Prep first
Before you start
- Act while the stain is fresh, since the longer grass sits, the harder it is to lift.
- Test your soap on a hidden spot before you treat the stain.
- Keep heat away from the grass until it is gone.
Grass on wood leaves a green mark that can soak past the finish, and the finish sets the limit on how much moisture gets in. Wax, oil, shellac or bare wood all respond differently, so identify the finish before you wet anything. A fresh mark on a sealed surface usually lifts after a couple of gentle rounds, while an older one may only lighten.
Getting grass stains out of wood starts with the finish, so test a hidden corner with a damp cotton cloth first. Hardwood floors and decks usually take a drop of mild dish soap in water, but waxed or unfinished wood may not. If the mark only lightens and goes no further, stop and ask a pro what the finish can take.

6 steps
Step by step
Step 1 of 6
Brush off the loose grass
Use a dry cloth or soft brush to lift off loose blades and bits of grass. Work from the edge of the stain toward the middle so the grass doesn't spread across the wood.
Step 2 of 6
Mix the mild soap solution
Stir a mild soap into lukewarm water until it is evenly mixed and the soap has dissolved. You only need enough solution to make a good layer of foam.
Step 3 of 6
Whip up a generous foam
Swish the solution with your hand or a whisk until it builds a thick layer of suds. You want the foam, not the liquid, to touch the stain.
Step 4 of 6
Dab the suds onto the stain
Dip a sponge into the suds and dab them onto the grass stain. Dabbing lifts the stain without spreading it, and it keeps the wood as dry as it can be.
Careful. Wood can take only a dry or slightly damp cloth, so squeeze the sponge until it is barely damp.
Step 5 of 6
Rinse with a barely damp sponge
Dampen a clean sponge with clear water and wipe over the spot to lift off the soap. Wring it out well before each pass so no liquid pools on the wood.
Step 6 of 6
Wipe the wood dry
Dry the spot right away with a clean, dry cloth. Wipe with the grain and press gently so the surface is left dry.

Pick a mild liquid soap with no added bleach. A plain, mild dish soap is a good fit for this method.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on wood furniture, 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
On a sealed surface, the green should lighten with each pass of suds and rinse, and the wood should look even once it's dry. If the spot stays put after a few gentle passes, the stain has likely moved deeper, so stop wiping and read the old-stain section.
What changes for yours
Adjust for your wood furniture
Waxed, oiled or unfinished wood
These finishes need the lightest touch, so use only the foam and wipe dry right away. Don't reach for a wood cabinet cleaner on them, even one labeled for wood.
If you can't tell which finish you have, don't guess. Stick to the dry brushing and the foam, and keep the sponge barely damp.
Sealed wood furniture
Sealed tables, chairs and cabinets follow the same steps, with the sponge kept barely damp throughout. Work on one small area at a time so the suds don't reach the rest of the piece.
Let the spot dry fully before you judge the result. A dry look is the only fair test of whether the grass has lifted.
Hardwood floors
Floors get the same gentle steps, but keep the sponge barely damp and skip ammonia and household dust treatments. Use only cleaners the finish maker recommends, since others can ruin the finish and void the warranty.
Water and pet stains are a different problem from grass, so the floor guide covers them in full. For the complete floor rules, see the Hardwood Floors guide.
Decks and wood fences
Outdoor wood like decks and fences is handled on its own guide, because it sits in weather and dirt all year. Try the gentle cleaning only on a small spot, and only where the wood is dry.
Rinse the spot fully so no soap film is left behind. For larger outdoor areas, see the Decks & Wood Fences guide.
Heavy or long-standing buildup
Old grass stains are harder to lift than fresh ones, so the gentle method above is the one to start with. Repeating the suds step is fine as long as the wood dries fully between passes.
If the grass has dried into the wood, brush off the crust with a dry brush first, then repeat the suds step with a barely damp sponge. Let the spot dry completely before you judge the result.
If it is still visible after one or two rounds, stop there. A faint mark is easier to live with than a damaged finish, so call a wood flooring professional for anything more.

Do home remedies work on grass on wood furniture?
Common household remedies for grass show up in plenty of guides, but most of them don't suit wood. Here is where each one stands for this stain.

What makes it worse
Mistakes to avoid
Don't use bleach as a first try
Chlorine bleach is a repair step for dark old moisture stains on wood, not a grass cleaner. For grass, the mild suds method is the right tool, so keep bleach out of the first attempt.
Don't put wax over a surface finish
Wax layered over a surface finish is hard to undo, and it won't remove the grass mark underneath. Clean with the mild soap method first, then decide what the finish actually needs.
Don't use a cabinet cleaner on bare or waxed wood
Wood cabinet cleaners aren't meant for waxed, oiled, shellacked or unfinished wood, and on those surfaces they can strip the protection that's already there. Check the finish before you reach for any spray.
Don't use ammonia or dust treatments on floors
Ammonia and household dust treatments are off the table on wood floors, even when a mark looks stubborn. Stick to the mild soap approach and rinse with a barely damp sponge instead.
When to call a professional
If the mark has soaked past the finish into bare wood, or repairing it means sanding and recoating, bring in a certified wood flooring professional for a floor or a furniture refinisher for a piece. In a home built before 1978, any repair that disturbs more than 6 square feet needs lead-safe certification, so ask about that before work starts. Tell them it's a grass stain and what the finish is, so they can match it.
Questions
Will a grass stain stay on wood forever?
Not always, but time works against you. The longer grass sits on wood, the harder it is to lift, so act while it is fresh. Gentle suds and a barely damp sponge give you the best chance before anything stronger is considered.
Can I sand a grass stain out of wood?
Sanding is not a first step, and it is best left to a wood flooring professional. Resanding, abrading and recoating all change the surface, so try the gentle method first.
Can I use a steam mop on a grass stain on a wood floor?
No. Wet mops and steam mops damage the finish and, over time, the wood, so a stain is never a reason to use one. Clean the spot with the suds method instead, and dry it with a cloth.
What if the stain is still there after one try?
Let the wood dry fully, then repeat the suds method once more. Stop after that, since more scrubbing mostly risks the finish without lifting much more. A stain that stays after that is usually one a wood flooring professional can address.
Can a grass mark leave a white ring on wood furniture?
It can, when moisture from the grass gets into the finish and leaves a pale haze as it dries. Very fine steel wool with a little wipe-on finish often clears that haze, since the finish is what got damaged. Try it in a hidden corner before you commit, and make sure the ring isn't just surface dust.
Can a dark grass mark on wood be bleached out?
Sometimes, but only as a repair after gentler methods have failed. Diluted chlorine bleach can lighten an old dark mark when you sponge it on around the spot, wait 5 to 10 minutes, and then apply it to the mark itself. Wipe it dry after each application and test a hidden area first, since bleach can change the wood's color.
How do I know whether my wood has a wax coating?
Dip a rag into mineral spirits and test it on a hidden corner. If the rag picks up yellow or brown, you're dealing with wax, and that changes which cleaner is safe to use.
