The most effective method for removing stubborn grease stains from linen is to vacuum the surface, followed by pretreating with a grease-cutting detergent.

Baking the grease with baking soda: Do not rub the grease stain.

Generously sprinkle the stain with baking soda or cornstarch. Let it sit for 15–20 minutes until the powder has absorbed the excess grease. Then gently brush or shake it off.

Pretreating with a grease-cutting detergent: Let it sit for 10–15 minutes.

Place a drop of colorless liquid detergent directly onto the stain. Gently work the detergent into the linen fibers with your fingers or a soft toothbrush and let it soak in.

Wash at the highest possible temperature:
Wash the garment at the maximum temperature indicated on the care label (usually 30–40°C) using a standard liquid detergent.

Check and air dry: Do not use heat until the stain is gone.

Check the area after washing. Do not tumble dry or iron the garment until the stain is completely removed, as heat will permanently set the grease into the linen fibers. If stains remain, repeat the process.

For old or dried-in stains: Rub in some turpentine substitute before treating it with dish soap, or spray the garment with an ammonia solution before placing it in the washing machine
