How to Wash and Care for Denim So It Actually Lasts
Denim is built to age, but only if you treat it right. Here's exactly how to wash, dry, and maintain your jeans so they stay dark, fit well, and last for years.
5 min read · IrisThe biggest mistake people make with denim is washing it too often and too hot. Your jeans don't need a full wash after every wear—in fact, they prefer restraint. Denim is a fabric that develops character through selective care, fading in patterns unique to how you move and wear it. This guide walks you through the exact process to keep your denim dark, comfortable, and structurally sound.
Whether you own a single pair of raw selvedge or a rotation of vintage-inspired styles, the fundamentals are the same: cold water, minimal agitation, and air drying. These three principles will extend the life of your jeans by years while preserving the indigo dye that makes denim worth wearing in the first place.

Step one · 1 minute
Spot-clean between washes
Before you wash your jeans, spot-clean any visible stains with a damp cloth and mild soap. For scuffs or minor marks, rub gently with a soft brush or old toothbrush. This approach lets you extend the time between full washes—aim for every 5–10 wears for regular jeans, or even longer for raw denim. If your jeans smell fresh, they don't need washing yet; air them out overnight instead.
Keep a soft brush or microfiber cloth handy for quick spot treatments.
Step two · 2 minutes
Turn jeans inside out and prepare for washing
Always flip your jeans inside out before washing. This protects the visible indigo dye on the outside from fading and friction. Close all zippers and button the waistband to prevent snagging. If you have raw or selvedge denim, this step is non-negotiable. For heavily worn areas like the thighs or knees, you can also tie a loose knot in the fabric to reduce agitation in those spots.
Zip and button your jeans every time—it takes five seconds and prevents damage to other garments.
Step three · 3 minutes
Wash in cold water on a gentle cycle
Use cold water only—hot water opens the fiber and releases dye. Set your machine to a delicate or gentle cycle, or hand-wash if you're caring for premium denim. Use a small amount of mild detergent; you need far less than you think, and excess soap leaves residue that dulls the fabric. If washing with other items, stick to similar colors and weights. Never use bleach or fabric softener, both of which damage denim's structure and finish.
If hand-washing, soak for 20–30 minutes in cold water with detergent, then gently agitate and rinse thoroughly.
Step four · 1 minute
Rinse thoroughly until water runs clear
After the wash cycle, rinse your jeans multiple times in cold water until no soap residue remains. You'll see the water gradually clear—that's the excess detergent leaving the fabric. Proper rinsing prevents soap buildup, which can make denim stiff and dull. If hand-washing, change the water and rinse at least three times. This step matters more than most people realize.
Use the rinse cycle on your machine, or manually rinse under cold running water.

Air-dry flat or on a hanger—never use heat
Skip the dryer entirely. Heat shrinks denim, fades color, and weakens fibers. Instead, gently squeeze out excess water (don't wring), then lay your jeans flat on a clean surface or hang them by the waistband on a sturdy hanger in a well-ventilated area. If laying flat, smooth out wrinkles with your hands. Drying takes 24–48 hours depending on humidity and thickness. Your jeans will feel slightly stiff when dry—this is normal and softens with wear.
Hang jeans in front of a window or fan to speed drying, but avoid direct sunlight, which can cause uneven fading.

Store properly to maintain shape and color
Fold your jeans along the inseam and stack them in a drawer, or hang them on a sturdy hanger if you prefer. Keep them away from direct sunlight and heat sources, which fade indigo over time. If storing long-term, ensure the space is dry and cool. Rotate between pairs when possible—this gives denim time to rest and recover its shape between wears. Never store damp jeans; always ensure they're completely dry first.
If your jeans develop a crease you don't want, hang them inside-out for a few hours to relax the fabric.
How to know your denim care routine is working
Well-cared-for denim shows gradual, intentional fading in high-wear areas—the thighs, knees, and back pockets develop a unique patina that reflects your movement. The fabric remains soft but structured, the color stays rich (not pale or uneven), and the fit holds its shape wash after wash. If your jeans feel stiff, look dull, or shrink unpredictably, you're likely washing too hot or too often.
Questions at the mirror.
How often should I actually wash my jeans?
For regular-wear jeans, every 5–10 wears is ideal. For raw or selvedge denim, stretch it to 10–20 wears if possible. If your jeans smell fresh and have no visible stains, they don't need washing—air them out instead. Overwashing is the enemy of longevity and color.
Can I wash jeans with other clothes?
Yes, but only with similar colors and weights. Wash dark denim with other darks, and light denim with other lights. Avoid washing jeans with delicate fabrics, towels, or anything with loose buttons or zippers that could snag. Denim is sturdy, but it's also a dye-shedder, especially when new.
What if my jeans have a hole or tear?
Wash as normal, but be gentle during the rinse cycle to avoid enlarging the damage. For small holes, consider patching before washing to prevent fraying. For intentional distressing, wash inside-out to preserve the effect.
Is it okay to use fabric softener on denim?
No. Fabric softener coats the fibers and dulls the fabric's natural texture and appearance. It also reduces the lifespan of denim. Stick to mild detergent and cold water—that's all you need.
My jeans smell like mildew. What do I do?
This means they were stored damp or in a humid environment. Wash immediately in cold water, then air-dry completely in a well-ventilated space or in sunlight. To prevent this, always ensure jeans are fully dry before storing, and avoid sealed plastic bags.
