the marks lift and check that the finish is still even.
Careful. Never use an abrasive cleaner without water, and keep abrasives off acrylic, cast iron and porcelain.
Step 4 of 5
Rinse off every trace of cleaner
Rinse the whole sink with clean tap water until no cream or film is left in the corners or along the drain. Rinse the faucet and the counter beside it as well, so none of the cleaner dries there.
Careful. Cleaners should never soak on the surface; rinse any overspray off nearby surfaces.
Step 5 of 5
Dry the sink completely
Dry the sink with clean disposable wipes or an air blower, working until no damp spots remain. Drying it right away is what keeps new marks from forming, so don't leave it to air dry.
Tip. Use a fresh wipe once the first one is damp.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on sinks, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
The marks should lift and the surface should look even, with no dull patch or leftover film. If the finish looks dull or scratched after cleaning, stop there, since more scrubbing can make it worse.
What changes for yours
Adjust for your sinks
Porcelain or ceramic sink
Vitreous china and porcelain take the mild cream cleaner well, and water is safe for them too. Rinse after each use and dry with a soft cloth, which keeps most marks from forming. Mild soap and warm water handle light buildup.
Stick with the mild cleaner for the marks themselves, and don't move to a harsher product just because the first pass looks light.
Kitchen sink
Kitchen sinks get the most rinsing and the most spotting, so the routine matters as much as the cleaning. Dry the sink after each big use so marks don't set between cleanings. Check the material first, because kitchen sinks can be stainless steel, enameled cast iron or porcelain.
Each of those finishes has its own limits, and the card for your material applies. Clean the faucet and the rim too, since spotting builds up there.
Bathroom sink
Bathroom sinks can be acrylic or porcelain, and acrylic needs the gentlest handling. Check which one you have before cleaning, since the rules change with the material. Use only the mild cream cleaner and a soft cloth on the basin.
Water marks around the drain and the faucet base respond to the same method. Rinse well and dry so the area doesn't dry in a ring.
Stainless steel sink
Stainless steel shows water marks as dull rings or spots, and the mild cream cleaner handles them. Rinse fully and dry with clean wipes so the rings don't form as the water evaporates.
Work with the grain of the metal rather than in circles, and don't let the cleaner sit on the seams where it can dry. Finish with a dry wipe to bring back the shine.
Enameled cast iron sink
Enameled cast iron is heavy and takes the mild cream cleaner well, as long as the scrubbing stays soft. Rinse and dry promptly, because standing water is what leaves the marks behind.
Keep the work soft, with a cloth or sponge, and let the mild cleaner do the lifting. If a mark is still there after the mild method, it's a set-in problem, and the set-in options are the next step.
Colored water stains
Colored rings are a different problem from white spots, and the color alone doesn't tell you the cause. Start with the mild cream cleaner on a hidden test spot, then use the full method if it looks safe.
Watch whether the color lifts with each pass rather than piling on stronger products. If it doesn't lift, stop before trying anything harsher, since a strong product can strip the finish along with the stain.
Black sink
A black sink uses the same mild method, but the finish under the color decides what it can take. Test any cleaner on a hidden spot first, since the color alone doesn't tell you the material.
Dry the basin fully after each cleaning, because water marks show more clearly on a dark surface. Stay with the soft cloth and mild cream cleaner, since anything harsher can damage the finish.
Heavy or long-standing buildup
Old marks that have been sitting for a while often need a second pass rather than a stronger product. Work the mild cream cleaner in gently, then rinse it off right away. Give the sink a full dry before you judge the result, because a damp patch can look like a mark.
If the mark is dried on and still there, the stronger options are for specific finishes only. On enameled cast iron, abrasive cleaners can be used sparingly and always with water, and a rust remover made for enamel can handle occasional rust when used as its label directs. Rinse any of these off thoroughly afterward.
Stronger steps don't fix a finish that has already worn through. Dull or scratched acrylic needs repair from the manufacturer, not more effort, and a mark that survives every step here is often a finish problem rather than a stain.

What makes it worse
Mistakes to avoid
Don't spray aerosol cleaners on acrylic
Aerosol products throw a fine mist that settles on the surface and on nearby areas. Use the cream cleaner on a cloth instead, because you control how much goes on.
Don't use ammonia on porcelain
Ammonia cleaners can damage the finish of a vitreous china sink, even when they seem to lift the mark. The mild cream cleaner is the method for this surface, so stick with it.
Don't use harsh cleaners on a PVD faucet
PVD faucet finishes don't take ammonia, bleach or acid. Clean the faucet with the same mild cleaner and a soft cloth, then rinse it well.
Don't skip the hidden-spot test
Finishes vary, and a cleaner that's safe on one sink can dull another. A short test on a hidden area costs far less than a dull patch on the basin.
When to call a professional
For dull or scratched acrylic, contact the manufacturer's customer service for repairs. Improper care and cleaning can void a cast iron warranty, so check the warranty before you use anything stronger.
Questions
Why do water stains keep coming back on my sink?
Water that dries on the surface leaves its mark again each time, so the best prevention is drying right after rinsing. Use a clean wipe or an air blower at the end of each use.
Can I use a stronger cleaner on a porcelain sink?
Only after the mild method has failed, and only if the cleaner's label says it suits your sink's material. A harsher product can dull a porcelain finish, so check its limits before you try one.
Why are my tap water stains red, pink or brown?
Colored rings on a sink can come from the water supply, and the color alone doesn't tell you which cause it is. Start with the mild cream cleaner method and see whether the color lifts. If it doesn't, don't go stronger until you've checked the limits for your sink's material.
How do I clean a black sink without leaving marks?
Use the mild cream cleaner on a soft cloth, rinse with clean water, and dry fully so no marks form. Test a hidden spot first, since color alone doesn't tell you what the sink is made of.
How do I know what my sink is made of?
Check the manufacturer's label or paperwork first, because the method depends on the material. If you still can't tell, use only the mild cream cleaner and test a hidden spot before going further.
Why does my stainless sink still look dull after cleaning?
A dull patch that stays after the mild method usually means the finish is already worn or scratched, and more scrubbing can make it worse. Rinse and dry it fully, then hold off on stronger products, since more scrubbing can worsen the dull patch.
