How to Clean Second-Hand Clothes: A Guide to Refreshing Pre-Loved Fashion

Buying second-hand clothes is a great way to save money, support sustainability, and find unique pieces that tell their own story. However, when it comes to second-hand fashion, ensuring that the items are clean and fresh before wearing is essential. Whether you’re buying clothes from thrift stores, second-hand shops, or online marketplaces like SwapUp, learning how to clean second-hand clothes properly is key to maintaining their quality and hygiene.

Here’s a comprehensive guide on how to clean second-hand clothes to ensure they’re ready to wear.

1. Check the Label for Care Instructions

Before jumping into cleaning, always check the garment’s care label for instructions. The label will provide important details on how to best wash and care for the fabric. Follow these directions to avoid damaging the clothing. If the label is missing or unreadable, refer to the fabric type (e.g., cotton, wool, synthetic) and research the general care instructions for that material.

Pro Tip: If the garment lacks a care label, do a patch test by washing a small area with mild detergent to check if the fabric shrinks or fades before washing the whole piece.

2. Inspect the Garment for Stains or Damage

Examine the second-hand clothes thoroughly for any stains, dirt, or damages. Look for:

  • Visible stains: Common ones include food, makeup, or deodorant marks.

  • Fabric wear: Check for holes, loose threads, or fading.

For stains, treat them with a stain remover before washing. Gently blot the stain (don’t rub) with the cleaner and a soft cloth. For damaged areas, consider mending or taking the garment to a tailor.

Pro Tip: For tough stains like ink or grease, apply a paste made from baking soda and water to the stain and let it sit for 15 minutes before washing. This helps break down the stain without damaging the fabric.

3. Wash with a Gentle Cycle

Once you've checked the garment and treated stains, wash it using a gentle cycle. A cold water wash is typically best for most second-hand clothes as it helps preserve fabric and prevents shrinking. Use a mild, eco-friendly detergent to avoid harsh chemicals that may damage the fabric.

If the garment is delicate (like silk or wool), consider handwashing it. For items with heavier stains, pre-soaking in a solution of water and detergent for a short period can help lift dirt before you wash them.

Pro Tip: Always separate your clothes by colour before washing. Dark clothes should be washed separately to avoid colour transfer to lighter fabrics.

4. Use Fabric Softener (Optional)

Adding a fabric softener to the wash can help soften the fabric and make it feel fresher. This step is especially beneficial for second-hand clothes that may have lost some of their original softness due to prior washing. Choose a natural fabric softener to keep the garment’s fibres intact.

Pro Tip: If you want a more eco-friendly option, add half a cup of white vinegar to the rinse cycle as a natural fabric softener. It helps break down detergent residue and freshens up clothes.

5. Dry Properly

Drying second-hand clothes requires care to avoid shrinking or damage. Air-drying is the safest option for most garments. Hang clothes on a clothesline or drying rack, out of direct sunlight to prevent fading. For delicate items, lay them flat on a clean towel to dry.

If you must use a tumble dryer, use the lowest heat setting to prevent shrinking or warping. Avoid overdrying, as this can weaken the fabric over time.

Pro Tip: Use a mesh bag when drying delicate items in a tumble dryer to protect them from damage caused by the dryer drum. Always remove clothes from the dryer promptly to prevent wrinkles.

6. Freshen Up with a Steam

For garments that are particularly wrinkled, use a steam iron to refresh the fabric and remove any lingering smells. Steam can also help to kill bacteria that may have been present on second-hand clothes, ensuring that your items feel fresh and new again.

Pro Tip: If you don’t have an iron, you can hang clothes in the bathroom while taking a hot shower. The steam will help release wrinkles naturally.

7. Check for Odours

Sometimes, second-hand clothes may have a musty or old smell. To tackle this, wash the clothes with a cup of white vinegar added to the rinse cycle. Vinegar naturally neutralises odours and works as a fabric softener too. If the smell persists, consider using a fabric refresher spray or repeating the washing process.

Pro Tip: If your clothes have a persistent smell, try leaving them outside for a few hours to air out in fresh air. This can help remove any remaining odours without the need for additional washing.

8. Maintain the Garment's Quality

Once your second-hand clothes are cleaned, it’s important to care for them properly to ensure their longevity. Regularly wash them only when necessary, and store them in a cool, dry place to avoid mould or mildew build-up.

For items that need extra attention, consider dry cleaning or professional laundering to preserve their quality over time.

Pro Tip: Store your second-hand clothes in fabric garment bags or cotton storage bags, rather than plastic, to prevent moisture buildup and allow the fabric to breathe.

Pro Tips for Cleaning Second-Hand Clothes

  • Test for Colourfastness: Before washing a second-hand garment, especially if it’s brightly coloured, test a small, inconspicuous area with water and detergent to check for colour bleeding.

  • Use a Mesh Laundry Bag for Delicates: To protect delicate fabrics, such as lace or silk, place them inside a mesh laundry bag before washing. This reduces the risk of snagging or stretching.

  • Pre-Treat Stubborn Stains: For tough stains like ink, grease, or wine, use a specialised stain remover or a DIY solution (like baking soda and vinegar) before washing. Let it sit for 15-30 minutes before washing.

  • Refresh Between Washes: If your second-hand clothes aren’t dirty but just need a refresh, spritz them with a fabric refresher spray or hang them outside in fresh air to remove lingering smells.

  • Avoid Over-Washing: Washing clothes too frequently can damage the fabric and fade the colour. Only wash your second-hand clothes when necessary, and opt for spot cleaning when possible.

  • Sanitize with Tea Tree Oil: If you're concerned about germs or bacteria, add a few drops of tea tree oil to your wash or soak the garment in a tea tree oil solution. This natural disinfectant can help eliminate bacteria and odours.
