The Inside-Out Method

Washing machines clean using a combination of water, detergent, and agitation — essentially, fabrics rub against one another to lift away bacteria and debris. The problem is that many of us throw our socks and underwear into the washing machine right side out, keeping the bacteria tucked away in areas that are harder to reach.

To get the most out of that scrubbing power, always ensure the dirtiest side of your clothing faces outward. In the case of socks and underwear, this means turning them inside out. Doing so exposes the surfaces that come into contact with your skin, allowing the detergent and water to better wash away the sweat and bacteria accumulated during wear.

With socks, for example, the coarser material inside easily traps debris such as dead skin and lint. Flipping that part outward allows the machine’s friction to dislodge those microscopic particles. As a bonus, it also protects the outer fibers from pilling and fading.

To make this easier, reverse your undergarments when you take them off and before throwing them into the hamper. That way, when laundry day comes around, you won’t have to worry about an extra step — your socks and underwear will already be inside out and ready to be cleaned.

A Good Wash vs. a Great Wash

This isn’t to say that your socks and underwear won’t get clean if you leave them right side out. It’s just that you can achieve a much more effective, hygienic clean with this one simple hack. Give it a try on your next laundry day — we think you’ll be happy with the results.
