Wash jeans in natural salt?

Why we wash new jeans using natural Salt in Japan. Washing your new jeans in natural salt helps to set their dye, preventing them from fading. In the past, using salt to keep the colour on your blue jeans was necessary because of a lack of quality laundry products for dark colours and jeans makers then did not use dye as fade-resistant as that used today.

Washing your new jeans in natural salt can still help to set the colouring in your jeans today, preventing fading and running of the blue jean dye, which could stain other clothes in your washing machine. The best natural salt for washing denim is Himalayan crystal salts.
