How to Wash Dark Jeans: Inside Out, Rare, Cold
Indigo sits on the yarn, not in it. Every wash is a fade. Cold, inside out, infrequent. The dryer is a stonewash you did not ask for.

Indigo wants to leave
Vat dye on denim crocks onto sofas and into wash water. That is the point of raw denim and the enemy of a $120 black jean you wanted to stay black. Inside out reduces abrasion on the face. Cold slows the dye. The rest is frequency.
Rare is a range, not a religion
Office darks: every few weeks if they are not sweaty. Cycling commuter: wash. Crotch blowouts come from wear, not from washing too often. Airing overnight on a hanger does more between washes than a cedar block in the wardrobe.
Fading control in general is its own guide; jeans are the loudest case.
Dry, fold, and the dryer
Hang from the hem or fold over a bar so the knees do not hook. A dryer fades, shrinks the cotton, and sets a crease you will wear as a white line. File-fold once dry. Spot oil with dish soap before the whole wash.
Questions, answered
- Should I soak new jeans in vinegar and salt?
- A cold vinegar rinse can set a little loose dye. Salt is a weaker folk version. Neither replaces cold, inside-out, rare washes.
- Can I wash jeans with towels?
- Towels sandpaper them. Wash denim with denim or alone.
- Is a denim-specific detergent worth $18?
- A mild liquid without optical brighteners is the actual requirement. The branded bottle is optional.
