How to Wash a Wool Sweater: Essential Tips for Long-Lasting Warmth
Love your wool sweaters? They’re your winter best friends—soft, warm, and effortlessly stylish. But one wrong wash can ruin that cozy feel, leaving them shrunken, scratchy, or misshapen.
Don’t worry! We’ve got your back with simple, step-by-step tips on how to wash a wool sweater the right way. Whether it’s a wool sweater for women or men, these easy tricks will keep your favorite knits looking fresh, fluffy, and brand new for seasons to come.
Understanding Wool Types Before Washing
First, check the care label. It tells you what to do. Most wool needs cold water and gentle handling. Turn your sweater inside out. This saves the pretty outside from snags.
Different wools need slightly different care:
-
Merino wool sweater: Soft and delicate; wash in cold water and reshape while damp.
-
Cashmere: Use mild detergent and lay flat to dry.
-
Lambswool: Gentle hand wash only; avoid twisting or wringing.
-
Blended wool: Follow the label—some can handle delicate machine cycles.
Hand Washing: The Safest Method Among All
Hand washing is best for any wool sweater—it helps prevent shrinking and keeps the fabric soft. Plus, it only takes about 15 minutes!
Quick Steps
-
Fill a sink with cold water (not warm!).
-
Add a tiny bit of wool soap. No regular laundry soap.
-
Drop in your wool sweater. Let it soak for 10 minutes.
-
Swish gently. No scrubbing!
-
Rinse with cold water until no soap is left.
-
Lay your sweater flat on a clean towel. Roll it up gently and press to remove excess water—never twist or wring it out!
-
Shape it flat on a dry towel. Let it air dry. Avoid direct sunlight or heat—it can shrink or damage the fibers.
Hand washing works wonders for 90% of wool items and extends their life significantly. Expect no shrinkage if done right!
Machine Washing: When and How to Do It Safely
In a hurry? Some wool sweaters can go in the washing machine—just check the care label first. But skip this step if it’s an alpaca wool sweater; it needs extra gentle care.
Do It Right
-
Pick the wool or delicate cycle.
-
Use cold water only.
-
Add wool soap—just one sweater.
-
Low spin. Add vinegar to the rinse for extra softness.
-
Pull it out fast. Lay flat to dry.
Test with a small hidden area first. Machine washing saves time but increases shrinkage risk by 20-30% if not done carefully. Handle with care to keep your sweater in perfect shape.

Top Tips to Avoid Shrinkage
Shrinkage happens from heat and rough handling. Here's how to avoid it:
-
Always use cold water under 85°F. Hot water shrinks wool fast.
-
Never rub or twist. Just swish gently.
-
Skip the dryer. Air dry flat every time.
-
Use wool-safe soap only. Regular soap makes fibers tight.
-
Soak for no longer than 10-15 minutes.

Reshape while damp. This locks in the size.
