Quick Answer: Wash linen in cold or lukewarm water (30C max) on a gentle cycle with mild liquid detergent. Do not use bleach or fabric softener. Air dry flat for best results, or tumble dry on the lowest heat setting. Linen shrinks 3-10% on its first wash, so expect some size change. After the first few washes, it stabilises and actually gets softer with each laundry cycle.

Linen has a reputation for being fussy to care for. It wrinkles. It shrinks. It costs enough that you worry about ruining it. But the truth is that linen is one of the easiest natural fabrics to maintain once you understand a few basic rules. We have covered why linen shrinks and how to prevent it in a separate guide. This one focuses on the actual washing process for everything from linen clothes to linen bedding.
It sits alongside the rest of our natural-fibre bedding wall in Brantford, linen, bamboo, silk, and Canadian-filled down under one roof.
At Mattress Miracle in Brantford, we deal with fabric care questions daily because people want their bedding to last. Linen, when cared for properly, can last 20-30 years. Cared for badly, it can look worn and misshapen within months. The difference is almost entirely in how you wash and dry it.
Before You Wash: What to Know About Linen
Linen is made from flax fibres, which behave differently from cotton, polyester, or silk in the wash. Understanding these differences will save you from most laundry mistakes.
Linen gets stronger when wet. Unlike silk or wool, which weaken when wet, flax fibres actually increase in tensile strength by about 20% when saturated with water. Research published in the Journal of Natural Fibres (2018) confirmed that wet linen is more resistant to tearing than dry linen. This means you do not need to baby it in the wash the way you would with silk. It can handle machine washing without falling apart.
Linen shrinks on the first wash. Expect 3-10% dimensional change during the initial washes. This is well-covered in our linen shrinkage guide, but the key takeaway for washing purposes is: cold water and air drying minimise shrinkage, while hot water and high-heat tumble drying maximise it.
Linen softens with every wash. New linen can feel stiff or crispy. This is normal. The natural pectin and wax in flax fibres create that initial stiffness, and each wash cycle breaks down these compounds, leaving the fabric progressively softer. By the tenth wash, most linen feels like butter. This is the opposite of cotton, which starts soft and can roughen over time.
Linen wrinkles. Accept it. Flax fibres have low elasticity, which means they do not bounce back from compression the way cotton or synthetic fibres do. Wrinkles are part of linen's character. You can iron them out if you want, but many people appreciate the relaxed, textured look of naturally wrinkled linen.
Why Linen Gets Softer
The softening process in linen is chemical, not just physical. Research in Cellulose journal (2020) found that repeated washing gradually removes the pectin and lignin compounds that bind flax fibres together. As these compounds wash away, the individual fibres become more mobile within the yarn, creating a softer, more supple fabric. This process is self-limiting: once the excess binding compounds are gone, the fabric reaches a stable softness that persists for years. This is why vintage linen feels so remarkably soft.

How to Machine Wash Linen
Machine washing is perfectly fine for most linen items. Here is the step-by-step process.
Step 1: Sort and prepare
- Separate linen by colour: whites, lights, and darks. Linen dyes can bleed, especially in the first few washes.
- Turn garments inside out to protect the outer surface from abrasion.
- Close all zippers and buttons to prevent snagging.
- Check pockets (you would be surprised how often this gets skipped).
- For delicate items like linen dresses or blouses, place them in a mesh laundry bag.
Step 2: Select your wash settings
| Setting | Recommended | Why |
|---|---|---|
| Cycle | Gentle / Delicate | Reduces mechanical agitation that causes shrinkage and wrinkles |
| Water temperature | Cold or lukewarm (30C max) | Hot water increases shrinkage by up to 60% |
| Spin speed | Medium (800-1000 RPM) | High spin compresses fibres and creates deep wrinkles |
| Water level | High (if selectable) | Linen needs room to move freely. More water = less abrasion |
Step 3: Choose your detergent
Use a mild, pH-neutral liquid detergent. About half the amount you would use for a cotton load is sufficient because linen releases soil more easily than cotton.
Do not use:
- Bleach (chlorine or oxygen). Bleach breaks down cellulose fibres, weakening linen over time. Even "colour-safe" oxygen bleach accelerates fibre degradation.
- Fabric softener. Softener coats fibres with a waxy film that reduces linen's natural breathability and moisture absorption. Linen softens naturally with washing, so added softener is unnecessary and counterproductive.
- Powder detergent. Can leave granular residue trapped in the weave, especially in open or textured weaves. Liquid dissolves more completely.
Step 4: Load the machine
Fill the drum no more than half full. Linen needs room to circulate in the water. Overcrowding causes friction between items, which creates wrinkles, pilling, and uneven washing. It also traps detergent in folds where water cannot rinse it out.
Wash linen with other linen or lightweight natural fabrics. Do not wash linen with heavy items like jeans or towels. The weight difference causes the lighter linen to get battered by the heavier items during the cycle.
Step 5: Remove promptly
Take linen out of the washing machine as soon as the cycle finishes. Leaving wet linen bunched up in the machine creates deep creases that are difficult to remove and can develop a musty smell surprisingly quickly, especially in humid weather.
Dorothy, Sleep Specialist: "The biggest mistake people make with linen is treating it like cotton. They throw it in with everything else on a normal cycle, use regular detergent amounts, and then wonder why their nice linen sheets feel stiff and look wrinkled. Linen needs gentler treatment but less detergent. Once you adjust those two things, it practically takes care of itself."
How to Hand Wash Linen
Hand washing is ideal for delicate linen garments, structured pieces with linings, or items you want to treat with extra care. Here is how.
- Fill a basin or sink with lukewarm water (no hotter than 30C).
- Add a small amount of mild liquid detergent. A teaspoon is usually enough for a single garment.
- Submerge the linen and gently swish it through the water for 3-5 minutes. Do not scrub, twist, or wring the fabric.
- Let it soak for 10-15 minutes if the item is noticeably soiled.
- Rinse thoroughly in clean lukewarm water until no soap remains. You may need to change the rinse water two or three times.
- Remove excess water by pressing the linen gently between clean towels. Roll the garment in a dry towel and press down. Do not wring or twist.
- Reshape while damp and lay flat to dry or hang on a padded hanger.
Hand washing is particularly recommended for linen dresses with structural details (pleats, tucks, seaming) that could shift in a washing machine. It is also the safest method for the first wash of any new linen garment, when you are unsure how much it will shrink.
How to Wash Specific Linen Items
Different linen products have different considerations. Here is item-by-item guidance.
Linen clothes (shirts, pants, casual wear)
Machine wash on gentle cycle, cold water. Turn inside out. Use a mesh bag for items with buttons or delicate details. Air dry on a hanger or flat. Iron on the reverse side while slightly damp if you want a crisp look.
Linen dresses
This is the item people worry about most. A linen dress can cost $150-$400, and the thought of shrinking it is stressful. For the first wash, hand wash to assess shrinkage. After you know how the fabric behaves, you can usually switch to machine washing in a mesh bag on gentle cycle. Always hang or lay flat to dry. A padded hanger prevents shoulder bumps.
Linen sheets and bedding
Machine wash is fine and practical for sheets. Use the gentle cycle with cold water. Wash sheets separately from clothing to prevent tangling. Quality linen sheets can handle regular machine washing for years. We recommend washing linen sheets every 7-14 days, which is the same frequency recommended by the Canadian Sleep Society for all bedding types.
Linen tablecloths and napkins
Pre-treat any food stains before washing (see stain removal section below). Machine wash on gentle cycle. For white linen tablecloths, you can use slightly warmer water (up to 40C) for better stain removal, accepting the minor additional shrinkage. Linen napkins and tablecloths benefit from ironing while damp for a polished look. Our linen napkins guide covers care in more detail.
Linen curtains and shower curtains
Remove hardware before washing. Machine wash on gentle cycle, cold water. Rehang while damp and let them air dry in place. Gravity will pull out most wrinkles as they dry. For linen shower curtains, wash monthly to prevent mildew buildup.
Drying Linen Properly
How you dry linen matters as much as how you wash it. Heat is linen's enemy when it comes to shrinkage and fibre damage.
Air drying (recommended)
Flat drying is best for garments where you want to maintain shape and dimensions. Lay the item on a clean, dry towel on a flat surface. Reshape while damp. Flip halfway through drying.
Line drying works well for sheets and larger items. Hang in the shade rather than direct sunlight, which can fade colours and weaken fibres over time. In Canada, line drying is seasonal (roughly May through September in southern Ontario), so you will need alternatives for winter months.
Winter Drying Solutions for Canadian Linen Owners
From November through March, outdoor drying is not practical in most of Ontario. Use a folding drying rack near a heating vent or in a room with good air circulation. Linen dries faster than cotton because flax fibres release moisture more efficiently. A linen shirt will dry on an indoor rack in 3-4 hours in a heated home. Linen sheets take 5-7 hours. If you have a dehumidifier, running it in the drying room speeds things up considerably.
Machine drying (use with caution)
If you must use a dryer:
- Use the lowest heat setting (air fluff or tumble dry low)
- Remove the linen while still slightly damp (not bone dry)
- Shake each piece out and smooth wrinkles immediately
- Never use dryer sheets with linen (they coat the fibres)
High heat tumble drying can add 5-8% additional shrinkage on top of whatever the wash cycle caused. Over time, repeated high-heat drying weakens flax fibres and shortens the fabric's lifespan significantly. The American Association of Textile Chemists and Colorists (AATCC) testing data shows that linen dried at high heat for 50 cycles loses approximately 15% of its tensile strength compared to air-dried linen.
Ironing and Wrinkles
Linen wrinkles. This is a feature, not a flaw, but we understand that some occasions call for smooth linen.
How to iron linen
- Iron while the linen is still slightly damp (or mist with water from a spray bottle)
- Use medium-high heat (linen setting on most irons)
- Iron on the reverse side to prevent shine marks
- Use a pressing cloth for dark colours to prevent heat marks
- Iron in long, smooth strokes rather than pressing down hard in one spot
Steam as an alternative
A garment steamer is gentler than ironing and works well for removing major wrinkles from linen garments. It will not give you the crisp, flat finish of ironing, but it will smooth out the worst creases. Hang the garment and steam from top to bottom, keeping the steamer head slightly away from the fabric.
Talia, Showroom Specialist: "I own a lot of linen, and I never iron it. The wrinkled look is the entire point. If someone wants perfectly smooth bedding, I would suggest a cotton sateen instead. Linen is meant to look relaxed and lived-in. Embrace it."
Stain Removal on Linen
Treat stains as soon as possible. Linen's absorbent nature means stains set quickly, but the open weave structure makes them easier to flush out if you act fast.
| Stain Type | Treatment | Notes |
|---|---|---|
| Red wine | Blot immediately. Apply salt to absorb. Rinse with cold water. Soak in white vinegar solution (1:3 ratio) for 30 minutes. | Do not use hot water or it will set the stain permanently. |
| Coffee / tea | Rinse with cold water immediately. Apply mild detergent directly to stain. Let sit 10 minutes, then wash as normal. | Old coffee stains may need an overnight soak in cold water with detergent. |
| Oil / grease | Sprinkle baking soda or cornstarch on the stain to absorb oil. Let sit 30 minutes. Brush off. Apply dish soap directly. Wash in warm water. | Warm water is acceptable here because oil-based stains need heat to dissolve. |
| Blood | Soak in cold water immediately. Apply hydrogen peroxide (3%) on white linen. For coloured linen, use salt water soak. | Never use hot water on blood stains. Heat sets the protein permanently. |
| Perspiration yellowing | Soak in a mixture of white vinegar and water (1:4) for one hour. Wash as normal. Repeat if needed. | Prevent by washing linen before extended storage. |

Common Mistakes That Damage Linen
Avoid these, and your linen will last decades rather than months.
1. Using too much detergent. Excess detergent does not get rinsed out of linen's open weave structure. It builds up over time, making the fabric stiff, dull, and prone to attracting dirt. Use half the amount you normally would.
2. Washing with rough fabrics. Denim, towels, and items with metal hardware will abrade linen in the machine. Wash linen with similar weight fabrics only.
3. Wringing wet linen. Twisting linen to remove water breaks down the fibres at the twist points, creating weak spots that will eventually tear. Press water out with towels instead.
4. Storing linen while damp. Even slightly damp linen can develop mildew surprisingly fast, especially in Canadian basements or closets without good ventilation. Make sure linen is completely dry before folding and storing. Our mould prevention guide covers the conditions that encourage mildew growth.
5. Using bleach on stains. Chlorine bleach does remove stains from linen, but it also breaks down the cellulose fibres that give linen its strength. Every bleach application weakens the fabric. Over time, bleached linen develops thin spots and holes. Use white vinegar or hydrogen peroxide instead.
6. Dry cleaning unnecessarily. Most linen does not need dry cleaning. The solvents used in dry cleaning can actually be harsher on flax fibres than water. Unless the care label specifically says "dry clean only" (usually due to structural elements or linings, not the linen itself), machine or hand washing is better for the fabric.
How Often to Wash Linen
| Item | Recommended Frequency | Reasoning |
|---|---|---|
| Linen sheets | Every 7-14 days | Linen resists bacteria better than cotton, so every two weeks is fine for most people |
| Linen pillowcases | Every 5-7 days | Face contact means more oil and bacteria transfer |
| Linen shirts / tops | After 2-3 wears | Unless visibly soiled or sweaty, linen stays fresh longer than cotton |
| Linen pants / skirts | After 3-5 wears | Lower-body garments accumulate less sweat and oil |
| Linen dresses | After 2-3 wears | Depends on weather and activity level |
| Linen tablecloths | After each use (if food contact) or monthly | Food stains set quickly on linen |
| Linen napkins | After each use | Food and mouth contact |
Linen has natural antibacterial properties that persist even after processing (unlike bamboo rayon, where those properties are largely lost during manufacturing). A 2019 study in the Journal of Medical Microbiology found that linen fabrics inhibited bacterial growth 30-40% more effectively than cotton fabrics under identical conditions. This means linen stays fresher between washes than cotton, which is both convenient and better for the fabric's longevity.
Brad, Owner, 40+ years of experience: "The old advice used to be that linen was delicate and needed special handling. It is not delicate. It is one of the strongest natural fabrics in the world. Flax fibres are three times stronger than cotton. What linen needs is gentle treatment, not because it is weak, but because harsh treatment causes shrinkage and stiffness that ruin the qualities you are paying for. Treat it gently and it will outlast everything else in your linen closet."

Can you machine wash linen clothes?
Yes, most linen clothes can be machine washed on a gentle cycle with cold or lukewarm water and mild liquid detergent. Always check the care label first, as some lined or structured linen garments may require dry cleaning due to the non-linen components. Turn garments inside out, use a mesh laundry bag for delicate items, and avoid overloading the machine.
Can you put linen in the dryer?
You can put linen in the dryer on the lowest heat setting, but air drying is better for preserving the fabric's dimensions and strength. High heat causes significant shrinkage (up to 8% additional) and weakens flax fibres over time. If you use a dryer, remove the linen while still slightly damp and smooth or fold immediately to minimise wrinkles.
Do you need special detergent for linen?
No, but choose a mild, pH-neutral liquid formula. Avoid powder detergents (they leave residue), bleach (it weakens cellulose fibres), and fabric softener (it coats fibres and reduces breathability). Use about half the detergent amount you would for cotton, as linen releases soil easily and excess detergent causes buildup.
How do you wash a linen dress without ruining it?
Turn the dress inside out, place it in a mesh laundry bag, and wash on a gentle cycle in cold water with mild liquid detergent. Do not wring or twist. After washing, reshape while damp and air dry flat or on a padded hanger. For the first wash, consider hand washing to assess how much the fabric shrinks before committing to machine washing.
How often should you wash linen sheets?
Every one to two weeks during regular use. Linen naturally inhibits bacterial growth more effectively than cotton, so it stays fresher between washes. In summer, weekly washing may be more comfortable due to higher perspiration. Washing linen regularly actually improves it, as each cycle softens the fabric and does not degrade it when done properly.
