What To Do With Old Underwear & Socks?

We all have a bunch of used underwear with worn-out elastic straps, holes, and discolorations piling up somewhere in our closets or underwear drawer. Your underwear is such a personal item, and giving it out like you would a pair of jeans is not an option. 

Dumping your old undies in the trash might be the easy way out. However, doing this will contribute significantly to textile waste, a primary plague in the fashion industry. Textile waste materials can take many years to break down entirely in landfills. 

So what do you do when your old panties or briefs begin to slack, and the old bras fall apart?

Read on as we look at sustainable ways to get rid of your old underwear.

• Use as plant holders: You can use the elastic or rubber band around your underwear to hold up your droopy plants. 
• Use for pillow stuffing: You can cut up your old undies into small pieces and stuff them in your pillow. Of course, you want to make sure that they are clean. 
• Use to make dog toys: Your furry ones can do with some sustainable toys, and your old underwear is just the right fabric to do it. Simply cut up your underwear, braid it, and knot it with a tight rope, and finally, your dog has a new toy to play with. 
• Use as reusable menstrual pads: Reusable menstrual pads are a great way to go green! You can cut up your clean undies and make a menstrual pad using a needle, thread, or even a sewing machine. Once your menstrual pad is used, you can wash it thoroughly and reuse them. 
• Use as a wash rag: If you have some clean old underwear, you can turn them into cleaning rags. Simply use your cleaning rags with your preferred cleaning product and wipe those dirty surfaces. 
• Use as a scrubber: You can cut your underwear into strips, put them in a porous bag made of strong material or plastic, and use them as a scrubbing sponge.

How to make your underwear last longer 

Using your underwear for longer will ensure you don’t replace them too often, reducing textile waste and protecting the planet. So how can we wear underwear to ensure they last longer? Here are a few simple care tips: 

• Invest in high-quality and sustainable underwear: Firstly, to wear your underwear for longer, invest in high-quality sustainable underwear made of sustainable fabrics like hemp. Though they may be more expensive, they will save you more money in the long run. With durable fabric, your underwear can withstand multiple washes without slacking off easily. If you’re the boxer type, check out our bamboo boxer shorts and ethical boxer shorts options. 
• Wash your undies separately: It can get tempting just to wash your underwear with the rest of your clothes. But washing your underwear separately can improve its longevity. If you wash your undies together, consider a lingerie bag. 
• Wash your underwear gently: One of the best ways to ensure your undies last longer is to wash them gently by hand using cold water. You want to scrub gently and avoid stretching them, no matter how stubborn the stains are. You can also use a washing machine on a gentle cycle, especially if you have a bunch of cotton undies. Lingeries are even more fragile, so you also want to be gentle with them. 
• Use an eco-friendly detergent: You can consider eco-friendly laundry detergents, or soap nuts, as they contain gentle ingredients that keep your underwear intact and free of stains and bacteria. 
• Air dry your underwear: Most undies suggest hand washing and air drying. To ensure your undies last longer, skip the dryers and simply hang them out in the sun. This is an excellent way to ensure they last longer and also a great way to kill any germs lurking underneath your garments. 

Does Goodwill take underwear?

Unfortunately, many traditional thrift stores like Goodwill and Salvation Army do not accept underwear donations, bras, or socks.

However, Goodwill will take underwear that is not used and is in perfect condition. Goodwill organizations collect and sell new or gently used items and use the revenue to provide employment training for people within the community. 

Final thoughts: What to do with old underwear 

Sustainable fashion is also about how we dispose of clothing, including underwear. Dumping your undies in the trash can will only compound the waste in landfills. Thankfully, as we have mentioned above, there are other sustainable ways to get rid of your old underwear.
