Washing your new jeans in salt helps to set their dye, preventing them from fading. In the past, using salt to keep the color on your blue jeans was necessary because of a lack of quality laundry products for dark colors, and jeans makers then did not use dye as fade-resistant as that used today. Washing your new jeans in salt can still help to set the coloring on your jeans, preventing fading and running of the blue jean dye, which could stain other clothes in your washing machine.
How to Wash New Jeans in Salt
Things You'll Need
2 tbsp. salt
1 gallon water
Combine 2 tbsp. salt and 1 gallon cold water in a two-gallon bucket.
Completely submerge the new pair of blue jeans in the salt water.
Let the jeans soak in the salt water for 1 hour.
Remove the jeans from the soaking liquid and turn them inside out.
Wash the soaked blue jeans immediately on the cold wash cycle of your washing machine using your usual laundry detergent, and machine or line dry before wearing.
