- Scrape off any excess paste with a dull knife or spatula, without forcing it deeper.
- Rinse with cool or cold water to dilute the stain.
- Blot rather than rub.
Toothpaste on a sink leaves a white or colored mark, since the paste's dyes and detergents cling to the finish as they dry. The right cleaner depends on the sink's finish, because a glossy acrylic basin and a vitreous china one don't take the same treatment. A fresh mark usually wipes away, but an old one on dull or scratched acrylic may need a repair rather than more cleaning.
Figure out whether your sink is acrylic, enameled cast iron or vitreous china before you pick a cleaner for toothpaste stains from the sink. Scrubbing harder on an acrylic basin that's already worn only makes it look worse. If a dried mark around the drain won't budge after a few gentle tries, call a pro rather than pushing on.

5 steps
Step by step
Step 1 of 5
Scrape off the excess paste
Use a dull knife or spatula to lift off any paste sitting on the surface. Keep the blade flat and light so you don't push the paste deeper into the finish.
Step 2 of 5
Rinse with cool water and blot
Run cool or cold water over the area to dilute what's left. Then blot the wet spot with a cloth instead of rubbing it.
Step 3 of 5
Test, then wipe with a soft cloth
Test any cleaner on an inconspicuous spot first. Then wipe the mark with a soft, dampened sponge or cloth; on vitreous china, use a mild detergent and warm water.
Careful. Soap can make a tannin-type mark harder to remove, so leave it out.
Step 4 of 5
Use a general-purpose cleaner if heavily soiled
If the sink is still heavily soiled, use a general-purpose cleaner that's listed for its material, applied with a damp cloth. Rinse completely with water right after applying it.
Careful. Don't let any cleaner soak on the surface; rinse it off right away and wipe overspray from nearby surfaces.
Step 5 of 5
Rinse thoroughly and blot dry
Rinse the sink with water until no paste or cleaner is left behind. Once the mark is gone, blot the sink dry with a soft cloth.

Best products for toothpaste on sinks
Choose a general-purpose cleaner listed for your sink's material, and a detergent with no soap in its ingredients. Skip aerosol products on acrylic.

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.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The mark is gone when the surface looks even and clear, with no paste or colored film left and the rinse water runs clean. If a faint shadow remains after the first pass, repeat the scrape and wipe steps before trying anything stronger.
What changes for yours
Adjust for your sinks
Acrylic sink
Acrylic takes the least, so the wipe-down with a soft cloth and water does most of the work. Reach for a general-purpose cleaner listed for acrylic only when the mark is heavy.
Once you're done, check the surface in good light and stop there if the sink looks clean.
Enameled cast iron sink
Enamel can take a soft abrasive for a stubborn mark, and that's the main change from the steps above. Use it sparingly with water, and only after the gentle passes have failed.
For a mark that stays on the enamel, a cleaner made for enameled cast iron removes marks and restores shine. Rinse completely after each treatment, then blot dry.
Vitreous china sink
Vitreous china gets a mild wash: a detergent without soap and warm water for the wipe-down. A stubborn mark can take the soft abrasive, used sparingly and with water.
A light mark usually lifts with the wipe-down alone, so you rarely need the stronger steps here. Once the mark is gone, blot the sink dry.
Dull or scratched acrylic
Cleaning can't bring back the shine on acrylic that has dulled or picked up scratches. Keep to the gentlest wipe-down in the meantime.
Contact the manufacturer's customer service for repair, since that's the route for dull or scratched acrylic.
Old, dried or set-in stains
A mark that has been sitting for a while needs a second full pass, not a harder scrub. Repeat the scrape, rinse and wipe steps from the start, because stains left for days often need that. Then rinse well and look at the mark in good light before you go further.
If the mark is still there on enameled cast iron or vitreous china, a soft abrasive cleaner can help. It's the stronger option, so skip it until the gentle passes have failed, and use it sparingly with water. Rinse it off completely when you're done.
On enameled cast iron, a cleaner made for that finish removes marks and restores shine. A mark that survives all of this may be set into the finish, and at that point a professional cleaner is the realistic next step.

Do home remedies work on toothpaste on sinks?
Plenty of home remedies for toothpaste are written for fabric rather than sinks. On a sink, a soft cloth and a detergent without soap do the job, and solvents don't belong on it.

What makes it worse
Mistakes to avoid
Don't use abrasive cleansers on acrylic
They damage the surface, so acrylic gets a soft cloth and water instead. This rule still applies when the mark looks stubborn.
Don't scrub cast iron with steel wool or pads
Steel wool, wire brushes and abrasive pads all scratch enameled cast iron. Keep to a soft cloth, and save the soft abrasive for a stubborn mark.
Don't scrub dry with an abrasive
Any abrasive cleaner needs water with it, and strong abrasive cleaners scratch and dull vitreous china. Keep the soft abrasive for enamel or china, and use it sparingly with water.
Don't mix cleaners in the sink
Never mix chlorine bleach with vinegar, alcohol or ammonia. If you need a second product, rinse the sink thoroughly before you start with it.
Don't reach for solvents
Solvents aren't safe on acrylic, cast iron or vitreous china, so skip anything labeled as one. Alcohol-based products count too.
When to call a professional
If the mark stays after the stubborn-mark treatment, a professional cleaner is the realistic next step. For dull or scratched acrylic, contact the manufacturer's customer service for repairs.
Questions
Does toothpaste stain a sink?
Yes, it can leave a white or colored mark, since the colorants cling to the finish. It's easiest to lift while it's still wet, so start with the scrape and rinse as soon as you see it.
Can I use vinegar on my sink?
No, vinegar is unsafe on stone and cement grout, so use a mild detergent and a cleaner made for your sink's material. There's no sink amount for it, and it's listed as unsafe on stone and cement grout, so stick with a mild detergent and a cleaner listed for your material.
Can I use bleach on my sink?
Skip chlorine bleach unless you've checked that your sink's material can take it, since it isn't clearly suited to every sink. Leave it out unless you've checked that your sink's material can take it.
Can I use hydrogen peroxide on a sink?
No, peroxide isn't something to use on a sink. It's a fabric treatment rather than a sink one, so there's no sink amount or method to follow.
What if the mark is still there after cleaning?
Repeat the scrape, rinse and wipe steps, since a stain that has sat for days often needs a second full pass. If it's still there, a soft abrasive on enamel or china is the next step, and a professional is the option after that.
Why does my acrylic sink look dull after cleaning?
Cleaning can't restore a dulled acrylic finish, so the dullness is likely the surface itself. Contact the manufacturer's customer service for repair, and keep cleaning gentle until then.
Does mouthwash stain a sink the same way?
Mouthwash spills can leave a mark too, and they're handled the same way. Scrape or blot off what you can, rinse with cool water, then wipe with a soft cloth and rinse again.
