Removing stains from a cashmere sweater requires delicacy to avoid damage to the delicate fabric. Here are some tips on how to deal with different types of stains:

1. Liquid Stains (e.g. coffee, wine):

Gently absorb excess liquid with a clean, absorbent cloth, without rubbing.

Gently blot the area with a damp cloth soaked in cool water and a mild detergent, such as mild soap.

Avoid using hot water or vigorous scrubbing, as it may damage the cashmere fibers.

Gently pat dry with another clean, dry cloth.

2. Oily Stains (e.g. oil, makeup):

If possible, apply a little talc or cornstarch to the stain and let it sit to absorb the oil.

After a few minutes, remove the talcum powder with a soft brush or clean cloth.

Gently blot the area with a damp cloth and mild detergent.

Repeat the process until the stain is completely removed.

3. Food Stains (e.g. sauce, chocolate):

Gently scrape away any solid residue with the back of a teaspoon or blunt knife.

Blot the area with a cloth soaked in cold water and a mild detergent.

If the stain persists, apply a small amount of white vinegar diluted in water (1 part vinegar to 2 parts water) and dab gently.

Gently pat dry with a clean, dry cloth.

4. Ink Stains:

Treat the ink stain immediately with a little warm milk and a clean cloth. Blot gently until the stain begins to lift.

Then, dab with a damp cloth and mild detergent.

Repeat the process until the stain is completely removed.

General Advice

Avoid using bleach or other harsh detergents, which could damage the cashmere fibers.

Do not rub stains vigorously, as this may cause damage to the fabric.

If you are unsure about how to treat a specific stain, consult a dry cleaning professional.

Always remember to test any detergent or cleaning method on a small, hidden area of the shirt before applying it to the entire stain, to ensure it doesn't cause damage or discoloration.
