- Scrape off any excess paste with a dull knife, without forcing it deeper.
- Rinse with cool or cold water to dilute the stain.
- Blot rather than rub.
- Don't dry or iron until the mark is gone.
Toothpaste on carpet is tricky because the abrasive paste and its dye sink down between the tufts and the backing. Fresh marks lift with a mild detergent solution and a rinse, but paste left for days may need repeat treatment and still leave a shadow. Carpet is one surface where bleach and solvents can do lasting damage, so the whole approach stays gentle.
Blot with a white cotton cloth rather than rubbing, since rubbing pushes the paste deeper into the tufts. Blue or black gel paste often needs a second pass before the color lifts. If a shadow stays, reach for a carpet spot cleaner, and call a professional if it still shows.

5 steps
Step by step
Step 1 of 5
Scrape off the excess paste
Lift away any paste that sits on top of the carpet with a dull knife or spatula. Work from the outside of the mark toward the middle so the paste doesn't spread.
Careful. Pressing hard pushes the paste deeper into the pile, so keep the blade light.
Step 2 of 5
Mix the detergent solution
Stir 1 teaspoon of mild dishwashing detergent into 1 cup of warm water until evenly mixed. Dip a clean cloth or sponge in the solution and wring it out before it touches the carpet.
Careful. Bar soap and soap flakes can make this tannin stain harder to remove, so use only the dishwashing detergent.
Step 3 of 5
Sponge the stain with the solution
Blot the stain with the damp cloth, working from the edge toward the center. Use small amounts of solution and blot rather than rub.
Step 4 of 5
Rinse with cool water and blot
Sponge the area with clear, cool water until the cloth lifts no more color. Then blot thoroughly to pull out the excess moisture.
Step 5 of 5
Set the pile and let it dry
Once no mark is left, run your hand across the carpet against the nap to set the pile. Then let the area air dry completely before anyone walks on it.

Best products for toothpaste on carpet & rugs
Choose a mild liquid dishwashing detergent for the cleaning solution. For a stubborn mark, use the 3% hydrogen peroxide sold in drugstores, not the stronger hair-bleaching strength.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on carpet & rugs, 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
Every press should lift some tint onto your white cloth, and the spot should look lighter after each round. Once the cloth comes up clean but a faint outline lingers when the carpet is dry, move on to the set-in steps.
What changes for yours
Adjust for your carpet & rugs
Colored toothpaste
Colored toothpaste follows the same steps, since the dye is what leaves the mark. Scrape, sponge with the detergent solution, rinse with cool water and blot as usual. Don't rush the rinse, since a colored tint is easy to miss while the carpet is still damp.
If a tint stays after the carpet has dried, use the peroxide treatment for dried paste.
Gel toothpaste
Gel toothpaste follows the same steps, but scrape up as much of the gel as you can first, since it spreads when pressed. Work from the outside of the mark toward the center and keep the solution light.
If the gel has dried into the carpet, move on to the peroxide treatment, because a dried mark needs more than the basic steps.
Blue toothpaste on white carpet
Blue dye shows most on white carpet, so keep rinsing and blotting until the cloth comes away with no blue on it. Check the carpet in good light after it dries, before anyone walks on it.
If a blue tint stays, use the 3% hydrogen peroxide treatment for dried paste, and don't reach for a stronger product to chase the last of the color.
Wool carpet
Wool carpet gets the same gentle steps, with small amounts of solution and as little rubbing as possible. Use only the mild dishwashing detergent solution and clear water, and never use oxygen bleach or chlorine bleach on wool.
If the spot changes color or the wool looks different after cleaning, stop and call a professional carpet cleaner.
Old, dried or set-in stains
Stains get harder to remove the longer they sit, so an old mark needs patience more than force. Begin with the scraping and detergent steps again, rinsing and blotting until the carpet stops lifting color.
Dried paste is the hardest to lift, so the peroxide treatment is the next step. Test 3% hydrogen peroxide on a hidden spot first, then moisten the tufts with it and let it sit for one hour before blotting.
If the carpet has been through a dryer, the heat has likely set the mark, which makes it harder still. Repeat the peroxide treatment, and once it's clearly gone, let the carpet dry in open air. If the mark is still there after repeated rounds, call a professional carpet cleaner rather than trying stronger products.

Do home remedies work on toothpaste on carpet & rugs?
Most home remedies for toothpaste don't belong on carpet, so stick to the few that suit it. The main job falls to mild dishwashing detergent, and 3% peroxide is only for marks that stay behind.

What makes it worse
Mistakes to avoid
Don't spray a strong household cleaner on the spot
Strong household cleaners are too harsh for carpet, even when the mark looks stubborn. Stick to the mild detergent solution and clear water.
Don't pour solvent straight onto the carpet
Solvents can dissolve carpet materials and destroy the backing. If you want to try one, dab a few drops on a white cloth and never pour it onto the stain.
Don't push the paste deeper
Pressing a knife into the pile forces the paste down past the tufts, where it's much harder to reach. Lift the excess off the surface with a dull edge held almost flat instead.
Don't dry the spot with heat
A hair dryer, heater or other heat source can set the colorants before the mark has fully lifted. Let the carpet air-dry once the spot is gone, and keep people and pets off it until then.
Don't let the paste sit overnight
The longer toothpaste stays in carpet, the more its dye settles into the pile and the harder it is to lift. Treat it the same day, because a mark that sat for days usually needs a second full round.
When to call a professional
Call a professional carpet cleaner if a pretested cleaner changes the carpet's color, or if the mark is still visible after the set-in steps. Tell them it's toothpaste, roughly how long it sat, and list every product you put on it, since they'll need that to plan the next step.
Questions
Does mouthwash stain carpet?
Yes, mouthwash can leave a mark on carpet. Treat it the same way as toothpaste: scrape off any residue, sponge with the mild dishwashing detergent in warm water, then rinse with cool water and blot.
Can I use vinegar on a toothpaste stain?
No, skip vinegar; a mild detergent solution and clear water are what this carpet can take. Stick to the mild detergent solution and clear water, which is what this carpet can take.
What if the mark is still there after I've cleaned it?
Don't dry the carpet yet. Repeat the sponge and rinse steps, then move on to the 3% hydrogen peroxide treatment if a mark still shows.
Is it safe to use oxygen bleach on toothpaste on carpet?
No, skip oxygen bleach on carpet; it needs testing first and isn't safe for wool. Oxygen bleach needs testing first, and it's not safe for wool, so skip it on wool carpet.
Will toothpaste come out of carpet if it's been there for days?
It can, but it gets harder the longer it sits. Start with the steps above, then move to the peroxide treatment for dried paste.
Can I run a carpet steam cleaner over a toothpaste spot?
Not while any paste is still in the fibers, because heat can lock the colorants in place and leave a mark that won't budge. Once the spot is fully gone, you can clean the whole area as usual, though a large or stubborn mark may need a professional's hot water extraction.
Can I put laundry detergent on a toothpaste spot in carpet?
No. Those products often include bleaching agents, which can strip the color out of carpet fibers, so keep them off the spot entirely. Mix one teaspoon of a mild dishwashing detergent into one cup of warm water instead, and test it on a hidden patch first.
How do I dry the carpet once the toothpaste spot is clean?
Press a stack of dry white cloths onto the damp area and swap them out as they soak through. When the spot stops taking up moisture, rub your hand across the carpet against the nap to set the pile, and let it dry completely.
