- Blot with a clean, dry white cloth or paper towel. Don't rub it.
- Sponge the spot with cool water if you can do it right away.
- Keep heat away: no dryer, iron or hot air until the stain is gone.
- Test any cleaner on a hidden spot first, and stop if color transfers.
Coffee on wool is a tannin stain, and if it had cream or milk in it, the greasy part has to be treated first. Wool can't take heat, hot water or scrubbing, so every step has to stay gentle. A fresh spot often responds to a light touch, but an old stain, or one that has already been through the dryer, may only partly lift and sometimes won't respond at all.
Treat a coffee stain on a wool sweater with cool water and a little delicate detergent, dabbing rather than rubbing. Cashmere and merino need the same gentle handling, so keep the fibers from being pulled or stretched. Stop as soon as the coffee stops lifting, since pushing harder only roughs up the wool.

Step by step
Step 1 of 6
Blot up the excess
Press a clean, dry white cloth or white paper towel onto the spot to soak up the liquid. Keep pressing with fresh sections until little more comes up.
Tip. Fold the towel so each press uses a clean part.
Step 2 of 6
Mix and work in the detergent
Stir 1 teaspoon of mild detergent into 1 cup of lukewarm water. Work small amounts of the solution into the pile with your fingertips, then blot.
Careful. Keep the water lukewarm, about 30°C; never use hot water.
Step 3 of 6
Rinse the spot with water
Flush the area with clear water to carry the detergent out. Blot again until the cloth comes up clean.
Step 4 of 6
Dab with the vinegar solution
Mix 1/3 cup of white household vinegar with 2/3 cup of water. Blot the stain with a clean absorbent cloth dampened with this solution.
Careful. Use white vinegar only; colored vinegar can leave a stain.
Step 5 of 6
Sponge with clear water
Sponge the area with clear water to carry out the vinegar, so none of it is left in the fibers to dry on. Blot again until the cloth comes up clean, and don't let the spot stay wet.
Step 6 of 6
Dry it flat under a weight
Lay a 1/2 inch layer of dry absorbent material over the area and weight it down with a book. If that material gets wet, swap in dry material and leave it for several hours, then brush the area with your hand to restore the pile.

Best products for coffee on wool & cashmere
A mild liquid detergent sold for hand washing wool is the right type of product for the solution in this method. Check its ingredients for natural soap before you use it.
Woolite Delicates
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on wool & cashmere, 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 before using any heat. 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
Each blot should lift a little more coffee onto the cloth, and the spot should look paler with every round. If it stops lifting after the vinegar and the rinse, let it dry flat and check it before you try anything stronger.
What changes for yours
Adjust for your wool & cashmere
Wool Sweaters
Work on the sweater while it lies flat, with a towel underneath so the coffee can't soak through to the other side. Go gently around the knit so you don't stretch it.
Squeeze the spot out instead of wringing it, and dry the sweater flat on a towel, away from radiators and direct heat.
Cashmere
Cashmere is finer than ordinary wool, so use the same steps with a lighter hand. Squeeze gently rather than wringing, and never tumble dry it.
Test the detergent and vinegar solutions on a hidden spot first, and if color moves, take the sweater to a professional. Woven cashmere is also a job for a professional cleaner.
Wool Sweaters and Other Wool Clothes
Check the care label before anything wet touches the fabric. Wool is hand washed in lukewarm water, and it goes in the tumble dryer only if the label says so, on a low or wool setting.
Keep the work to the spot so the rest of the garment doesn't get soaked. If the label says dry clean only, skip home treatment and take it straight to a professional.
Merino Wool
Merino is wool, so the steps above apply, and it pays to be even gentler because the fibers are fine and soft. Keep the water lukewarm and the work short so the fibers don't felt.
Check the care label first, since a merino piece marked dry clean only should go to a professional. Otherwise, use the wool steps and dry it flat.
Old, dried or set-in stains
An old coffee stain is harder to remove than a fresh one, and some won't respond at all. Repeat the detergent and vinegar steps, rinsing between each round, and hand wash in lukewarm water with a mild detergent, soaking the sweater for about 10 minutes.
A stain that has dried in the dryer may be impossible to remove, because the heat sets it. Treat a dried stain the same way, patiently, and keep the sweater away from heat until you're finished.
If the stain is still there after a few rounds, stop before it damages the fibers. On an old or heirloom sweater, a long-standing stain has often weakened the fibers, and forcing it out can leave a hole, so a professional is the safer call.

Do home remedies work on coffee on wool & cashmere?
Most common kitchen remedies don't suit wool, so only gentle options that wool can take are worth using. Here is how each common remedy measures up for coffee on wool.

What makes it worse
Mistakes to avoid
Don't use bar soap on the stain
Natural soap, from bar soap to soap flakes, makes a tannin stain harder to remove. Stick to the mild detergent in the steps.
Don't use bleach or enzyme products on wool
The product labels for chlorine and oxygen bleach say not to use them on wool, and enzyme detergents are not meant for wool. The mild detergent and white vinegar steps are the safe route.
Don't tumble dry wool unless the label says so
Wool shrinks and felts with heat and tumbling, so the dryer is only for garments labeled tumble dry, on a low or wool setting. Never tumble dry cashmere.
When to call a professional
Take it to a professional cleaner if the label says dry clean only, or if a spot test shows color transfer. Dry cleaning is also the preferred choice for wool because it limits shrinkage, and a stain that remains after home treatment is worth a professional look.
Questions
Can I put a coffee-stained wool sweater in the washing machine?
It's safer to hand wash, since machine agitation can felt and shrink wool. If the label allows a machine wool cycle, use lukewarm water only, never hot, and dry the sweater flat afterward.
Which coffee stain remover is safe for wool?
The safest choice is a mild detergent made for hand washing wool, used in the lukewarm solution described above. Skip any spray or powder whose label says not to use it on wool.
Does milk or cream change how I treat the stain?
Yes, the dairy adds a greasy part that should be tackled first. Scrape off any dried cream gently, and if the spot still feels greasy, a solvent such as white spirit can go on after a test on a hidden spot.
Can I wash a cashmere sweater the same way?
Yes, with a lighter hand: use the same lukewarm steps, squeeze instead of wringing, and never tumble dry it. If the spot shows color transfer or the knit is woven, take it to a professional.
Can coffee permanently stain wool?
It can, especially once heat has set it. Blot it quickly, and keep the sweater out of the dryer until the stain is gone.
Can I use vinegar on a bright or colored sweater?
Only after a hidden-spot test, because white vinegar can change the color of some dyes. Use white vinegar only, as the steps say.
