- Pick off large pieces of putty by hand before you reach for anything else.
- Chill soft putty with ice cubes so it hardens, then scrape off as much as you can with a dull knife or spoon.
- Dried putty can often be pulled off, so scrape gently with a dull-edged knife or plastic card.
Plumbers putty left on a sink smears easily, because it's oily and waxy rather than solid. Fresh putty lifts with a dull knife and warm soapy water, but rushing it only spreads a greasy film. What's realistic depends on the sink, since porcelain, acrylic, enameled cast iron and stainless each handle cleaners differently.
Getting putty out of a sink drain without damage starts with a plastic scraper, since steel can chip porcelain or enameled cast iron. Acrylic scratches easily, so keep scouring cleansers off it and work slowly. On stainless, a melamine eraser used lightly can clear the last film once the bulk of the putty is off.

5 steps
Step by step
Step 1 of 5
Scrape off the loose putty
Chill soft putty with ice cubes until it hardens, then scrape it with a dull knife or spoon. Dried putty can often be pulled off by hand or lifted gently with a plastic card. Keep the pressure light so the surface isn't marked.
Careful. Don't scrape with a sharp blade, which can scratch the surface.
Step 2 of 5
Prepare a warm soapy towel
Dampen a few paper towels with warm water, then apply liquid dish soap until they're evenly soapy. Wring them so they're damp rather than dripping, which keeps the soap where you want it.
Step 3 of 5
Work the putty loose
Work the soapy towel over the area in a circular motion to loosen and lift the putty. Keep going until the putty is gone or the towel stops picking anything up.
Tip. Move to a clean section of towel as it fills so you aren't spreading putty around.
Step 4 of 5
Spray and wipe the residue
Spray the leftover residue with the all-purpose cleaner, then wipe it away with paper towels. Rinse the area with clean water and dry it with a soft cloth.
Careful. Don't let cleaner soak on the surface; rinse it off right away and wipe any overspray from nearby surfaces.
Step 5 of 5
Erase what's left
If a trace still shows, rub it with an eraser sponge, following the manufacturer's directions. Repeat as needed, then rinse and dry the sink.
Careful. Never use abrasive cleaners without water, and skip the eraser on acrylic and cast iron.

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.

The putty lifts off in pieces or wipes away cleanly, and the sink feels smooth when you run a finger over it. If the area still feels tacky, go back to the soapy towel before you move on.
What changes for yours
Adjust for your sinks
Porcelain sink
Porcelain takes the same soapy towel and cleaner steps, with one change: keep the eraser light and wet. Skip any ammonia-based spray, since it can damage the finish.
If the glaze looks duller after the eraser, stop, rinse, and use only the soapy towel on the next pass.
Acrylic sink
Acrylic is the most limited surface here, so leave out the eraser sponge and anything harsh. Use the warm soapy towel first, then the all-purpose cleaner only if the soap leaves a film, and rinse well.
If the surface stays scuffed or dull after this, it needs the manufacturer's repair rather than more scrubbing.
Enameled cast iron sink
On enameled cast iron the eraser is off the table, so stick to the soapy towel and the cleaner spray. Keep the area wet while you work and rinse thoroughly so nothing is left to dull the finish.
Rust spots need their own treatment, so don't use this method to chase them.
Stainless steel sink
Stainless has its own care rules, so check the Stainless Steel & Appliances guide before using any cleaner on it. Start with the warm soapy towel while you read it, since that's the gentlest method here.
If the stainless finish looks marked after cleaning, the guide will tell you which polish or wipe is right for it.
Old, dried or set-in stains
Old plumbers putty that has sat for a long time can be harder to lift, but the same steps still apply. Start with the chilling and scraping, then go through the soapy towel once more before anything stronger.
Once it's dried, putty often pulls off in one or two pieces if you work from the edge inward with a dull blade. Spray the residue and wipe it straight away, then rinse.
If a trace is still there, repeat the soapy towel and cleaner, then use the eraser sponge with water on the spot. Stop once the surface feels smooth and the finish looks even, because more pressure won't lift what's left and can dull the finish. Some very old, hardened residue may not come off completely, and that's realistic.

Do home remedies work on slime and putty on sinks?
Most household remedies are either unnecessary here or not a safe fit for every sink. The method above uses only warm soapy water, an all-purpose cleaner and an eraser sponge, which covers what a sink can take.

What makes it worse
Mistakes to avoid
Don't use solvents on your sink
Solvents aren't safe on acrylic, cast iron or vitreous china, which are common sink materials. Leave the rubbing alcohol, acetone and amyl acetate out of this job, even if the putty seems stubborn.
Don't use ammonia cleaners on porcelain
Ammonia can damage the finish on vitreous china, so read the label of any spray before you use it. The all-purpose cleaner in the steps above is the only spray this method needs.
Don't scour cast iron with steel wool
Steel wool, wire brushes and abrasive pads all scratch enameled cast iron. Stay with the towel and the cleaner spray, and rinse well so nothing dulls the finish.
Don't use aerosol sprays on acrylic
Aerosol cleaning products are a poor fit for acrylic, and abrasive cleansers are off limits too. A soft cloth, warm soapy water and a light cleaner rinse are all you need.
When to call a professional
If the sink has a deep scratch or a dull, rough patch that doesn't clear, a professional or the sink maker's repair service is the right call. Acrylic in particular needs manufacturer repair for dull or scratched areas, and a cast iron warranty can be voided by improper cleaning.
Questions
How to remove putty from a sink drain without damage?
Start by scraping off the bulk with a dull knife, since the drain is the hardest spot to reach. Use the soapy towel and wipe gently around the drain, and don't force a blade into the joint. If putty is still in the drain itself, skip solvents and sharp tools and work only with soap and water.
Can putty that has hardened in the sink still come out?
Often yes, because dried putty can usually be pulled or scraped off in pieces. Work from the edge, use the towel and cleaner, and expect a trace to remain on very old residue.
Does the soapy towel method work on a porcelain sink?
Yes. Warm water and dish soap are a gentle start on porcelain, and the eraser sponge is fine as long as you keep it light and wet.
What should I do on an enameled cast iron sink?
Skip the eraser sponge and any steel wool, and keep to the soapy towel and cleaner spray. Rust is a separate problem that this method won't fix.
Can I use bleach to remove putty from a sink?
No, leave it out. Chlorine isn't needed for putty, and it doesn't suit every sink material. Warm soapy water and the all-purpose cleaner will do the job without it, and they're less likely to leave the finish looking dull.
Do I need to rinse the sink after cleaning?
Yes. Rinse after each use and dry with a soft cloth so no cleaner is left sitting on the surface.
How do I know what my sink is made of?
Check the manufacturer's label or the sink's model information first. If you still can't tell, use only warm water, dish soap and the all-purpose cleaner, and skip the eraser and any solvent.
