Although, you can easily wash winter clothes at home if you know the right method because if handled by an amateur, things may go wrong and you end up damaging your favorite woolens.
Nowadays, I see a number of mild liquid detergents Ezee, Safewash, etc. placed on the shelves of a super market close to my house. A few drops of such liquids are enough to get the job done.
Fill a half bucket with fresh running water. Do not fill it with warm water as it may lead to loosening of the fabric threads and even fading of the cloth's color.
Add Ezee or Safe wash or Genteel according to the number of clothes you are putting in. For half a bucket water, one lid of the bottle should be enough.
Soak the dirty winter clothes in that detergent mixture for 30 minutes.
Rinse them with running water thoroughly. A vigorous rinse might lead to tearing the fabric apart. So, be gentle in handling.
Rinse multiple times, as the water gets absorbed along with the detergent intensely in winter clothes.
Squeeze excess water gently.
Dry them in shade and iron the dry clothes by setting the iron at a low temperature.
Hence, it is not necessary to spend a lot of money on dry-cleaning of clothes like sweaters and jackets. One can go on washing them at home but not with detergents like surf excel and Ariel.
