How Often Should You Wash Your Aran Sweater?

Aran sweaters, with their rich heritage, intricate cable-knit designs, and luxurious wool fibers, are more than just warm garments—they’re timeless pieces of Irish craftsmanship. Whether hand-knit or machine-made, these sweaters are made to last, but only if properly cared for.

Unlike fast fashion or synthetic knits, Aran sweaters—often made from 100% wool or merino wool—require gentle handling to preserve their shape, texture, and longevity. One of the most common questions people ask is: How often should you wash an Aran sweater?

In this guide, you’ll learn how frequently to wash an Aran sweater, the best way to clean it, and how to store it properly so it remains a cherished part of your wardrobe for many years.

🧼 1. Washing Frequency: Less Is More

When it comes to washing your Aran sweater, the golden rule is don’t overwash. Wool is a naturally self-cleaning fiberwith properties that repel dirt, wick moisture, and neutralize odors.

How often should you wash an Aran sweater?

  • 1–2 times per season is typically sufficient.

  • Wash only when the sweater is visibly dirty or begins to develop an odor.

  • Frequent washing can weaken the wool fibers and lead to shrinkage or distortion of the knit pattern.

Pro Tip: If you wear your Aran sweater over a base layer or shirt, it will stay fresher for longer.

✨ 2. Spot Cleaning for Small Stains

If you spill a bit of coffee or food on your sweater, there’s no need to do a full wash. In fact, for most minor accidents, spot cleaning is the preferred method.

How to spot clean:

  • Use a damp cloth with a small amount of mild, wool-safe detergent.

  • Dab (don’t rub!) the stain gently to avoid damaging the wool or distorting the knit.

  • Let it air dry naturally, laying flat.

Avoid bleach, harsh detergents, or vigorous scrubbing, all of which can damage wool fibers.

🌬️ 3. Airing Out Your Sweater Between Wears

Wool is breathable and naturally resists odors, which means that simply airing out your sweater is often enough to refresh it between wears.

How to air out an Aran sweater:

  • Lay it flat on a clean towel or mesh drying rack.

  • Leave it in a cool, dry, and shaded place with good airflow.

  • Avoid hanging it, especially when damp, as this may stretch the shoulders and neckline.

Letting your sweater “breathe” after wear helps release trapped moisture and odors, keeping it fresh without needing a wash.

🫧 4. When and How to Hand Wash Your Aran Sweater

If your sweater needs a full clean, hand washing is the safest method. Never use a washing machine unless it has a dedicated wool cycle—and even then, proceed with caution.

Hand Washing Instructions:

  1. Fill a clean basin with cool or lukewarm water (never hot).

  2. Add a capful of wool-specific detergent or gentle baby shampoo.

  3. Submerge the sweater and gently swirl it around for 5–10 minutes.

  4. Do not wring or twist the sweater—this stretches and damages the fibers.

  5. Drain the soapy water and refill with clean water to rinse thoroughly.

  6. Repeat the rinse if needed until all detergent is gone.

Avoid agitation—gentle handling is key. Think of it like bathing a delicate fabric, not scrubbing clothes.

🧺 5. Drying: Always Lay Flat, Never Hang

After washing, how you dry your Aran sweater is just as important as how you wash it. Wool is heavy when wet, and improper drying can cause irreversible stretching.

How to dry it properly:

  • Lay the sweater flat on a clean, dry towel.

  • Gently roll the towel with the sweater inside to press out excess water (don’t wring it).

  • Place the sweater flat on a dry towel or mesh drying rack, reshape it carefully to its original form, and leave it to air dry naturally.

  • Keep it away from direct sunlight, radiators, or tumble dryers, which can shrink or distort the wool.

Drying Tip: Reshape the sweater by gently stretching it back to its original dimensions—pay attention to the sleeves, neckline, and hem.

📦 6. Storing Your Aran Sweater Correctly

When not in use—especially during warmer months—it’s important to store your Aran sweater properly to prevent mildew, moths, and deformation.

Wool storage best practices:

  • Fold your sweater neatly and store it in a cool, dry place.

  • Use a breathable cotton storage bag, fabric garment cover, or a drawer lined with acid-free tissue paper.

  • Avoid hanging wool garments long-term—gravity can stretch the knit.

  • Place lavender sachets or cedar blocks in your storage area to naturally deter moths without harsh chemicals.

  • Never store in sealed plastic bags, which trap moisture and lead to mustiness or mildew.

Bonus Tip: Always store your sweater clean, as body oils or stains can attract moths.

🧵 Additional Care Tips to Prolong the Life of Your Aran Sweater

  • Avoid friction: Repeated rubbing (e.g., from seat belts or backpacks) can lead to pilling or wear. Rotate how you wear and layer your sweater to reduce friction points.

  • Dealing with pills: If your sweater develops pills (tiny wool balls), gently remove them with a fabric comb or sweater stone—never pull them off by hand.

  • Read care labels: Every Aran sweater is different—especially hand-knit vs. machine-knit versions—so always follow the manufacturer’s specific care instructions.

🧡 Final Thoughts: Love Your Wool, and It Will Love You Back

Aran sweaters are more than just garments—they’re heritage pieces woven with tradition, meaning, and incredible craftsmanship. Proper care ensures that your Aran sweater retains its beauty, warmth, and fit season after season.

By washing it sparingly, handling it with care, and storing it correctly, you can extend the life of your sweater for decades to come. Whether it’s a treasured heirloom or a new addition to your wardrobe, your Aran sweater deserves the same thoughtful attention that went into making it.
