If you want your jeans to look their best and last for many years, this is how to care for them:
Wash jeans for the first time after 4 months.
Hand wash jeans. Machine wash makes them age much faster.
Hang dry jeans. Never use a dry tumbler. Tumblers make them shrink and adds unnecessary wear.
Put jeans in the freezer to refresh them. (This works with smelly shoes and gym clothes as well.)
Let jeans lay in i pile or hang them. Folding creates unnatural patterns.
Use only water on jeans stains. Rub the stain with a towel. Using soap creates bleach stains.
No rocket science. :-)
