Wash in room temperature water (30-40°C) to maintain the dark color of the jeans. This process is gentle; however, it brings out the least amount of contrast. Wash in warm water (60°C) for higher contrast. This is rougher on the jeans and can cause shrinkage.
Step 1 :
Turn your jeans inside out and wash with special denim detergent or washing powder without bleach.
Turn them back and hang to dry.
Hand washing is by far the best way to wash your jeans.
Step 1 :
Prepare a bucket of warm water. Add washing powder without bleach.
Step 2 :
Submerge your jeans in the water and gently massage all around. Repeat the step on both sides.
Step 3 :
Wash the detergent off. Turn them back and hang to dry.
This process is best suited for maintaining the dark color of the jeans. Remove the
surface dirt and spots by using a small brush. If the jeans develop a musty smell,
turn them inside out, spray them with starch and hang them out in direct sunlight.
Stretching and Shrinking
Stretching is inevitable after being worn. The degree of stretch varies upon usage and types of denim.
Shrinkage depends on the temperature of water and types of denim. Jeans will usually stretch out again after being worn over time.
Fill 1/4 of a bathtub with hot water but not boiling hot. Keep in mind that the hotter the water, the more chances of shrinkage and bleeding.
Button up your jeans and turn them inside out. Submerge in hot water and use a heavy object to weigh the whole jeans below the surface of the water. Soak for 1-2 hours then hang to dry.
If your jeans shrink too much, wear them and sit in a bathtub filled with warm water for about 45 minutes. This will stretch your jeans back to a comfortable size.
