Washing knitted clothes can feel confusing, especially if you want your favorite sweater or handmade scarf to last a long time. Many people make mistakes that damage the shape, stretch the fabric, or cause pilling. In reality, caring for knits is about understanding the material and using gentle methods.
If you follow the right steps, your knitted clothes will stay soft, warm, and beautiful for many years.
This guide explains everything you need to know about how to wash knitted clothes. Whether your item is made from wool, cotton, acrylic, or a special blend, you’ll learn the best way to clean it without causing harm. By the end, you’ll have practical tips, cleaning techniques, and even some lesser-known tricks to keep your knits looking their best.
Understanding Knitted Fabrics
Before you start washing, it’s important to know what makes knitted clothes special. Unlike woven fabrics, knitted items are made by looping yarn together. This creates a stretchy, flexible structure that feels cozy but is also more delicate.
There are many types of yarn used in knits:
- Wool: Warm, soft, can shrink easily.
- Cotton: Breathable, less stretchy, but can lose shape.
- Acrylic: Durable, easy to wash, but can pill.
- Blends: Combine properties of two or more fibers.
Each material reacts differently to washing. For example, wool can shrink in hot water, while cotton may stretch out. Some blends are machine-washable, but most hand-knitted or delicate items need special care.
Non-obvious insight: The way a knit is made (tight or loose stitches) also matters. Loosely knitted items stretch more easily and need gentler washing.
Why Knitted Clothes Need Special Care
Knitted clothes are not just about the yarn—they’re about the structure. When you wash a knit, water can make the fibers swell. If you wring or twist the item, the loops can stretch or break, causing the item to lose shape or develop holes.
Another issue is pilling—small balls of fiber that form on the surface. This happens more with synthetic yarns or blends, but rough washing can make pilling worse on any knit.
Example: A machine-washed wool sweater may come out two sizes smaller and stiffer, or a cotton cardigan may lose its shape and become baggy.
Taking time to wash knits properly prevents these problems and extends the life of your clothes.
Preparing To Wash Knitted Clothes
Proper preparation makes washing safer and easier.
1. Check The Care Label
Most items have a small tag with washing instructions. Look for symbols or words like “hand wash,” “dry flat,” or “machine wash cold. ” If the label says “dry clean only,” it’s best to follow that advice, especially for expensive or sentimental pieces.
2. Sort By Fiber And Color
Wash similar fibers together. For example, wash all wool items at once. Separate dark and light colors to prevent dye transfer.
3. Inspect For Damage
Check for loose threads, holes, or snags. Fix these before washing, because water can make them worse.
4. Close Zippers And Fasten Buttons
This prevents the item from catching on itself or other clothes.
5. Turn Inside Out
This protects the outside surface from friction, reducing pilling and wear.
6. Remove Excess Dirt
Gently shake out dust or brush off any debris before washing.
Hand Washing Knitted Clothes
Hand washing is the safest way to clean most knitted items, especially hand-knitted or delicate pieces. Here’s how to do it right:
Step-by-step Instructions
1. Fill A Basin With Cold Or Lukewarm Water
Use a clean sink, tub, or large bowl. Water should never be hot, as this can shrink or damage fibers.
2. Add Gentle Detergent
Use a small amount of mild detergent made for wool or delicates. Regular laundry soap can be too harsh.
3. Submerge The Garment
Place the item in the water, gently pressing it down so it’s fully soaked. Don’t twist or scrub.
4. Soak For 10–15 Minutes
Let the item rest so the detergent can lift dirt and oils.
5. Gently Agitate
Swish the garment around with your hands. Be careful not to stretch the fabric.
6. Rinse Thoroughly
Drain the soapy water and refill the basin with clean water. Swish the item to remove all soap. Repeat until water runs clear.
7. Remove Excess Water
Lift the garment out, supporting its weight. Squeeze gently—never wring. Lay flat on a clean towel, roll up the towel with the item inside, and press to absorb more water.
8. Reshape And Dry Flat
Lay the item flat on a dry towel or mesh rack, shaping it to its original size. Avoid hanging, which stretches the fabric.
Why Hand Washing Works
Hand washing lets you control water temperature, movement, and detergent. This gentle process prevents stretching, shrinking, or felting—common problems with machine washing.
Non-obvious insight: Even if a label says “machine washable,” hand washing will always extend the life of your favorite knits.

Machine Washing Knitted Clothes
Some modern knits can handle machine washing, but you must use the right settings and techniques.
How To Wash Knits In A Machine
1. Choose The Right Cycle
Use the “delicate” or “wool” cycle, which has slower spins and less agitation.
2. Use Cold Water
Hot water can shrink or damage knits, so always choose cold.
3. Select A Mild Detergent
Avoid bleach or strong detergents. Special wool or delicate formulas are best.
4. Protect With A Mesh Bag
Place the knit item inside a mesh laundry bag to prevent snagging and reduce friction.
5. Do Not Overload The Machine
Wash only a few items at once to avoid stretching.
6. Skip The Spin Cycle (if Possible)
If your washer allows, use the lowest spin setting or stop before the spin begins.
7. Dry Flat Immediately
Remove the garment as soon as the cycle finishes and lay it flat to dry. Do not hang.
Comparing Hand And Machine Washing
Here’s a simple look at the pros and cons:
| Method | Pros | Cons |
|---|---|---|
| Hand Wash | Gentle, best for delicate or handmade items, less risk of damage | Time-consuming, more effort needed |
| Machine Wash (Delicate) | Quick, convenient for modern knits, consistent cleaning | Risk of stretching, shrinking, or pilling if not careful |
Choosing The Right Detergent
Detergent matters more than most people think. The wrong detergent can strip oils from wool or roughen cotton fibers.
What To Look For
- Mild Formula: Look for labels like “for wool,” “for delicates,” or “baby clothes.”
- No Bleach or Fabric Softener: These can damage natural fibers and cause buildup.
- Low Residue: Detergents that rinse clean prevent itchiness or residue.
Popular Detergent Types
| Detergent Type | Best For | Notes |
|---|---|---|
| Wool Wash | Wool, cashmere, alpaca | Very gentle, often contains lanolin for softness |
| Delicate Laundry Detergent | Cotton, acrylic, blends | Safe for all knits, avoids harsh chemicals |
| Regular Detergent | Sturdy synthetic knits | Use with caution; always dilute |
Pro Tip: Never pour detergent directly onto the garment. Always mix it into water first.
Drying Knitted Clothes The Right Way
How you dry knits matters as much as how you wash them. The wrong drying method can ruin a garment—even if you washed it perfectly.
Steps For Proper Drying
1. Lay Flat To Dry
Place the washed item on a dry towel or a mesh drying rack. Shape it gently with your hands to its original size.
2. Avoid Hanging
Hanging makes knits stretch, especially around the shoulders or neck.
3. Keep Away From Heat
Never put knits in the dryer or near direct sunlight, heaters, or radiators. High heat can shrink, fade, or damage fibers.
4. Change Towels If Needed
If the towel becomes soaked, move the garment to a fresh, dry towel to speed up drying.
5. Allow Enough Time
Some thick knits take 24–48 hours to dry completely. Be patient.
Air-drying Vs. Machine Drying
| Method | Effect on Knits | Best For |
|---|---|---|
| Air Dry (Flat) | No stretching, preserves shape, prevents shrinkage | All knitted items, especially wool |
| Machine Dry | High risk of shrinkage, fading, and pilling | Not recommended for any knits |
Non-obvious insight: If you must speed up drying, use a fan in the room, but never direct hot air at the garment.
Removing Stains From Knitted Clothes
Stains on knitted clothes can be tricky, but with quick action, most can be removed without harm.
General Steps
1. Act Fast
Treat stains as soon as possible. The longer they sit, the harder they are to remove.
2. Blot, Don’t Rub
Use a clean towel to blot up liquids. Rubbing can push the stain deeper and damage stitches.
3. Use A Gentle Stain Remover
Apply a small amount of mild detergent or a special stain remover for delicates. Test on a hidden spot first.
4. Soak If Needed
For tough stains, soak the item in cold water with detergent for up to 30 minutes.
5. Rinse Thoroughly
Rinse with cold water until all soap is gone, then wash as usual.
Common Stain Examples
- Oil/Fat: Sprinkle with cornstarch, let sit, then brush off and wash.
- Wine/Coffee: Blot, rinse with cold water, and use gentle detergent.
- Blood: Soak in cold water, never hot, and treat with detergent.
Pro Tip: Never use bleach or harsh chemicals on knits. They can weaken fibers and cause discoloration.
Storing Knitted Clothes After Washing
Proper storage keeps knits in good shape between wears.
1. Fold, Don’t Hang
Hanging stretches out shoulders and necklines. Fold knits neatly and store in drawers or on shelves.
2. Store Clean
Always wash knits before storing for a season. Dirt or sweat can attract moths and cause stains to set.
3. Use Lavender Or Cedar
Place natural moth repellents like lavender sachets or cedar blocks with your knits.
4. Allow Air Circulation
Store in breathable cotton bags, not plastic, to prevent moisture buildup and mildew.
5. Check Periodically
Look for signs of moths or mildew, especially if you store knits for many months.
Special Tips For Different Types Of Knitted Clothes
Knitted clothes come in many forms, and each may need a slightly different approach.
Wool And Cashmere
- Use cold water and special wool detergent.
- Never wring or twist.
- Add a splash of white vinegar to the final rinse for extra softness.
Cotton
- Can handle slightly warmer water but avoid hot.
- Shape carefully after washing, as cotton stretches when wet.
Acrylic
- More durable, but still avoid high heat.
- Machine wash on delicate, but dry flat.
Hand-knitted Items
- Always hand wash unless the yarn label says otherwise.
- Take extra care when lifting wet items—they are heavy and stretch easily.
Synthetics And Blends
- Follow the care label, as some blends can be machine washed.
- Use a mesh bag and delicate cycle for safety.
Non-obvious insight: Some knitters “block” garments after washing—stretching and pinning them to shape while damp. This is especially common for shawls and lace items.

Mistakes To Avoid When Washing Knitted Clothes
Even with good intentions, some mistakes can ruin your favorite knits. Here are common errors to avoid:
1. Using Hot Water
Hot water shrinks and felts wool, and can break down other fibers.
2. Wringing Out Water
Twisting stretches and distorts the fabric, causing permanent damage.
3. Hanging To Dry
Hanging stretches out the garment, especially heavy sweaters.
4. Using The Wrong Detergent
Strong detergents strip natural oils and weaken fibers.
5. Ignoring The Care Label
Always check the label; some blends or special finishes need unique care.
6. Not Rinsing Thoroughly
Soap residue can make knits stiff or itchy.
7. Storing While Damp
Damp knits attract mildew and can develop bad smells or mold.
8. Overloading The Washer
Too many items in the machine can cause friction and stretching.
9. Skipping Mesh Bags
Loose knits can snag or tangle in the wash.
10. Drying In The Sun
Sunlight can fade colors and weaken fibers over time.
Pro Tip: Never use fabric softener on performance yarns (like those with spandex), as it can coat the fibers and affect stretch.
How Often Should You Wash Knitted Clothes?
Many people overwash their knits, which wears them out faster. In fact, most knitted items do not need frequent washing.
- Sweaters: Every 4–6 wears, unless stained or sweaty.
- Scarves and Hats: Once or twice per season.
- Socks and Gloves: After each use, especially if worn directly against skin.
- Blankets: Every few months, or as needed.
Over-washing causes pilling and reduces the lifespan of your garment. Always air out knits between wears to keep them fresh.

Dealing With Pilling And Fuzz
Pilling is when small balls form on the surface of your knit. While it’s hard to prevent completely, you can manage it.
- Use a Fabric Shaver: Special tools remove pills without damaging the knit.
- Hand-Pick Pills: Gently pull off with your fingers.
- Wash Inside Out: Reduces friction and pilling.
Non-obvious insight: Fuzzy halos on mohair or angora are normal and part of the yarn’s character—not a sign of wear.
Eco-friendly Tips For Washing Knitted Clothes
If you care about the environment, small changes can help.
- Use cold water to save energy.
- Choose biodegradable detergents with safe ingredients.
- Air dry instead of using the dryer.
- Wash full loads (if machine washing), but don’t overload.
