Washing your underwear might seem simple. You toss them in the machine, press a button, and voilà—clean! But in reality, between stretched-out elastics, colors fading to a dull gray, and fibers breaking down at an alarming rate, your underwear often emerges from the wash tired and misshapen.
To avoid this textile disaster, here are some tips for washing your underwear without putting them through the wringer. And while we're at it, let's do it right: respecting the fabrics, our skin, and even the planet.
What temperature should you wash your underwear at?
Fun fact: a study found that washing at 30°C instead of 40°C uses 38% less energy. If everyone made this switch, the UK could cut its carbon footprint by an amount equivalent to taking 400,000 cars off the road. That's more than the annual CO₂ emissions of Manchester. Intrigued? Let's dive in...
Why opt for low-temperature washes?
Old habits die hard: no, you don't need to wash your underwear at 60°C (unless there's a particularly vengeful virus involved, but that's another story).
Here are three good reasons to wash your underwear at 30°C:
- High temperatures damage fibers, especially those containing elastane.
- Washes at 30 or 40°C are more than enough to eliminate bacteria and bad odors.
- Less heat = less energy consumption. Washing at 30°C uses about 40% less energy than washing at 60°C. Good news for your electricity bill!
| Wash Temperature | Drying Method | Carbon Footprint (kg CO₂e) |
|---|---|---|
| 30°C | Air drying | 0.6 |
| 40°C | Air drying | 0.7 |
| 40°C | Tumble dryer | 2.4 |
| 60°C | Washer-dryer | 3.3 |
The effectiveness of cold washes with modern detergents
Today's detergents are little chemical marvels. Designed to work well even at 30°C, they get the job done without needing high temperatures.
Some tips for an optimal wash:
- Use a suitable detergent (avoid those packed with overly aggressive enzymes).
- Don't overload the machine: water and detergent need to circulate properly.
- Select a quick wash cycle to maximize energy savings. More on this below.
What program and products should you use to wash underwear in the machine?
Choosing the right wash program
Your washing machine probably has a "lingerie" or "delicate fabrics" setting. It’s not just a gimmick:
- These programs use gentler spins to maintain elasticity.
- They reduce friction, helping your underwear keep its shape longer.
- If you don’t have this setting, a classic 30°C cycle with reduced spin (800 rpm max) will do the trick.
Another tip: avoid washing underwear with rough clothing (goodbye, abrasive jeans) and always separate colors to avoid mishaps.
Choosing the right detergent and cleaning products
A good wash also depends on choosing the right detergent. Avoid harsh ones to prevent premature fiber wear. As for fabric softeners—skip them. They reduce elasticity and leave a film on the fabric. And beware of using too much detergent; it can leave residues on underwear if not properly rinsed.
The ideal solution? Liquid detergent, which is gentler on fabrics than powder. If you're concerned about hygiene, a bit of white vinegar in the rinse cycle can help eliminate bad odors without compromising elasticity. And for the most delicate pieces, hand washing remains the best option.
Drying and care: Best practices to preserve your underwear
Why avoid the tumble dryer?
The tumble dryer is convenient... but it's also the fastest way to ruin your underwear. Excessive heat breaks elastic fibers and causes fabrics to shrink. If you want your boxers and briefs to last, it's best to avoid it.
Instead, opt for air drying, ideally in the shade (direct sunlight can damage colors). And if you do use a dryer, know that BLUEBUCK's waistband will likely withstand better than most other brands thanks to its high quality.
Tips for lasting care
Good care doesn't stop at washing. To keep your underwear in top shape, store them neatly instead of crumpling them in a drawer. Finally, always take the time to check labels before washing, especially for delicate materials like Tencel.
How often should you wash your underwear?
Regular washing is essential to prevent bacteria build-up and ensure good hygiene. Generally, underwear should be washed after each use. Wearing a boxer or brief for several days in a row is not an option: beyond bad odors, it can lead to skin irritation and infections. The same rule applies to socks, while pajamas and nightwear can be washed every two to three days depending on perspiration and the season.

Washing your underwear is a delicate art. Too hot, they shrink. Too much detergent, they wear out faster. Incorrect spin, they lose their shape. A little attention and the right habits can keep your underwear clean, comfortable, and in good condition for longer.
Plus, by adopting these practices, you use less energy and save on wardrobe renewals—good news for both the environment and your wallet.
