First few minutes
Just happened? Do this first
- Check the mark in good light: pale browning is worth a try, black char usually isn't.
- Start with a soft, damp cloth before any cleaner touches the spot.
- Put steel wool and abrasive pads aside for now.
- Put on rubber gloves if you reach for anything strong.
Scorch on a sink is heat damage to the surface itself, so a scrub won't lift it the way it would a food stain. Light yellow or brown scorching sometimes comes out with gentle cleaning, but charred spots usually stay. Test any cleaner on a hidden spot first, and work out which kind of burn you have before you scrub.
Yellow burn stains in a porcelain sink usually respond to a mild scouring cleanser, so start there before reaching for anything stronger. Stop as soon as the shine starts to fade, because more rubbing will only make it worse. When you're cleaning a burn stain on an acrylic sink, a rough pad can leave dull patches, so use a soft cloth.

7 steps
Step by step
Step 1 of 7
Judge the damage first
Look at the mark in good light and decide whether it's light browning or real charring. Light browning sometimes lifts with the steps below, but charred or deep burns usually can't be removed, and scrubbing them can make things worse.
Step 2 of 7
Test on a hidden spot
Pick an inconspicuous spot, like the inside edge of the basin, and try the cleaner there first. Include any bleach or hydrogen peroxide in that test before you use it on the stain.
Step 3 of 7
Wipe the sink down
Wipe the stained area with a soft, damp sponge or cloth to clear surface grime first. On porcelain or vitreous china, a little mild soap and warm water is enough for this pass.
Tip. Rinse the sponge often so you aren't dragging grit across the surface.
Step 4 of 7
Clean heavy soil with a labeled cleaner
If the sink is still dirty, work a general-purpose cleaner labeled for your sink material over the area. Put on rubber gloves and keep the room ventilated, since you're working with strong chemicals.
Step 5 of 7
Rinse right away
Rinse the area completely with water as soon as the cleaner has done its work, so none of it sits on the surface. Rinse any overspray off the nearby surfaces too.
Careful. Don't let any cleaner soak on the surface.
Step 6 of 7
Treat a stubborn stain
On enameled cast iron or vitreous china only, a soft abrasive cleaner can be used sparingly, always with water. For a mark on enameled cast iron, a cast-iron cleaner made for enamel removes marks and restores shine.
Careful. Never use an abrasive cleaner without water, and never on acrylic.
Step 7 of 7
Blot the sink dry
Blot the area dry with a soft cloth so the finish is left clean. Then look at the mark in the same light you used at the start.

Best products for scorch on sinks
Choose a general-purpose cleaner labeled for your sink's material, and a cast-iron cleaner made for enamel if your sink is enameled cast iron.
Amazon Basics Microfiber Cleaning Cloths
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
A light mark should fade as you wipe and rinse, and the surface should look even once it's dry. If the mark is unchanged after a full pass, it has most likely become part of the surface, and more cleaning won't bring it back.
What changes for yours
Adjust for your sinks
Burn on a porcelain sink
Porcelain and vitreous china are the most forgiving here, and the gentle steps work as written. Start with mild soap and warm water, and only move to a soft abrasive cleaner if the mark is still there, always with water.
Don't let any cleaner sit on the glaze, and rinse thoroughly before you judge the result. A mark that's still dark after two careful passes is probably permanent.
Cleaning burn on an acrylic sink
Acrylic is the one sink where you skip abrasives and solvents completely. Use a soft cloth with a general-purpose cleaner labeled for acrylic, and rinse right away.
Cleaning can't fix dull or scratched acrylic, so that's a separate job. Work slowly and check the spot in good light between passes.
Old, dried or set-in stains
An old burn has usually changed the surface itself, and no cleaner will bring the original finish back. Light browning on porcelain or enameled cast iron is the kind that sometimes lifts with a second pass.
For rust on enameled cast iron, a rust remover made for enamel is the stronger option, used only on the rust and rinsed well. Once the stronger product is rinsed away, the sink should be dried with a soft cloth.
If the stain still shows after that, accept that it's permanent, since deep discoloration rarely goes away fully. Don't keep escalating, because each stronger pass adds risk to the finish.
Vinegar, baking soda, peroxide and more
Do home remedies work on scorch on sinks?
Plenty of home remedies float around for burn marks, but most are built for fabric or wine rather than a sink's finish. Start with a soft cloth and a labeled cleaner, and skip most of the rest.

Chemical safety
Never mix these
Some products in this guide react dangerously with each other. Use them one at a time and rinse with water in between.
Chlorine bleach + Hydrogen peroxide (3%)
Washington State's health department says bleach reacts with hydrogen peroxide, and Clorox says not to mix bleach with other household chemicals.
If they mix by accident: Don't use the mixture; ventilate the room and avoid breathing fumes or touching it; call Poison Control at 1-800-222-1222 for disposal advice or if anyone feels unwell.
What makes it worse
Mistakes to avoid
Don't scrub with steel wool or abrasive pads
Steel wool, wire brushes and abrasive pads can scratch enamel and leave cast iron dull. Sanding can damage the finish too, so stick to the soft cloth and the cleaners listed above.
Don't use ammonia on porcelain
Ammonia cleaners can damage the finish on vitreous china. A mild soap or a general-purpose cleaner labeled for your material is the safer choice.
Don't reach for solvents
Solvents are off the list for acrylic, cast iron and vitreous china. If a cleaner's label names one, put that bottle back on the shelf.
Don't spray aerosols on acrylic
Aerosol products are a poor fit for acrylic, so use a cloth and a liquid cleaner labeled for acrylic instead. Acrylic is the surface where a simple kit works best.
When to call a professional
If the burn is charred or deep, a professional repair is the realistic option. For dull or scratched acrylic, the manufacturer's customer service is the right contact, since repairs are safer left to them.
Questions
Can you remove a burn mark from a sink?
Light browning often can, using the gentle steps above. Charred or deep burns usually can't be removed, and scrubbing harder won't change that.
What's the difference between a yellow burn and a charred one?
A yellow or light brown scorch is surface discoloration that a gentle clean can sometimes lift. A charred mark is damage that has gone deeper, and it usually stays.
Can I use bleach on my sink?
Only as a tested last resort: try it on a hidden spot first, and rinse the sink fully before you use it. Never leave it on a spot that holds ammonia, lemon juice or vinegar from another method, and rinse and wash in between.
How do I treat a burn on enameled cast iron?
Start with the wipe-down, then move to the cast-iron cleaner made for enamel if the mark stays. Rust on this surface is a separate job, handled with a rust remover made for enamel.
Will cleaning a burn void my sink warranty?
It can, if the cleaning is improper or the care terms are ignored. Check the warranty's care section before you use any cleaner beyond a soft cloth and mild soap.
What if I don't know what my sink is made of?
Treat it as acrylic until you know otherwise: a soft cloth, mild soap and warm water, and a cleaner labeled for acrylic only. That keeps you away from abrasives and solvents, which can damage any of the common sink materials.
