How to Care for Your Aran Sweater

An Aran sweater is more than just a piece of clothing—it’s a timeless garment steeped in Irish heritage and renowned for its exceptional warmth, durability, and craftsmanship. When properly cared for, a high-quality Aran sweater can last for decades, retaining its beauty and functionality and often becoming a cherished heirloom. This guide offers detailed advice on how to care for your Aran sweater to ensure it remains a treasured wardrobe staple for years to come.

1. Understanding the Material

Aran sweaters are traditionally crafted from 100% pure wool, often sourced from sheep raised in Ireland. Wool is a natural, breathable fibre with excellent insulation and moisture-wicking properties, making it ideal for cold-weather garments. However, wool’s unique characteristics also mean it requires special care to maintain its shape, softness, and longevity.

One of wool’s many advantages is that it resists odours and repels dirt naturally, so frequent washing is unnecessary. In most cases, simply airing your sweater after wear is sufficient to keep it fresh.

2. Washing Your Aran Sweater

Wool is delicate and can become damaged if exposed to harsh washing conditions. To preserve the integrity of your Aran sweater, avoid machine washing or tumble drying. Instead, follow this gentle handwashing routine:

Materials Needed:

  • Mild wool detergent or gentle pH-neutral soap

  • Cold or lukewarm water (no warmer than 30°C / 86°F)

  • Clean towels

Step-by-Step Instructions:

1. Prepare the Wash Basin
Fill a clean basin or sink with cold or lukewarm water and add a small amount of wool detergent. Stir gently to distribute the soap.

2. Submerge the Sweater
Turn your sweater inside out and place it in the water. Gently press it down to fully submerge without wringing or stretching the fibres.

3. Soak and Clean
Let the sweater soak for 10–15 minutes. Gently swish it through the water to loosen dirt—do not rub or agitate forcefully.

4. Rinse Thoroughly
Drain the basin and refill it with clean water. Rinse the sweater by pressing gently. Repeat the rinse process until the water runs clear.

5. Remove Excess Water
Carefully press the sweater against the basin’s side to release excess water. Never twist or wring wool, as it can damage the fibres and distort the shape.

6. Dry Flat
Lay the sweater flat on a clean towel. Roll the towel to absorb remaining moisture, then unroll and reshape the sweater to its original dimensions. Lay it flat on a dry surface away from direct heat or sunlight.

Tip: Never hang a wet Aran sweater, as the weight of the damp wool can cause it to stretch and lose its shape.

3. Storing Your Aran Sweater

Proper storage plays a vital role in maintaining your sweater’s structure and protecting it from damage.

Short-Term Storage:

  • Always fold your sweater rather than hanging it.

  • Store in a cool, dry area away from direct sunlight or dampness.

Long-Term Storage:

  • Ensure the sweater is clean and completely dry before storing for the season.

  • Use breathable cotton storage bags to allow airflow while protecting from dust.

  • Add natural moth repellents like cedar blocks or lavender sachets to deter pests without chemicals.

4. Handling Stains and Spills

Accidental spills happen, but prompt, gentle treatment can prevent permanent staining.

For Fresh Stains:

  • Blot gently with a clean cloth to absorb excess liquid—avoid rubbing.

  • For oily or sticky stains, apply cold water and gently blot again.

For Set Stains:

  • Use a wool-safe stain remover.

  • Test the solution on an inconspicuous area first.

  • Apply to the stain, let sit briefly, and rinse gently with cold water.

Patience is key—never scrub or use hot water, which can set the stain or damage the fibres.

5. Dealing with Pilling

Pilling—those small wool balls that form with friction—is a normal part of wearing natural wool garments. It typically occurs in high-contact areas such as under the arms or around the sides.

To Remove Pills:

  • Use a wool comb or fabric shaver designed for knitwear.

  • Glide gently over the surface to lift and remove pills.

  • Avoid pulling pills by hand, which can snag or tear the fabric.

Regular maintenance helps your sweater stay smooth, soft, and looking like new.

6. Refreshing Your Aran Sweater Between Washes

There’s often no need to wash a wool sweater after every wear. Instead, use these techniques to keep it fresh between cleanings:

  • Air It Out: Hang in a well-ventilated area for a few hours to release odours and moisture.

  • Steam Lightly: Use a handheld steamer on a low setting to release wrinkles and revive the fibres.

  • Avoid Ironing: If needed, steam rather than iron—direct heat can flatten and damage wool’s natural crimp.

7. Repairing Minor Damage

Wool is resilient, but minor snags or holes can happen. Prompt repair keeps small issues from turning into permanent damage.

Snags:

  • Use a blunt crochet hook or needle to gently pull the snag to the inside of the sweater.

  • Do not cut the loose yarn.

Holes:

  • For small holes, use a matching wool thread and darning needle to stitch over the gap.

  • For larger or complex damage, consider seeking professional repair to preserve the integrity of the knit.

8. Seasonal Care Routine

Keeping your Aran sweater in excellent condition throughout the year requires a simple seasonal approach.

Spring/Summer:

  • Wash and dry thoroughly before long-term storage.

  • Place in a breathable bag with natural moth deterrents.

  • Store in a cool, dark place to prevent sun damage and fading.

Autumn/Winter:

  • Air out between wears to keep fresh.

  • Spot-clean as needed.

  • Inspect periodically for pilling or minor repairs.

This routine will extend the life of your sweater while ensuring it’s ready for wear every season.

9. Investing in Longevity

A high-quality Aran sweater is more than a garment—it’s a piece of living history. Every stitch carries the legacy of Irish craftsmanship, and with the proper care, your sweater can be enjoyed for decades.

By following these care tips, you not only preserve the shape, softness, and beauty of your sweater, but also honour the tradition and skill that went into creating it. With a little effort and attention, your Aran sweater will continue to provide comfort, warmth, and timeless style for generations to come.
