How to remove grass stains from cotton & linen
Grass stains are an inevitable part of outdoor life. Whether from travel, time in nature, or everyday wear, cotton and linen garments often come into contact with grass and soil. While these stains can appear stubborn, they are usually removable when treated correctly. The key is understanding how grass interacts with natural fibres and responding with care rather than force.
This guide outlines gentle, effective methods for removing grass stains from cotton and linen while preserving the integrity, colour, and longevity of the garment.
Why grass stains cling to cotton and linen
Grass stains are made up of chlorophyll, plant proteins, and natural dyes that bind easily to cellulose fibres. Cotton and linen are highly absorbent by nature, which allows pigment to travel deep into the fibre structure. Heat, friction, and time can cause these pigments to set, making removal more difficult.
Early intervention and low-impact treatment are more effective than harsh detergents or aggressive washing.
Before you start
Check the care label
Always begin by reading the garment’s care label. Pay close attention to recommended water temperatures and any warnings about colourfastness or agitation.
Act before washing
Avoid placing a grass-stained garment into the washing machine before treating the stain. Washing, particularly in warm or hot water, can lock the pigment into the fibres permanently.
What to avoid
Do not use chlorine bleach, strong solvents, or stiff brushes. Avoid hot water and tumble drying until the stain has been fully removed.
Step-by-step method for fresh stains
Step 1: Blot excess residue
If the stain is still green and damp, gently blot the area with a clean, dry cloth to lift any surface grass or moisture. Avoid rubbing, as this can push pigment deeper into the fibres.
Step 2: Rinse from the reverse side
Hold the stained area under cool running water, rinsing from the inside of the garment. This helps push the green pigment out of the fabric rather than further in.
Step 3: Apply mild detergent
Apply a small amount of mild liquid detergent directly onto the stain. Using your fingers, gently work the detergent into the fabric without scrubbing.
Step 4: Allow time to lift the stain
Leave the detergent on the stain for 10 to 15 minutes. This gives the detergent time to loosen the plant pigment.
Step 5: Rinse and assess
Rinse thoroughly with cool water and check the area in natural light. If the stain has lightened but is still visible, repeat the process before washing the garment.
Step 6: Wash only once the stain is gone
Once the stain is fully removed, wash the garment according to the care label and allow it to air dry.
Gentle stain removal methods for cotton and linen
Mild liquid detergent method
Apply a small amount of biodegradable liquid detergent directly to the stain. Gently massage into the fabric and allow it to sit for 20 minutes. Rinse well with cool water and assess before laundering.
White vinegar solution
Mix equal parts white vinegar and cool water. Dab the solution onto the stain using a clean cloth and allow it to sit for up to 30 minutes. Rinse thoroughly. Always test on an inconspicuous area first, especially on coloured garments.
Baking soda paste
For sturdy cotton or linen, mix baking soda with a small amount of water to form a soft paste. Apply to the stain and allow it to dry fully before rinsing. This method can help lift residual pigment without bleaching when used sparingly.
Rubbing alcohol use
Rubbing alcohol may be used cautiously on colourfast, durable cotton or linen. Apply with a cotton cloth and blot gently. Rinse immediately and avoid repeated use, as alcohol can dry fibres over time.
Washing after treatment
Water temperature
Wash treated garments in cool to lukewarm water only. Higher temperatures increase the risk of setting any remaining pigment.
Detergent choice
Choose a mild, low-residue detergent free from optical brighteners or harsh enzymes. These are better suited to natural fibres and reduce long-term wear.
Air drying and reassessment
Always air dry after stain treatment. Heat from a dryer can permanently set faint remnants of grass pigment that are not visible while wet.
Fibre-specific considerations
White cotton and linen
White natural fibres can tolerate repeated gentle treatments better than bleaching. Allow time between attempts and reassess in natural light before re-treating.
Coloured cotton and linen
Coloured garments require additional care. Limit soaking times and avoid acidic treatments unless tested. Multiple light applications are safer than one intensive attempt.
Common mistakes to avoid
Using hot water before the stain is removed, scrubbing aggressively, applying chlorine bleach, and tumble drying prematurely are the most common causes of permanent grass stains.
When to pause and seek professional care
If the stain remains after two or three careful treatments, or if the garment shows changes in colour, texture, or drape, it may be time to stop. Professional cleaners experienced with natural fibres can assess whether further treatment is possible without compromising the garment.
Preserving the integrity of the piece is often more important than complete stain removal.
Preventing future grass stains
Rinse garments promptly after outdoor wear, especially before stains dry. Wearing natural fibres in looser fits can reduce friction and pigment transfer. Washing less frequently and spot-cleaning when needed also helps extend garment life.
Afar care philosophy
At Afar, care is considered an extension of design. Thoughtful laundering, gentle stain removal, and patience with natural fibres help garments age beautifully over time. Grass stains are part of a life well worn. How they are treated determines how long the garment continues its journey.
