If you want your Cashmere pullover to keep warm and soft, please follow these instructions:
Put your pullover to soak in lukewarm water and use just a little bit of detergent or shampoo. In case the pullover has stripes or bright colours, add a little bit of white vinegar.
Leave your pullover to soak for a short time, 10-15 minutes maximum.
Never rub it. Always handle with care.
Patiently rinse your pullover with a lot of lukewarm water and more than once until water runs clear.
Never wring. Eliminate water from your garment pressing it gently.
Wrap it in a towel to eliminate excess water.
Spread out your garment on a horizontal surface. Do not expose your garment to direct sunlight. Dry at room temperature and never put it on a radiator.
Iron with powerful steam jet. Never press with iron.
A little suggestion: wash your Cashmere garment often, since in this way fibres will find new vigour and your garment will always look as new.
