- Scrape or blot off the excess; don't rub.
- Rinse with cold water from the back of the stain.
- Don't use bar soap on fruit stains; it sets them.
- Keep it out of the dryer until the stain is gone.
Smoothies on carpet are harder than they look, because one drink can hold two different stains. Fruit and juice can set and turn yellow or brown if they sit, while milk, yogurt or protein powder needs cool water before anything else. A fresh spill usually lifts, but the longer it waits, the more likely you are to be left with a shadow that only fades over time.
Start by blotting green smoothie out of carpet with a clean white cotton cloth, pressing from the edge toward the middle. Banana smoothie usually needs a second pass with a carpet spot cleaner, so don't rush the rinse. If the mark still shows once it's dry, call a carpet cleaner rather than scrubbing it harder.

Step by step
Step 1 of 6
Scrape or blot the excess
Start with the thickest bits first, lifting any semi-solid smoothie with a rounded spoon or dull knife. Then blot the liquid with a dry white cloth or plain white paper towels. Work from the edges toward the center, and don't rub.
Step 2 of 6
Blot with cold water
Dampen a clean white cloth with cold water and blot the spot from the edges inward. Keep the cloth wet but not dripping, and don't saturate the carpet.
Careful. Don't start with hot water when the smoothie has dairy or protein in it.
Step 3 of 6A few minutes
Work in the mild detergent solution
Mix 1/4 teaspoon clear liquid hand dishwashing detergent into 1 cup lukewarm water, and never make it stronger. Test it on a hidden spot first, then apply it to a white cloth and work it gently in from the edges. Let it sit a few minutes, then blot, and keep going as long as color transfers to the cloth.
Step 4 of 6
Rinse out all the detergent
Mist the spot with lukewarm or cold water from a mist sprayer, blotting after each rinse. Repeat until no detergent is left, because leftover detergent makes carpet resoil faster.
Step 5 of 6
Treat what's left with vinegar
If a mark still shows, pretest and then apply a solution of 1 cup white vinegar to 2 cups water. Rinse with water and blot again to clear the vinegar out.
Step 6 of 6
Dry under weighted white towels
Cover the spot with layers of white towels and weigh them down with a heavy colorfast object. Change the towels until the carpet is dry, and if the spot comes back as it dries, blot out the moisture and repeat the steps.

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 blot should pick up a little color onto your white cloth, and the spot should look lighter with each round. Once the cloth stays clean, watch the carpet as it dries, because a stiff or sticky feel means residue is still in the pile. A yellow or brown tint that won't lift after several cold rinses is the sign the stain has set.
What changes for yours
Adjust for your carpet & rugs
Green smoothie
If the green smoothie has milk, yogurt or protein powder in it, the cold water blot is the right start, since it's a dairy or protein stain as well as a fruit one. Leafy greens make the green tint easy to see on light carpet, so check the spot against the carpet around it before you call it finished.
Keep blotting with the white cloth during the detergent step, because the color shows up on the cloth as it lifts. If a faint green tint stays after the rinse, the vinegar step is the next one to use.
Banana smoothie
Banana turns the smoothie thick and pulpy, so scraping comes before any liquid touches the carpet. Use a rounded spoon or dull knife to lift the bulk, then blot what's left with a dry white cloth.
Banana pulp can leave a sticky film, so give the rinse step extra passes until the cloth comes away clean. Then work through the detergent and rinse steps as written, and watch for a leftover tint once the spot is dry.
Old, dried or set-in stains
An older smoothie stain is harder to lift than a fresh one, and fruit that has dried on the carpet can turn yellow or brown. Work through the steps from the top, using the same light touch.
Once the spot has dried, the peroxide option is the stronger step: moisten the tufts with 3% hydrogen peroxide, let it sit for one hour, blot, and repeat. Pretest it in a hidden area first, and don't use anything stronger than 3%.
If the carpet went in the dryer before the stain was gone, heat may have set the mark, so check it again after cleaning. Some faint tint may still remain on an old spot, and that is a realistic result. If the color changes or the mark won't lift, stop and have a professional look at it.

What makes it worse
Mistakes to avoid
Don't pour solvent or alcohol on the carpet
Solvents can dissolve carpet materials and destroy the backing, and a pour puts all of that into one spot. Stick to the water, detergent and vinegar steps on this stain instead.
Don't blot with the same wet patch of cloth
Each blot lifts stain onto the cloth, so putting that section back on the carpet puts the stain back. Fold the cloth to a clean, dry section every time.
Don't wait until the next day
A smoothie left overnight is harder to lift than one you handle right away. Even partial cleaning now beats leaving the spot until morning.
Don't rinse a dairy smoothie with warm water
Warm water can set the dairy and protein into the fibers, so every rinse should be cold or lukewarm. Stick with that even when the first pass looks stubborn.
Don't skip the detergent rinse
Leftover detergent makes carpet resoil faster, and a smoothie spot can look clean right before it darkens again. Rinse several times with a mist sprayer, blotting after each pass, until no soap comes up.
Don't dry the spot with a hot hair dryer
A hair dryer can feel quicker, but heat can set the stain before it is gone. Let the spot dry under weighted white towels, changing them until the carpet is fully dry.
When to call a professional
Call a professional carpet cleaner if a pretested solution changes the color of the carpet, if an oily residue stays after rinsing, or if the spot is large enough to need hot water extraction. Tell them it was a smoothie with dairy or protein, how long it sat, and every solution you've tried.
Questions
How do you get protein shake smell out of carpet?
Remove every trace of the shake first, since leftover residue is what keeps the smell in place. Rinse out the detergent completely and let the spot dry fully, without heat, before you judge the odor. If the smell is still there once it's dry, repeat the cleaning steps once more.
Can a smoothie stain set if it sits overnight?
It can. Fruit that dries on carpet can oxidize to yellow or brown, which makes the stain harder to lift. Blot it as soon as you can, even if you can't finish the steps right away.
Can I mix vinegar and detergent in one bottle?
No, keep them apart. Use the detergent solution, rinse it out completely, and only then apply the vinegar solution, so the two never meet in the carpet. Chlorine bleach is never part of this.
What if I don't know what my carpet is made of?
Start with the cold water blot and the mild detergent solution only, and pretest them in a hidden spot. Leave out bleach and solvents entirely, since you can't confirm the fiber can take them. If the spot doesn't lift, the set-in step is the next thing to try.
Can I use a store stain spray on a smoothie stain?
You don't need one, so skip it. If you still want to try one, check the label for carpet and pretest it in a hidden area first. If you still want to try one, check the label for carpet, pretest it in a hidden area, and follow the directions exactly.
Can I run a carpet steam cleaner over a smoothie stain?
Skip the steam while the smoothie is still in the pile, because heat can set the dairy and fruit into the fibers. Blot and rinse by hand with cool or lukewarm water instead, and save hot extraction for a professional handling a large or stubborn patch.
Is it safe to use laundry or dishwasher detergent on a smoothie?
No. Both can contain bleaching agents or alkalis that strip carpet dye and may set some stains, so keep them out of the mix. A mild detergent with no bleach, used sparingly in lukewarm water, is the safer choice, and you should test it on a hidden corner first.
How do I dry the spot once the smoothie is gone?
Lay several layers of white towels over the damp area, weigh them down with something heavy and colorfast, and swap them out as they soak up moisture. Keep at it until the carpet is completely dry, since any moisture left in the backing can wick the stain back to the surface.
