Caring for Denim
Denim is meant to age — fade, crease, whisker. Care here is minimal cleaning, maximum protection. Hit them with a water repellent before you wear them, brush off surface dirt, and let the patina build. Aggressive cleaning erases the character you actually want.
Overview
How often
Dry brush every few wears and spot clean marks as they happen; a fuller clean roughly every 20 wears. Protect when new, then every 3–4 weeks of regular wear (sooner when water stops beading) if you want to slow the fade.

Step by step
Step 1: Spot clean only
Never deep-soak. Cold water + microfiber on actual marks; leave the rest of the upper alone.
Step 2: Dry brush only between wears
Lifts surface dust without disturbing the indigo.
Step 3: Accept fade
The white-warp/blue-weft structure of denim means fade reveals the lighter cotton beneath. This is the look — don't fight it.
Step 4: Severe fade (rare)
Fade can't be reversed at home without risking uneven dye. If the toe box fades badly, a professional restorer can re-dye it. Most people never need this.
Step 5: Never machine wash
Indigo bleeds aggressively and the construction adhesives can fail.
Step 6: Protect when new
A PFAS-free protector like Crep Protect or Jason Markk Repel seals the indigo against rain and spills while still letting the natural fade develop. Re-apply every 3–4 weeks of regular wear (sooner when water stops beading) to slow the fade, or skip re-treating if you want it to age faster.
What to avoid
- Machine washing or soaking — indigo bleeds and glue can fail
- Hot water or heat to dry
- Scrubbing the whole upper — it erases the fade
- Storing against light leather — indigo transfers
By material
The routine above, adjusted for each material it covers.
Denim
Indigo denim (AJ4 Levi's Indigo, AJ1 23/501) follows the classic deep-blue-to-faded arc. White denim (AJ4 Levi's White Denim) is the highest-maintenance — stains set permanently, so protect it when new. Black denim (AJ4 Levi's Black Denim) fades to gray; protector slows this slightly.
Between wears
- Climate. Cool, dark, dry — same as leather, but it matters more. UV bleaches denim unevenly.
- Color transfer. Don't store with leather pairs — indigo can transfer to lighter leather surfaces in close contact.
- Shape. Stuff with paper to maintain shape during long-term storage.

Cleaning Canvas
The forgiving upper. Canvas — Chucks, Vans, canvas Jordans — handles direct cleaning and firm brushing. Skip the washing machine and bleach (it weakens fibers and yellows whites), and dry out of direct sun.

Cleaning Mesh & Knit
Flyknit, Primeknit, Roshe-style mesh — engineered for breathability, which means they soak up cleaning solutions and trap stains deep in the weave. Brush dry first, work the cleaner in lightly, and don't let water sit. Patience pays off here.
