The honest answer is that jeans don't need washing on a schedule. They need washing when they need it. That sounds like a dodge, so here is what "when they need it" actually means.

Wash jeans when one of these is true

• They smell. Not "smell like denim." Smell like you.
• They're visibly dirty or stained. A stain left alone for weeks is harder to remove than one dealt with that day.
• They've lost their shape. Baggy knees and a waistband that's grown an inch are signs the fibers have stretched out. Washing and drying helps cotton pull back.
• You've been sweating in them. Sweat and body oils break down fibers over time and attract more dirt.

For most people wearing everyday jeans to an office or around town, that works out to roughly every five to ten wears. If you work outdoors, do physical labor, or sit on public transit in summer, it'll be sooner. That's fine. Jeans were invented as workwear and have survived a great deal worse than a washing machine.

Why the "never wash your jeans" advice exists

Every wash removes a little dye and a little fiber. Indigo, the dye in most blue denim, sits mostly on the surface of the cotton rather than soaking through it, which is why jeans fade where they rub. Washing less often means slower, more even fading, and a pair that lasts longer overall.

That's a real reason. It's also a reason about appearance and lifespan, not cleanliness. Washing less is a trade-off, not a rule.

Stretch denim is different

Most jeans sold now contain some elastane (Spandex, Lycra). Stretch denim relaxes as you wear it, and it recovers its shape through washing and drying. Wear stretch jeans too long between washes and they bag out at the knees and seat. Wash them more often than rigid denim, in cold water, and keep them out of high heat, which damages elastane permanently.

Raw denim is also different

Raw (unwashed) denim hasn't been pre-washed at the factory. People who buy it usually want high-contrast fades that match how they move, so they wear it for months before the first wash. If that's you, you already know this and have opinions. When you do wash raw denim, soak it inside out in cold water with a little mild detergent, don't agitate it, and hang it to dry. Expect some shrinkage if it isn't pre-shrunk (sanforized). The tag will usually tell you.

About freezing your jeans

Putting jeans in the freezer is popular advice for "cleaning" them without washing. Freezing doesn't kill most of the bacteria responsible for odor. It slows them down, and they recover as the jeans warm up. What freezing does do is make your jeans cold. If they smell, wash them.

Between washes

• Air them out. Hang jeans somewhere with airflow overnight instead of leaving them folded in a heap.
• Spot clean. Small marks can often be dealt with using cold water and a drop of mild detergent on a cloth. Dab. Don't scrub.
• Rotate. Two pairs worn alternately last longer than one pair worn every day.

How to wash them when you do

1. Empty the pockets. All of them. Including the tiny one.
2. Button the button and zip the zipper, so the zipper teeth don't chew other things in the load.
3. Turn them inside out. This protects the outside color from friction.
4. Use cold water and a mild detergent, preferably one designed for darks if they're dark.
5. Wash with similar colors. New dark denim can bleed for the first few washes.
6. Use a gentle or normal cycle, not heavy duty.
7. Hang to dry, or tumble on low and take them out while slightly damp. There's more on this in how to dry jeans without shrinking them.

Or put them in a box and send them to me. I read the label, I follow it, and I don't have opinions about your fades unless you ask.

In the United States, the Federal Trade Commission's Care Labeling Rule requires most clothing to carry care instructions. Manufacturers only have to give you one method that's safe for the garment, and warn you about anything that would damage it. So the label isn't a list of every option. It's the one route the manufacturer is willing to stand behind.

Care symbols come in five families. Learn the five shapes and the rest is modifiers.

1. The tub: washing

A bucket with wavy water at the top means the item can be washed in water.

• Dots inside the tub are the maximum water temperature. One dot is cold, about 30°C or 85°F. Two dots is warm, about 40°C or 105°F. Three dots is hot, about 50°C or 120°F. Four dots is 60°C or 140°F. Some labels print the number instead.
• No line under the tub means a normal cycle.
• One line under the tub means permanent press: a gentler cycle with a cool-down, which reduces wrinkling in synthetics.
• Two lines under the tub means delicate or gentle: low agitation, slow spin.
• A hand in the tub means hand wash only.
• An X through the tub means do not wash in water at all. Believe it.

2. The triangle: bleach

• An empty triangle means any bleach is fine when needed.
• A triangle with two diagonal lines means non-chlorine (oxygen) bleach only.
• A solid or crossed-out triangle means no bleach of any kind.

Chlorine bleach on colored pants almost always ends badly. If you're not sure, don't.

3. The square: drying

The square is drying. A circle inside the square means tumble dry in a machine.

• Dots in the circle are heat. One dot is low, two is medium, three is high.
• A filled-in circle means tumble with no heat, air only.
• Lines under the square work the same as under the tub: one for permanent press, two for delicate.
• An X through the tumble symbol means keep it out of the dryer.

A square without a circle means dry it naturally:

• A curved line at the top means line dry. Hang it.
• Three vertical lines means drip dry: hang it soaking wet, without wringing.
• One horizontal line means dry flat. Usually knits, which stretch if hung.
• Two diagonal lines in the corner means dry in the shade, out of direct sun. Common on dark and bright colors.

4. The iron: ironing

• One dot is low, around 110°C or 230°F. Synthetics like acrylic and nylon.
• Two dots is medium, around 150°C or 300°F. Wool, silk, polyester.
• Three dots is high, around 200°C or 390°F. Cotton and linen.
• Lines crossed out below the iron means no steam.
• An X through the iron means do not iron. The fabric will melt, shine or pucker.

5. The circle: professional cleaning

A plain circle on its own is for dry cleaners, not you. The letter inside tells the cleaner which solvents are safe.

• A means any solvent.
• P means the common dry cleaning solvents (the most widely used is perchloroethylene) are safe.
• F means petroleum or hydrocarbon solvent only, a gentler class.
• W means professional wet cleaning: water-based cleaning done by a professional with specialized equipment and detergents.
• A line under the circle means a mild process. An X through it means do not dry clean.

"Dry clean" versus "dry clean only"

These are not the same. "Dry clean" means dry cleaning is a safe method. It doesn't necessarily mean other methods are unsafe; the manufacturer just isn't vouching for them. "Dry clean only" is a warning. It means water, agitation or both are likely to damage the garment. There's more on why in why some pants say dry clean only.

If the label is gone

Treat the pants as delicate. Cold water, gentle cycle, inside out, air dry. That route rarely hurts anything. If the pants are wool, silk, lined or tailored, don't guess. Take them to a professional, or send them to me and I'll take them to a professional, which is a sentence I recognize is not a great argument for my existence.

What dry cleaning actually is

Dry cleaning is not dry. Clothes are cleaned in a machine, with a liquid, and tumbled. The difference is that the liquid is a solvent instead of water. The most common solvent in the U.S. has long been perchloroethylene, with hydrocarbon, silicone-based and liquid carbon dioxide systems as alternatives. Many cleaners also offer professional wet cleaning, which uses water with computer-controlled machines, specialized detergents and tension-finishing equipment that holds the garment's shape as it dries.

Solvents dissolve oils and grease well, and they don't make fibers swell the way water does. That second part is the important one.

Fabrics that don't like water

Wool

Wool fibers are covered in tiny overlapping scales. Add warm water and agitation and those scales lock together. This is felting, and it's permanent. A pair of wool trousers can come out of a hot wash noticeably smaller, thicker and stiffer. Some wool is treated to resist this and labeled machine washable. Most tailored wool trousers aren't.

Rayon and viscose

Rayon is made from wood pulp and loses a large share of its strength when wet. It can shrink, stretch out of shape or tear more easily in the wash, and some rayon changes texture after one wash in a way that doesn't reverse.

Silk

Silk can water-spot, lose its sheen and bleed dye. Some silk is washable by hand. A lot of silk trousers use dyes and finishes that aren't.

Acetate

Often used in linings. Acetate is sensitive to heat and wrinkles permanently if it's handled hot and wet.

Construction that doesn't like water

Sometimes the fabric is fine and the problem is how the pants are built.

• Linings. If the shell and the lining are different fibers, they can shrink at different rates. The pants pucker and hang wrong.
• Interfacing. The stiff layers inside waistbands and fly fronts are sometimes fused with adhesive that softens or bubbles in hot water.
• Pleats and creases. Sharp pleats are often heat-set. Washing can soften them.
• Trims. Beading, sequins, leather patches and some buttons don't survive a washing machine, or damage everything else in it.

So can you ever ignore the label?

People do, sometimes successfully. A polyester dress pant labeled "dry clean" may wash fine on a delicate cycle. But you're taking on the risk yourself, and the downside with wool, rayon and lined tailoring is that the damage is permanent. If the trousers matter to you, the label is cheaper than replacement.

Making dry-clean-only pants last

• Clean them less. Dry cleaning is gentle but not nothing. Brush wool trousers after wearing and hang them to air out. They'll need cleaning less often than you think.
• Deal with spills immediately. Blot, don't rub, and don't add water to a stain on a dry-clean-only fabric unless you know it's safe.
• Hang them properly. Clamp hangers at the hem or cuff, or fold over a wide bar hanger along the crease.
• Tell the cleaner what the stain is. Knowing it's oil versus wine changes the treatment.

How I handle them

Dry-clean-only pants are Special Pants. They go to professional cleaning using the process the label specifies, and they're pressed where they should be. It costs more than washing jeans, because it is more than washing jeans. Pricing is here.

Some pants go in a washing machine. Some pants apparently require chemistry. I'll deal with both.

Why cotton shrinks

When cotton is spun and woven, the fibers are stretched under tension. Water and heat let that tension release, and the fabric contracts. Most jeans are "sanforized," or pre-shrunk, at the mill, which means this has mostly already happened. Sanforized denim typically shrinks very little after that. Unsanforized denim, sometimes sold as "shrink-to-fit," can shrink considerably on its first wash, which is what it's designed to do.

Check the tag or the product description. If it doesn't mention either, it's almost certainly sanforized.

The safest way: line dry

1. Take them out promptly. Don't leave wet jeans balled up in the machine, where creases set in.
2. Shake them out. A few firm snaps straighten the legs and loosen wrinkles.
3. Keep them inside out. This protects the color, especially if they'll be in sunlight.
4. Hang them by the waistband with clips, or fold them over a line or drying rack at the knees. Hanging by the waistband uses the weight of the wet legs to keep length.
5. Keep dark denim out of direct sun. UV light fades indigo. Shade or indoors is better.

Expect jeans to take most of a day to dry indoors. They'll feel stiff. Wearing them for ten minutes fixes that, or a few minutes in the dryer on no heat.

If you use a dryer

• Use low heat, or no heat at all.
• Take them out while slightly damp and hang them to finish. Most shrinkage and heat damage happens in the last stretch of a dryer cycle, when the fabric is already dry and still getting hot.
• Never use high heat on stretch denim. It breaks down the elastane, and the jeans lose their recovery for good. You'll know it by the bagging and the tiny white threads poking through the surface.

If they've already shrunk

Cotton shrinkage can often be partly reversed, because the fibers are relaxed rather than damaged.

1. Soak the jeans in lukewarm water. Some people add a little hair conditioner to relax the fibers. It helps some fabrics more than others.
2. Press the water out without wringing.
3. While they're damp, stretch them firmly: pull the legs lengthwise and the waistband outward. Work in sections.
4. Hang or lay them flat to dry, and stretch again partway through.

Or put them on damp and wear them until they dry. This works. It's also unpleasant, and I don't recommend it in winter.

What I do

Everyday Pants are dried the way the label and the fabric suggest, which for most jeans means low heat or no heat and finishing on a rack. If you want your jeans line dried only, say so. If your jeans are unsanforized and you want them shrunk on purpose, also say so. That's a sentence I didn't expect to write, but I'm prepared for it.

What actually fades black fabric

• Friction. Fibers rubbing against each other, the drum and zippers break off tiny bits of dyed surface. The fabric looks lighter because it's slightly fuzzy.
• Heat. Hot water and high dryer heat help dye leave the fiber.
• Detergent residue. Too much detergent can leave a film that looks dull and chalky on dark fabric.
• Sunlight. UV breaks down many dyes. Drying black pants in the sun is a quick way to make them brown-ish.
• Chlorine bleach, including the bleach in some all-in-one detergents and a few stain removers.

What to do instead

1. Wash them inside out. The inside takes the friction. The outside stays dark.
2. Use cold water. Modern detergents work well cold, and cold water holds dye in better.
3. Use a detergent made for darks, or at least one without optical brighteners. Brighteners are designed to make whites look whiter and can leave a slight haze on black.
4. Use less detergent than you think. Follow the dose on the cap for the load size, not the size of the cap.
5. Choose a shorter, gentler cycle. Less time tumbling means less friction.
6. Wash with other darks, and keep lint-shedding items like towels out of the load.
7. Skip the dryer, or use low heat and pull them early. Dry indoors or in shade.
8. Wash less often. Air them out between wears. Spot clean small marks.

Myths worth dropping

Vinegar sets the dye. Vinegar is used to help fix certain dyes on wool and silk in dyeing processes. Commercially dyed cotton pants are colored with dyes that don't work that way, and a splash of household vinegar in the wash won't lock them in. It may help rinse out detergent residue, which can make fabric look slightly less dull. That's about all.

Salt stops bleeding. Salt is used during some dyeing processes, not after. Adding it to your wash doesn't fix the dye in finished garments.

Coffee or black tea redyes them. It stains them brown. Slightly. Unevenly. No.

When they've already faded

A fabric dye made for the fiber can restore black cotton reasonably well. Synthetic blends and polyester are much harder to redye at home. Either way, redyeing is a project. Prevention is easier.

What I do

Black and dark pants get turned inside out, washed cold in a detergent suited to darks, and kept out of high heat. They go home looking the same color they arrived. I can't make them darker than they arrived. I'm working on accepting that.

First, the universal rules

• Act quickly. Fresh stains are far easier than old ones.
• Blot, don't rub. Rubbing pushes the stain deeper and roughs up the fabric.
• Work from the outside in, so you don't spread the stain into a bigger ring.
• Test anything on a hidden spot first, like the inside of a hem.
• Don't put a stained garment in the dryer. Heat sets most stains. If it's still there after washing, treat and wash again before drying.
• Check the care label. None of the steps below apply to dry-clean-only fabrics. Blot and take it to a professional.

Protein stains: blood, sweat, egg, dairy, grass (partly)

Use cold water. Hot water cooks protein into the fibers, the same way it cooks an egg. Rinse from the back of the fabric, then work in a detergent containing enzymes (most mainstream liquid detergents do), let it sit, and wash cold.

Oil and grease: food, cooking oil, makeup, bike chain

Oil doesn't dissolve in water, so water alone does little. Blot excess, then cover the spot with an absorbent powder like cornstarch or baby powder for fifteen minutes and brush it off. Work in a little liquid dish detergent, which is designed to break up grease, then wash in the warmest water the care label allows.

Tannin stains: coffee, tea, wine, juice, soda

Flush with cold water from the back as soon as possible, then apply liquid laundry detergent and wash. Avoid bar soap and other true soaps on these; they can make tannin stains harder to remove. If a faint mark remains on colorfast fabric, an oxygen-based (non-chlorine) bleach soak often helps.

Dye stains: ink, marker, dye transfer, some grass

These are the hardest because a dye stain is literally dyeing your pants. Ballpoint ink often responds to rubbing alcohol dabbed on with a cloth (test first; alcohol can lift the pants' own dye too). Permanent marker is frequently permanent, as advertised. Dye transfer from new jeans onto lighter pants can sometimes be lifted with a color-run remover, but only on fabrics that can take it.

Things that make stains worse

• Hot water on protein stains.
• Chlorine bleach on colored fabric. You'll remove the stain and the color around it.
• Scrubbing with a rough brush on delicate or dark fabric.
• Mixing stain products. Some combinations, like bleach with ammonia or with vinegar, release dangerous gases. Use one thing at a time and rinse between.
• Ironing over a stain. Heat again.

When a stain is permanent

Some are. A stain that's been through a hot dryer, an old oil stain that's oxidized yellow, bleach spots (which are missing color, not added color) and heavy dye transfer often can't be fully removed without damaging the fabric. A good cleaner knows when to stop.

What I promise, and what I don't

Every pair I receive gets inspected, and visible stains get treated using the approach suited to the stain and the fabric. If you know what a stain is, tell me in your order. It genuinely helps.

What I don't promise is that every stain comes out. Nobody honest can. Stain removal is not guaranteed. I'll make a reasonable effort. I cannot undo the events that caused your stain.

The one question

This entire company rests on one question: will people actually mail their pants to someone?

I have strong feelings about the answer. Strong feelings are not data. So before buying more equipment, arranging professional cleaning partners, building an ordering system and writing shipping workflows, I'm asking.

What the form is actually for

When you tell me about your pants, a few things happen. I learn how many pairs people would realistically send at once, which decides box sizes and whether the Pants Like Company discount matters. I learn what kind of pants, which decides how much specialty cleaning capacity to line up. I learn how often, which decides whether this is a novelty or a habit. And I learn what you'd expect to pay, which is the part I'm most nervous about.

The ZIP code isn't for anything sinister. It tells me where demand is, which affects shipping costs and where it makes sense to start.

What you get for answering

You're on The Pants List. You'll hear when ordering opens, before anyone else. You'll get early access and introductory offers, and the earliest members are in line for Founding Pants status, which I'll define properly before launch rather than inventing perks now that I can't deliver.

What happens next

If enough people say yes, I start washing pants. If not very many people say yes, I'll have learned something valuable about America and its pants, and I'll tell you what I learned.

Either way, thank you for reading a company blog post about whether a company should exist. It's an unusual genre.
