Prep first
Before you start
- Shake and tape off the pollen before anything wet touches it.
- Check the cleaning code on the tag.
- Blot any wet spot with a clean, absorbent cloth.
- Use only the cleaner your code allows, and nothing stronger.
Algae and moss on a fabric chair leave a dark, pigmented mark that settles into the weave, and rubbing it only pushes it deeper. The cleaning code on the tag decides what you can use: a W-coded seat can take water-based foam, while an S-coded one needs a water-free solvent. A fresh spot usually lifts with careful blotting, but an old one that has dried into the fibers may only fade.
A portable upholstery spot cleaner can lift a fresh mark from a fabric seat without soaking it. Work from the outer edge toward the middle so the stain doesn't spread, and keep a white cotton cloth under the spot to catch what lifts. If a lily pollen stain on a white chair won't budge after a few tries, stop and call a pro rather than scrubbing harder.

6 steps
Step by step
Step 1 of 6
Check the cleaning code
Find the cleaning code on the tag. W means water-based cleaners, S means water-free solvent only, WS means either, and X means no liquid cleaner at all.
If the code is X, do not use any foam or liquid cleaner. Vacuum or brush the spot lightly and stop there.
Step 2 of 6
Lift off the loose pollen
Shake the chair gently and tape off as much pollen as the tape will take, pressing the tape lightly. Use only the blunt edge of a table knife or a spatula to lift any loose solids, and don't scrape the stain itself.
Step 3 of 6
Blot any wet residue
If there is any wet residue, blot it with a clean, absorbent cloth, barely touching the fabric and pressing lightly. Blotting lifts the stain, while rubbing pushes it deeper into the weave.
Step 4 of 6
Pre-test on a hidden spot
Test your cleaner on a hidden area of the chair before you use it on the pollen. Stop if the cleaner transfers color to the cloth or changes the surface.
Step 5 of 6
Clean according to your code
Use only the cleaner your code allows. On W fabric, whip a water-based upholstery shampoo or mild detergent into foam and use only the foam; on S fabric, use a mild water-free dry-cleaning solvent; on WS fabric, either one works. Work from the outside of the spot toward the center, moving to a clean part of the cloth as it picks up the pollen.
Tip. Keep dry-cleaning solvent away from open flames, pilot lights and sparks, and work in a well-ventilated room.
Careful. Water on S-coded fabric, or solvent on W-coded fabric, can leave a permanent mark.
Step 6 of 6
Remove cleaner and dry fast
Once the stain is gone, blot out every trace of cleaner with a clean, barely damp cloth. Speed drying with a fan or a hair dryer set on cool so the spot dries evenly.
Tip. Too much cleaner leaves a residue that streaks and attracts dirt.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on chairs & upholstery, 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.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
A healthy result shows the dark tint coming off onto your cloth with each blot, and the spot getting paler as you work its edge. Let the fabric dry completely before you judge, because damp fabric always looks darker than it will. If a faint mark survives once the cloth comes up clean, it has likely set, so switch to the dried-stain steps.
What changes for yours
Adjust for your chairs & upholstery
Chairs with a W code
On a W-coded chair, the foam from a water-based upholstery shampoo or mild detergent does all the work. Whip the cleaner into foam and dab only the foam onto the pollen, never a wet pool, and keep it to the spot.
Let the fabric dry fully before you judge the result, then check it in good light.
Chairs with an S code
On an S-coded chair, the mild water-free dry-cleaning solvent is the only cleaner to use. Apply a small amount to a clean cloth rather than to the chair itself, and lift the pollen gently, stopping once the cloth comes away clean.
Let the solvent evaporate fully, then check the spot in good light before deciding whether a second pass is needed.
Chairs with a WS code
A WS-coded chair can take either cleaner, so pick one and stick with it on the same spot. Start with the water-based foam, applied only as foam and never as a wet pool. If the foam doesn't lift the pollen, switch to the dry-cleaning solvent on a clean cloth in a well-ventilated room.
Don't mix the two on the same spot, and let each one dry before you try the other.
Wooden chair frames and arms
If pollen has landed on a wooden frame or arm, the upholstery steps are for fabric, not for the finish. Brush the loose pollen off the wood first, and keep any cleaner away from the bare wood.
For the finish itself, the Wood Furniture guide covers the right cleaners and how to protect the wood. Follow that guide for the frame, and come back here only for the fabric.
Leather chairs
Leather doesn't take the fabric cleaners listed above, and rubbing alcohol is unsafe on it. Brush off the dry pollen first, and don't rub it in.
For the cleaner and the method for leather, the Leather guide is the right place to go.
Heavy or long-standing buildup
If the pollen has been sitting on the chair for days, it can settle into the fibers and become harder to lift. Start by brushing and taping off as much as you can, then repeat the cleaner your code allows on the same spot.
Let the spot dry completely before you judge it, because a damp spot always looks worse than it will be. Repeat the same light blotting with a fresh part of the cloth each time.
Keep the fan or hair dryer on cool, because heat can set the stain. If the pollen is still there after a few rounds, the stain may not come out fully, and a professional upholstery cleaner is the next step.

Do home remedies work on algae on chairs & upholstery?
Plenty of home remedies float around for pollen, but most of them don't suit a fabric chair. Only a few common picks suit a fabric chair, so check the cleaning code before you use any of them.

What makes it worse
Mistakes to avoid
Don't rub the pollen in
Pollen is a dry powder that spreads and sinks into the weave when you rub it. Shake it off and tape it up first, and blot any wet spot instead of working it in.
Don't skip the pretest
A cleaner that looks fine on the surface can bleed color or change the fabric under the spot. Test on a hidden area and let it dry before you work on the visible pollen.
Don't scrub the mark into the weave
The dark pigment sits inside the fibers, so a stiff brush or a rough cloth pushes it deeper instead of lifting it. Blot with a clean white cloth and move to fresh cloth as it picks up color. Scrubbing also roughens the pile, which can leave a mark that looks worse than the original stain.
Don't leave a damp cushion to sit
Algae grows where surfaces stay damp, so a seat that dries slowly invites the spot to return. Once you've blotted, speed drying with a fan or a hair dryer on cool. Get the spot fully dry the same day you clean it.
Don't bring a heat gun or iron near it
Heat can set the stain in place, so a hot tool can lock in the mark you're trying to lift. Stick to cool air for drying, and keep any hair dryer on its cool setting.
When to call a professional
Bring in a professional for an S-coded chair, since the guidance for that fabric is professional cleaning only, and for any large or unusual stain. If a pre-test shows dye moving or the fabric shrinking, stop and hand the chair over rather than pushing on. Tell them it was algae or moss, how long it sat, and which cleaners were already used.
Questions
Can lily pollen stain chair fabric permanently?
It can if it's rubbed in, left to set, or dried with heat. Shake and tape the pollen off right away, then clean with the cleaner your code allows.
What if the pollen is on a white chair?
Use the same steps, since a white fabric shows a faint mark more easily. Check the result in good light, and blot the spot dry so no ring forms.
Should I use a wet cloth to pick up pollen?
No. Wet pollen spreads and sinks into the weave, so shake and tape it off first. Only after the dry pollen is gone should you blot any wet residue.
How long should I wait before sitting on the chair again?
Wait until the fabric is fully dry, which you can check by touch and in good light. Don't sit on it while it's still damp from the cleaner.
Can I use a dryer or heat to speed up drying?
Use a fan or a hair dryer on cool, not hot. Heat can set the stain, so keep heat off until the spot is clean.
What if the pollen is still there after cleaning?
Repeat the cleaner your code allows on the same spot, with light blotting and a fresh part of the cloth each time. If it still shows after a few rounds, a professional upholstery cleaner is the next step.
What if I can't find the cleaning code?
Don't guess, since a wrong cleaner can wreck the fabric. Keep the spot dry, blot off anything wet, and have a professional upholstery cleaner identify the fabric before anything touches it.
Can I take the seat cover off and wash it?
Usually not. The guidance is to avoid removing cushion covers for laundering or dry cleaning, since a washed cover can shrink or fade, so treat the mark where it sits.
Can a steam cleaner lift algae from a chair?
Not on a stain. Steam is off the table for W and WS fabric, and its heat can set the mark. Stick to the cool, low-moisture steps, and if the stain is large, a pro can handle it.
Why is there a ring after I cleaned it?
A ring usually means too much liquid reached one area and it dried slowly. Keep your cleaner light next time, and rinse out any leftover soap. Speeding up drying with cool air can help prevent the edge from forming.
