Let’s be honest—most of us toss on our favorite beanie all winter long without thinking twice about cleaning it. But just like anything you wear regularly, your beanie collects sweat, oils, dirt, and even bacteria over time. The problem? Washing it the wrong way can easily lead to a shrunken, stretched-out mess that no longer fits or feels right.
Whether it’s a wool knit, fleece-lined, or cotton blend, your beanie needs the right kind of care to stay fresh and hold its shape. In this guide, we’ll break down exactly how to wash your beanie—by hand or machine—without ruining it. Because when you treat it right, your beanie will keep you warm (and looking good) season after season.
Understand Your Beanie’s Material
Before you throw your beanie in the wash, take a minute to figure out what it’s actually made of—because that makes all the difference in how you should clean it. Different materials react differently to water, heat, and agitation. Use the wrong method, and you could end up with a beanie that shrinks, stretches out, or loses its shape entirely.
Here’s a breakdown of the most common beanie fabrics and what you need to know before washing:
Wool
Wool beanies are warm, breathable, and cozy—but also delicate. Hot water, rough handling, or a dryer can easily shrink or warp the fibers. These are almost always best washed by hand in cold water with a gentle detergent.

Acrylic
Acrylic is one of the most popular materials for beanies because it’s soft, affordable, and easy to care for. Most acrylic beanies can handle a gentle machine wash, but it’s still smart to use a mesh laundry bag and avoid high heat.
Cotton
Cotton beanies are lightweight and breathable, great for mild weather. They can usually be machine washed, but like all knits, they can still lose shape if not dried properly. Stick to cold water and air drying for best results.

Cashmere or Wool Blends
If your beanie is made from a high-end material like cashmere or a wool blend, proceed with caution. These should either be hand washed with extra care or dry cleaned, depending on the care label.
Fleece
Fleece beanies are built for warmth and durability, and they’re typically machine-washable. Just avoid fabric softeners—they can reduce the fabric’s insulating power.
How to Wash Your Beanie the Right Way
Cleaning a beanie might seem simple, but the wrong approach can quickly ruin its fit, feel, or shape. Below, we break down the safest and most effective methods—whether you prefer hand washing, machine washing, or just need to spot-clean a stain.
1. How to Hand Wash a Knit Beanie (The Safest Method)
Best for: Wool, cashmere, or any beanie labeled “hand wash only”
What You’ll Need:
- Mild detergent (preferably wool- or delicates-friendly)
- Cold or lukewarm water
- Clean towel
Step-by-Step Instructions:
- Fill a basin or sink with cold water and add a small amount of detergent.
- Submerge your beanie and gently swish it around for a few minutes. Don’t rub or scrub harshly—let it soak.
- Drain the soapy water and refill the basin with clean water. Gently rinse the beanie until the water runs clear.
How to Rinse Without Wringing:
Avoid twisting or wringing out the fabric, which can stretch or distort the beanie. Instead, press the water out gently with your hands, then lay the beanie flat on a clean towel. Roll the towel with the beanie inside to blot out excess water.
How to Reshape and Dry Flat:
After blotting, reshape the beanie while it’s still damp. Lay it flat on a dry towel and let it air dry completely. Don’t hang it—gravity will stretch it out.
2. Can You Machine Wash a Beanie?
Short answer: Sometimes—if it’s made from the right material.
When It’s Okay:
Acrylic and cotton-blend beanies are usually safe for the machine as long as you’re careful.
How to Machine Wash Your Beanie Safely:
- Place it in a mesh laundry bag to protect it from stretching and snagging.
- Use cold water and a gentle or delicate wash cycle.
- Avoid fabric softener—it can break down fibers over time.
What Not to Do:
- Never use bleach, even on white beanies—it can damage the material.
- Don’t toss it in a hot dryer—high heat can shrink, warp, or roughen the knit.
3. How to Dry Your Beanie the Right Way
Unless the tag says otherwise, never machine-dry your beanie.
Best Practices:
- Lay it flat on a towel and gently reshape it while it’s still damp.
- Keep it away from direct sunlight or radiators, which can cause shrinkage or fading.
- If you need to speed up drying, place it on a wire drying rack—but make sure it stays flat and supported.
Drying Rack vs. Towel Method:
The towel method is best for preserving the beanie’s shape and avoiding unwanted creases. Drying racks work too, but beanies should never dangle off the edge or they may stretch.
4. How to Spot Clean a Beanie
Sometimes, your beanie doesn’t need a full wash—just a little touch-up.
How to Do It:
- Mix a small amount of mild detergent with cold water.
- Dip a soft cloth or sponge into the solution and gently dab the stained area.
- Use another cloth with plain water to blot and rinse.
- Air dry flat as usual.
This method works especially well for makeup stains, sweat marks, or accidental spills without risking the rest of the beanie.
5. How Often Should You Wash Your Beanie?
It depends on how often you wear it.
- Daily wear: Wash every 1–2 weeks to keep oils, sweat, and odor at bay.
- Occasional use: Once a month or at the end of the season is usually enough.
- Before seasonal storage: Always wash and fully dry your beanie before storing it for months—this prevents musty smells and fabric breakdown.
6. Common Mistakes to Avoid When Washing Your Beanie
Even well-meaning care can backfire. Avoid these all-too-common errors:
- Wringing out your beanie: This can distort the fit and stretch the knit.
- Using hot water: It might feel like a deep clean, but it’s a fast track to shrinkage.
- Hanging it to dry: Wet knit fabric stretches easily—always dry flat.
- Ignoring the material type: Treating wool like acrylic is a recipe for disaster.
Conclusion
Caring for your beanie isn’t complicated—but doing it right makes all the difference. By understanding your beanie’s material, choosing the right cleaning method, and drying it properly, you can avoid shrinkage, stretching, and fabric damage. Whether you hand wash or use a machine, regular maintenance—not just emergency cleaning—keeps your beanie soft, clean, and in great shape all season long. A little extra care goes a long way in making your favorite hat last.
