Draw out the oil; work in dish soap. Never the dryer or rubbing. A tough one on linen: expect more than one round.

01 The short answer
To get bike grease out of linen, work in this order: (1) draw out the oil; (2) work in dish soap. The key measure: cornstarch on it, 15–30 min, brush off. Wash as normal at the warmest temperature the care label allows.
This has a higher editorial difficulty rating. Consider professional cleaning rather than stronger or repeated home treatments.
02 Never do this
- The dryer before it is gone. Dryer heat locks in whatever is left. Air-dry and check first.
- Rubbing or scrubbing. It spreads the stain and grinds it deeper; blot instead.
- Hot water. Heat helps pigments bond to the fibres before you have lifted them.
03 Before you start
- Use white cloths or paper towels only: coloured ones can transfer their own dye into linen.
- Read the fibre and care labels, including lining and trims. Use only treatments permitted by both the item and product labels; a crossed-out triangle prohibits bleach.
- Pretest every permitted treatment on an inconspicuous area, including trims, and let it dry. Stop for colour transfer, lightening, rings, stiffness or distortion. A successful spot test does not guarantee the whole item is safe.
- The listed products are not permission to combine treatments. Use each only if the exact item and product labels permit it, including any change of product. Rinsing or blotting does not establish compatibility; ask the manufacturers or a professional if unsure.
04 The method
Draw out the oil
Cover the stain completely with cornstarch (or baking soda or talc) and leave it 15–30 minutes. Brush or vacuum it off, and repeat while the powder still comes up darker.
Why it works: Fine powder pulls fresh oil out of the linen by capillary action, like a wick. It is the gentlest way to remove the bulk of the oil.

Work in dish soap
Work a few drops of clear dish soap into both sides of the stain with your fingertips or a soft toothbrush. Leave it 5–10 minutes, then rinse with water as warm as the care label allows, up to 40 °C (104 °F).
Why it works: Dish soap surrounds the oil so water can carry it away; warm water helps fat dissolve.

Wash and check
Wash as normal at the warmest temperature the care label allows. Check the spot before it goes anywhere near a dryer; air-dry it if any trace remains, because heat sets what is left.
Why it works: A full wash removes the loosened stain and any product residue.

05 Dried, set, or back again?
- Old oil has partly oxidised and gone sticky; apply the degreasing step two or three times, and give powder an overnight stay where it is used.
Oil is often invisible on damp fabric and shows again once dry. Check in daylight after air-drying and repeat the degreasing step before any heat.
06 What bike grease is made of
- Oil and fat
- Pigment particles
The oily part of bike grease will not dissolve in water at all. It needs a surfactant such as dish soap, or a solvent, to break it up, and a dry powder can draw fresh oil out before you start.
Bike grease can contain pigment particles that do not dissolve readily in water. Many must be lifted with an appropriate cleaner rather than relying on bleach. Avoid grinding particles into the material; pigment chemistry and product formulas vary.
- Chain grease is heavy petroleum oil loaded with fine metal and carbon particles, so it is a grease stain and a pigment stain at once.
- WD-40 loosens old, dried chain grease because like dissolves like; dish soap then removes the WD-40.
07 The material: linen
Soaking is allowed, which gives enzymes and oxygen bleach time to work without scrubbing.
- Linen is a cellulose fibre, but dyes, finishes, construction and care instructions determine which treatments it can tolerate.
- Chlorine bleach weakens linen fibres faster than cotton; oxygen bleach is the safer whitener.
The linen file rates every common cleaner for it.
08 Next time
Use a trouser clip or roll your right trouser leg when cycling, and keep chains clean so there is less grease to pick up.
09 Questions
Can I use hot water on bike grease on linen?
No. Heat helps pigments bond to the fibres before you have lifted them. Keep to cold water until the stain is completely gone, then wash as warm as the care label allows (up to 40 °C (104 °F)).
Does vinegar help with bike grease on linen?
It is not needed for bike grease. Vinegar is a mild acid that helps with tannin and mineral residue; bike grease responds better to cornstarch and dish soap.
Can I use bleach on bike grease?
Not chlorine bleach on linen: it strips colour from dyed fabric.
Will bike grease come out of linen completely?
This has a higher editorial difficulty rating. Consider professional cleaning rather than stronger or repeated home treatments.
When should I call a professional?
Antique table linen, heirloom napkins and linen-silk blends.
What if it has already dried or been through the dryer?
Old oil has partly oxidised and gone sticky; apply the degreasing step two or three times, and give powder an overnight stay where it is used.
