- Scrape off any solids with a dull knife.
- Check the care label before any water touches the item.
Oil stains are the hard ones on polyester, since heat from a dryer or iron can bake them into the fibers. Fresh marks usually lift with patient blotting and a detergent pretreat, but an old stain that has been dried or ironed in may only fade. A dry-clean-only label changes what you can safely attempt, so read it before you start.
Blot with cold water and don't scrub, since rubbing pushes the oil deeper into the weave. For a polyester shirt or dress, work a little detergent into the spot, let it sit, then rinse. If the mark survives a wash, keep it out of the dryer, because heat can set it for good.

7 steps
Step by step
Step 1 of 7
Blot up the excess liquid
Press a clean white cloth onto the stain to lift off any liquid, and don't rub. Then use a dull knife to gently scrape off solids, working from the edges toward the middle.
Step 2 of 7
Check the care label first
Find the fiber content and care symbols before you use water or any product. Dry-clean-only coats and jackets should go to a dry cleaner promptly, so skip the washing steps for them.
Step 3 of 7
Test a hidden seam first
Dab your chosen remover onto a hidden seam or hem and let it dry. If the color or finish changes, stop there, because that remover isn't safe for this item.
Step 4 of 7
Soak or spot-wash in water
If the whole item can be submerged, start with a cold-water soak, which is the safe first move for a stain you haven't identified. If it can't be submerged, dampen the stain with warm water and work on it with the spot treatment described below.
Careful. Synthetics are heat sensitive, so never use hot water on a stain you haven't identified.
Step 5 of 7
Work in liquid detergent and air-dry
Work heavy-duty liquid detergent into the stain with your fingertips, since it handles oily soils best. Rinse it out and let the item air-dry, then check the spot in good light.
Careful. Never machine-dry or iron a synthetic with an oil stain still in it, since removal may become extremely difficult, if not impossible.
Step 6 of 7
Spot-treat from the wrong side
If the stain is still there, lay the item wrong side up over a pad of clean towels so the stain has an absorbent backing. Work a pretreatment spray or dry-cleaning solvent into the stain, feathering from the outside in, then follow with an all-fabric (oxygen) bleach.
Careful. Skip acetone on acetate, triacetate or modacrylic, and let any dry-cleaning solvent evaporate before you wash or dry the item.
Step 7 of 7
Wash warm and air-dry to finish
Launder the item in warm water, but skip the warm wash if you're still unsure what the stain is, and check the mark while the fabric is still wet. Air-dry it until the stain is gone, since air-drying keeps the option to treat it again if it's still there.

Best stain removers for polyester & synthetics
Keep a heavy-duty liquid detergent for the first wash and an all-fabric (oxygen) bleach for whitening. Pick a pretreatment spray or dry-cleaning solvent for the spot step rather than a general household cleaner.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on polyester & synthetics, 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.
See what to do for what you're seeing →If the stain was already dried or set, the method changes.

No match. Try the main search for anything else.
How to tell it's working
The stain is gone when you can't see it in good light, both while the item is wet and after it has fully air-dried. If any shadow remains, treat that spot again before you move on.
What changes for yours
Adjust for your polyester & synthetics
Shirts, dresses, blouses, and clothing
Washable shirts, dresses and blouses follow the steps above as written. Give extra attention to collars, cuffs and underarms, where marks often sit.
Check the care label for each piece before you start. If the stain is on a button placket or a seam, treat it from the wrong side so the mark doesn't spread across the front.
White polyester
On white polyester, the all-fabric oxygen bleach in the stubborn-stain step is the whitening tool to use. Test it on a hidden seam first, and only use it on fabric that is colorfast.
Work the detergent and oxygen bleach slowly and check after each pass, so you don't overtreat one spot. Stop as soon as the stain disappears, because extra passes add wear without adding results.
Pure polyester
Pure polyester is the simplest case, and the steps above cover it in full with no changes to the water or the products. Use the same warm water, the same pretreat and the same air-dry check every time.
Don't assume the fiber from how the fabric feels; check the label. If it lists any other fiber, such as spandex, treat the item as a blend and read the blend card before you use bleach.
Couches and table linens
Table linens are washable, so the steps above apply to them as written. A couch is different, because the cushions and frame can't go in a washer and the whole piece can't be air-dried the same way.
For an upholstered couch, blot and scrape the stain, then take it to a dry cleaner if it is still visible, since bulky items are best handled by a professional. Blot from the surface only and don't press liquid deeper into the padding.
Fabric and material
Loose polyester fabric, such as yardage or a sewing project, follows the steps above as long as you can submerge or wash the piece. Test any remover on a scrap or a seam allowance before you treat the main piece.
Handle the cut edges gently during the scrape and the wash so they don't fray. Air-dry the piece flat rather than hanging it, so the cut edges keep their shape.
Blends with spandex, modal, or rayon
Spandex is the fiber to watch in a blend, since chlorine bleach isn't allowed on it. Check the label for spandex content before you reach for the oxygen bleach, and otherwise follow the steps above.
Modal and rayon are more delicate, so treat them with extra care. Stop after the warm wash and check the spot before you use any bleach on them.
Jackets, coats, and windbreakers
Start by checking the label, because many polyester jackets are washable and the steps above apply to them. If the label says dry-clean only, blot and scrape the stain, then take the jacket to a dry cleaner promptly. Synthetic insulated jackets need extra care, so don't dry-clean them or use fabric softener on them, since softener coats the fill and reduces warmth.
Air-dry the jacket fully before you decide the stain is gone. Check the seams and the lining too, since a mark can hide in either place.
Satin and ties
Satin and ties depend on their finish, and the finish is the part that shows damage first. Lay the item flat on a towel while you work, and keep the spot treatment to the stain itself rather than the whole area.
If the finish changes at any point, stop and take the item to a dry cleaner, since fragile fabric is one of the reasons to go there. Ties are usually small, so you can often do the whole job in a sink rather than a washer.
Dry-clean-only polyester
For dry-clean-only items, the blot and the label check are the only steps to do yourself. Scrape off solids gently, then take the item to a dry cleaner promptly and point out the stain.
Don't try the washing or the oxygen bleach at home, since the care label rules those out. Tell the cleaner what the stain is and what the fiber is, so they can choose the right process.
Old, dried or set-in stains
Stains that have been through a dryer or an iron are the hard case. Oil that has been dried or ironed into synthetic fabric may be extremely difficult, if not impossible, to remove.
For general yellowing or graying on a synthetic, rather than one specific mark, wash on a permanent press cycle in warm water with a cup of water conditioner in place of detergent. Finish with a cool-down rinse, then repeat, or use an all-fabric bleach if the color still hasn't improved.
If a mark is still visible after these tries, a dry cleaner is the next realistic step, and some oil stains won't come out at all.

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 + Oxygen bleach (OxiClean)
Both makers advise against combining them: OxiClean says not to mix it with chlorine bleach, and Clorox says the two bleaches cancel each other out.
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 the stain hard
Rubbing can spread the stain and damage the fiber, the finish or the color. Blot and press instead, and let the detergent do the lifting.
Don't mix stain removers
Especially ammonia and chlorine bleach, which should never be combined. Use solvents in a well-ventilated room, away from open flames.
Don't guess at the fiber
If the label is missing or you can't tell what the fiber is, skip the bleach and the remedies. Use a cold-water soak if the item can be submerged, and take it to a dry cleaner if you're unsure.
Troubleshooting
If the stain is still there
Pick what you're seeing:
A greasy-looking splotch appeared after drying
It may be fabric softener from a dryer sheet. Work liquid detergent into it and rewash.
The stain is still faint after washing
Don't dry it. Spot-treat from the wrong side again, follow with all-fabric bleach and rewash.
An old stain smells rancid
It is likely old oil. Treat it with heavy-duty liquid detergent and a solvent spot treatment, then wash.
A ring appeared around the treated spot
Feather the treatment from the outside edge inward next time, then rewash the whole garment.
When to call a professional
Take dry-clean-only coats and jackets to a dry cleaner promptly, and point out the stain and the fiber. Take washable items there too if the stain is large, the item is bulky or the fabric is fragile. Leather, suede or fur trim needs a leather or fur specialist.
Questions
Does polyester stain easily?
Polyester handles most water-based spills well. Oily stains are the exception, since they can bond to the fibers and set in when they dry or get ironed. Treat a fresh oily spill quickly, and most come out with the steps above.
Does rubbing alcohol stain polyester?
Not needed: rubbing alcohol can lift untested dyes, so test a hidden seam first if you try it. It can lift untested dyes from colored fabric, so if you try it anyway, test a hidden seam first.
Can I use chlorine bleach on white polyester?
No, skip chlorine bleach; an all-fabric oxygen bleach is the whitening choice after testing a hidden seam. For whitening, use an all-fabric oxygen bleach after testing a hidden seam for colorfastness.
Which stain remover is safe for polyester?
Use a pretreatment spray or dry-cleaning solvent for the spot step, applied from the wrong side. Save the all-fabric oxygen bleach for stubborn marks that remain after that.
Will a set-in polyester stain ever come out?
Sometimes not, especially once a stain has dried or been ironed in, since that is the hardest case. Treat it as early as you can, and see the set-in section for the stronger options and what's realistic.
Is vinegar safe on polyester?
Skip vinegar on polyester, since it can cause a color change and weaken acetate and triacetate. It can weaken acetate and triacetate and may cause a color change, so leave it out of your polyester routine.
