Prep first
Before you start
- Fix whatever keeps the garment damp first, like a leaking shelf or a closet with no airflow.
- Put on gloves, goggles without vents and an N-95 respirator before you touch it.
- Take it outside before you shake it, so loose spores don't drift through the house.
- Keep it away from clean clothes until it's fully dry.
Mold on dry clean only delicates leaves a mark, but the damage underneath is often the bigger concern. Mold can't grow without water or moisture, and a patch that has only just appeared usually lifts more readily than one that has sat for weeks. Because the label rules out washing at home, that label also sets the limit on what you can do yourself.
Getting mold out of dry clean only clothes is often a job for a professional when the mark is deep or old. Hang the garment outdoors in the shade, away from direct sun and away from other clothes, to start on a mildew smell in delicate clothes. Only reach for a delicate laundry detergent if the care label allows any liquid at all.

6 steps
Step by step
Step 1 of 6
Read the care label first
Check the tag for the words dry clean only before anything touches the stain. If it says that, the home steps are limited to shaking and drying, and the garment goes to a cleaner. If the tag is missing or unreadable, don't guess; treat the garment as dry clean only.
Careful. Do not use any product or procedure prohibited by the care label.
Step 2 of 6
Shake loose mold off outdoors
Take the garment outside and shake it gently so loose mold falls away from the fabric, not into your home. Keep the movement light, since rough handling can spread spores and push the growth deeper into the weave.
Careful. Rubbing or brushing the stain can damage the fibers, which mildew has already weakened.
Step 3 of 624 to 48 hours
Dry the garment all the way through
Hang it in a room with good airflow, away from other clothes, until it is dry all the way through, including the seams and lining. Wet areas dried within 24 to 48 hours usually won't grow mold, so don't leave it balled up or bagged while it's damp.
Tip. Seams and linings stay damp longer than the outer fabric, so check them by feel before you put the garment away.
Step 4 of 6
Test before any cleaner touches it
Before any cleaner goes on the stain, try it on a hidden seam or inside hem and let it dry. Look for color change, rough patches or thin spots before you go any further.
Careful. Pretest each cleaning agent on an inconspicuous area first, because a color change can't be undone.
Step 5 of 6
Take it to a dry cleaner
Bring the garment to a dry cleaner and say the stain is mold or mildew, not an ordinary spot. Ask them to check the fabric before they treat it, because a cleaner can judge what the garment can take.
Tip. Bring it in dry and loosely wrapped, so it doesn't pick up damp on the way.
Step 6 of 6
Look at it in daylight
Once it's back, check the garment in daylight before you hang it up. If a mark or musty smell is still there, don't store it in a closed bag or closet, because trapped moisture is what lets mold return.

Best products for mold on delicates & lace
For storage, choose a breathable cotton garment bag over plastic, since trapped moisture is what lets mold return.
Woolite Delicates
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on delicates & lace, 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.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
The mark should look lighter, and the garment should smell clean once it's fully dry and back from the cleaner. If the spot is still dark, or the fabric feels stiff, thin or rough, stop and let the cleaner check it, since the fibers may be damaged.
What changes for yours
Adjust for your delicates & lace
Musty smell
A musty smell on a dry clean only garment usually means it still holds some moisture or mold spores, even if the spot looks clean. Let it dry fully and get it out of the closet before deciding anything else.
Don't cover the smell with perfume or fabric spray, since that hides the problem and does nothing to the source. Tell the dry cleaner about the smell as well as the stain, so they can check for mold rather than just pressing the garment.
Mildew smell
A mildew smell in delicate clothes comes from damp that has worked into the fibers, so airing and full drying matter more than any cleaner. Give the garment time to air out in a room with good airflow, away from other clothes.
Because mildew weakens fibers, don't soak or scrub the garment to chase the smell. If the smell persists after it's dry, let a cleaner handle it rather than trying another round at home.
Heavy or long-standing buildup
Old mildew stains on fabric often mean the fibers are already damaged, and that changes what's realistic. Mildew weakens fibers, and fabrics badly damaged by mildew may be impossible to clean. So on an old stain, the goal is usually to stop further damage rather than to erase every mark.
Old stains are harder to remove than fresh ones, and some won't come out at all. If the mark is still there after the garment is fully dry, stop home attempts and hand it to the cleaner as it is.
If the mark survives the cleaner, it may be permanent, because part of the discoloration is damage to the fiber itself. Ask what they could and couldn't remove, so you know what to expect before deciding what to do with the garment.

Do home remedies work on mold on delicates & lace?
Most home remedies for mold and mildew are built for hard surfaces or washable fabric, so they don't carry over to a dry clean only garment. Here is how each common option fares for this stain on this kind of fabric.

What makes it worse
Mistakes to avoid
Don't mix bleach with other cleaners
Never mix chlorine bleach with ammonia or any cleaner that contains it, because toxic fumes could be produced. Never combine chlorine bleach with lemon juice or vinegar either. Chlorine isn't a safe home step on dry clean only fabric unless the label allows it.
Don't iron velvet
Heat and pressure flatten the nap on velvet, so keep the iron away from it while it dries. A flattened nap doesn't come back with a cleaner's pressing alone.
Don't use acetone on acetate
Do not use acetone on fabrics that contain acetate, and that includes many nail polish removers. Check the fabric content on the care label before you reach for any solvent.
Don't mix your own cleaner
Homemade mixes of household cleaners are a gamble on delicate fabric, and a garment that can't be washed can't be rescued by a kitchen experiment. Let the cleaner handle anything stronger than the steps here.
When to call a professional
When the label says dry clean only, a cleaner is the right route, and it's the only route that can handle the stain safely. For a valuable or vintage piece, look for a specialist in delicate and historical garments rather than a general drop-off service.
Questions
Can I wash mold out of dry clean only clothes at home?
Not safely. A dry clean only label rules out washing, soaking and bleaching, so the garment should go to a cleaner who can treat mold. Drying and shaking it out at home are the safe steps before that visit.
Can the mold stain come out completely?
Sometimes, but not always. The mark is partly damage to the fibers, so the older the stain and the more the fabric has been hit, the less likely it is to come out fully.
How long can a damp garment sit before mold starts?
Don't wait long. Get it dry within 24 to 48 hours, since that's the window where damp fabric usually stays mold-free.
Why does mold keep coming back after cleaning?
Mold needs moisture to grow, so it returns when the fabric stays damp. Make sure the garment is fully dry and stored where air can move around it.
Can I iron the mark out?
No. Heat and pressure flatten the nap on velvet, and the iron does nothing to the damage underneath the stain. Hold off on the iron until the garment is dry, and let the cleaner decide whether any pressing is safe.
What if the cleaner says the stain won't come out?
Then the damage is likely in the fiber itself, and no home method will change that. Ask the cleaner what they could and couldn't remove, and decide what to do with the garment from there.
