Wool sweaters are beloved for their warmth, durability, and natural fibers, but improper washing can lead to shrinkage, stretching, or pilling. Many people shy away from washing wool garments at home due to the risk of damaging the delicate fabric, yet with the right care techniques, wool sweaters can be safely cleaned without worry. This guide will walk you through the best methods to wash wool sweaters—whether you choose to hand wash or machine wash—and provide expert tips on keeping your wool garments in top condition.

Why Wool Needs Special Care
Wool is a natural fiber that requires special handling when it comes to washing. Unlike synthetic materials, wool is prone to shrinking and felting when exposed to high temperatures or harsh chemicals. This happens because the fibers in wool interlock when exposed to heat or agitation, causing them to shrink and lose their softness. Understanding how wool behaves during the washing process is key to preventing these common issues.
Wool is also susceptible to pilling—small, fuzzy balls of fabric that form on the surface of the garment. This occurs when fibers break and tangle together, usually as a result of friction during washing. While pilling is a natural part of a wool sweater’s lifecycle, it can be minimized with proper care.
The lanolin in wool provides natural protection, making it resistant to odors and dirt. This means you don’t need to wash wool as frequently as other fabrics. A well-aired wool sweater can stay fresh for multiple wears before it needs a full wash, reducing the risk of damage from over-washing.
Hand Washing vs. Machine Washing
When it comes to washing wool sweaters, there are two main methods: hand washing and machine washing. Both methods can be effective if done correctly, but it’s important to follow the right procedures to avoid damaging the wool.
How to Hand Wash a Wool Sweater
Hand washing is the safest option for wool sweaters, as it allows for more control over the temperature and agitation. Here’s a step-by-step guide to hand washing your wool garments:
- Fill a basin with cold water: Cold water is essential for wool to prevent shrinking. Fill a basin or sink with enough water to submerge the sweater completely.
- Add a wool-specific detergent: Use a detergent designed for delicate fabrics or wool, such as Woolite or a mild, natural soap. Avoid using regular laundry detergent, as it can be too harsh and strip the wool of its natural oils.
- Gently submerge the sweater: Place your wool sweater in the water and gently press it down to ensure it’s fully submerged. Avoid wringing or scrubbing the fabric, as this can cause stretching or felting.
- Soak for 10–15 minutes: Allow the sweater to soak in the soapy water for 10–15 minutes. This gives the detergent time to lift dirt and oils from the fabric.
- Rinse with cold water: After soaking, drain the soapy water and refill the basin with clean, cold water. Gently swish the sweater around to remove all the detergent. You may need to repeat this step a couple of times to ensure all soap is rinsed out.
- Remove excess water: To remove excess water, gently press the sweater against the side of the basin. Do not wring or twist the fabric. For best results, lay the sweater flat on a clean towel and roll it up to absorb any remaining moisture.
How to Machine Wash a Wool Sweater
While hand washing is the safest method, many modern washing machines have delicate or wool-specific settings that make machine washing an option. Here’s how to wash your wool sweater in a machine:
- Use a mesh laundry bag: Place your wool sweater in a mesh laundry bag to protect it from being pulled or stretched during the wash cycle.
- Select a wool or delicate cycle: Set your washing machine to the wool or delicate cycle, which uses cold water and a gentle spin. Be sure to choose the shortest cycle possible to limit agitation.
- Use a wool-specific detergent: Add a mild detergent designed for wool fabrics. Most washing machines have a separate compartment for liquid detergent, but if you’re using powder, ensure it’s fully dissolved before starting the cycle.
- Skip the spin cycle: If possible, skip or minimize the spin cycle. Excessive spinning can stretch the fibers or cause the sweater to lose its shape.
Drying Wool Sweaters
One of the most important steps in washing wool sweaters is the drying process. Never tumble dry a wool sweater, as the heat and agitation can cause it to shrink. Instead, follow these steps for proper drying:
- Lay the sweater flat: After washing, reshape the sweater to its original size and lay it flat on a clean, dry towel. Avoid hanging the sweater, as this can cause it to stretch out.
- Roll up the towel: Roll the sweater in the towel, pressing gently to remove excess water. Do not wring or twist the sweater.
- Air dry flat: Once the excess water has been removed, lay the sweater flat on a dry towel or drying rack. Ensure it’s in a well-ventilated area but away from direct sunlight, which can fade the colors.
Tips for Preventing Shrinkage
Shrinkage is one of the biggest concerns when washing wool sweaters. To avoid shrinking your wool garments, always use cold water and gentle detergents. Additionally, avoid exposing your wool sweater to heat during washing or drying. When in doubt, stick to hand washing, as this method offers the most control over water temperature and movement.
If your wool sweater does shrink, it’s possible to stretch it back into shape while it’s still damp. Gently pull the fabric in all directions, focusing on the areas that have shrunk the most, such as the arms or torso. Be careful not to overstretch, as this can distort the shape.
How Often Should You Wash a Wool Sweater?
Because wool has natural odor and dirt resistance, wool sweaters don’t need to be washed after every wear. In fact, over-washing can do more harm than good. Unless your sweater is stained or particularly dirty, airing it out between wears is usually enough to keep it fresh. For most wool garments, washing them after every three to five wears is sufficient.
When it comes time to wash, follow the care label on your sweater to ensure you’re using the appropriate washing method. Some wool blends, such as those mixed with synthetic fibers, may be more tolerant of machine washing than 100% wool garments.
How to Treat Stains on Wool Sweaters
Accidents happen, and when a wool sweater gets stained, it’s important to act quickly to avoid permanent damage. Here’s how to handle common stains on wool:
- Blot, don’t rub: If you spill something on your wool sweater, blot the stain gently with a clean cloth or paper towel. Avoid rubbing, as this can push the stain deeper into the fibers.
- Use a mild detergent: For liquid stains, mix a small amount of wool-safe detergent with cold water and gently dab it onto the stain. Rinse with cold water and repeat if necessary.
- For tough stains: If the stain persists, you can create a mixture of water and white vinegar (in equal parts) and apply it to the affected area. Allow the mixture to sit for a few minutes before rinsing thoroughly.
Pilling and How to Manage It
Over time, wool sweaters are prone to pilling, especially in areas that experience frequent friction, such as under the arms or along the sides. Pilling occurs when loose fibers tangle together, forming small balls on the surface of the fabric. While pilling doesn’t damage the sweater, it can make it look worn and less polished.
To remove pills, use a fabric shaver or a sweater comb. Gently glide the tool over the surface of the sweater to remove the pills without damaging the underlying fabric. Avoid using scissors or pulling the pills by hand, as this can create holes in the sweater.
FAQs
Can I put a wool sweater in the dryer?
No, wool sweaters should never be put in the dryer, as the heat will cause them to shrink. Always air dry wool sweaters by laying them flat on a towel.
What detergent should I use for wool?
Use a detergent specifically designed for wool or delicate fabrics, such as Woolite or a natural, mild soap. Avoid regular detergents, as they can be too harsh and strip the wool of its natural oils.
Can I wash wool sweaters in the washing machine?
Yes, but only if your machine has a delicate or wool-specific cycle. Place the sweater in a mesh laundry bag and use cold water with a gentle spin to avoid damage.
How do I remove wrinkles from a wool sweater?
To remove wrinkles from a wool sweater, use a steamer or hang the sweater in the bathroom while you take a hot shower. The steam will help relax the fibers and remove wrinkles without direct heat.
