At what temperature should I wash underwear?

The right washing temperature for underwear depends primarily on the material, the level of soiling, and the wash label. In many cases, 40 degrees is a safe choice for everyday underwear, while delicate fabrics are more often washed at 30 degrees. For extra hygiene or sturdier items, 60 degrees may sometimes be suitable, but only if the label allows it.

If you want to keep your underwear clean and looking good, there is one basic rule that always applies: check the care instructions on the item itself first. You can find this information per item on the product pages of MyComfort24, so you can make the right choice faster.

The short answer: 30, 40 or 60 degrees?

There is no single temperature that is correct for all underwear. These are the most useful guidelines:

30 degrees - usually suitable for delicate fabrics and more sensitive underwear
40 degrees - often a good standard for everyday underwear
60 degrees - suitable for some sturdier items if extra hygiene is desired

Washing at a higher temperature is not automatically better. Washing too hot can degrade elastic, shape, and fabric more quickly. That is why the wash label is more important than a general rule of thumb.

Which temperature should you choose for each type of underwear?

Underwear at 30 degrees

30 degrees is usually the safest choice for sensitive or fine fabrics. Think of items where softness, elasticity, or shape retention are important. Underwear with careful wash instructions also often falls into this category.

A concrete example from the MyComfort24 range is a Calvin Klein women's thong with 30° gentle wash instructions.

Underwear at 40 degrees

For many people, 40 degrees is the practical middle ground. It is often warm enough for everyday underwear and at the same time gentler on the fabric than 60 degrees. This is a common recommendation, especially for many briefs and boxers.

An example is a Hom men's brief with 40° gentle wash instructions.

Underwear at 60 degrees

60 degrees can be useful if you want to wash with extra hygiene and the item is suitable for it. You sometimes see this with sturdier cotton or specific items. However, 60 degrees is not a good idea for every piece, because elastic fibers can wear out faster.

Underwear at 95 degrees

Some items may be washed exceptionally hot, but that is the exception rather than the rule. An example is a Mango men's brief 2-pack with 95° wash instructions. Never see such a temperature as standard advice for all underwear.

Is 40 degrees warm enough for underwear?

For much everyday underwear, 40 degrees is warm enough, especially if the item is normally soiled and the wash label indicates this temperature. It is often a good balance between washing clean and maintaining fit, color, and elasticity.

If you want to wash warmer for extra hygiene, only do so when the material and label allow it. When in doubt, it is better not to choose a higher temperature yourself. For period underwear, specific, lower washing instructions often apply; read Period underwear: what is it and how does it work?.

Why is 60 degrees often recommended?

60 degrees is often mentioned because it can be a hygienic choice for some types of underwear. This is especially relevant for sturdier materials or when you want to wash more thoroughly. But that guideline is too general if you do not take the fabric into account.

Much modern underwear contains elastic or finer fibers. In that case, 60 degrees may be too hot. That is why "washing underwear at 60 degrees" is only correct if the specific item is made for it, which is closely related to the insights from Textile types for underwear: which fabric suits you?.

Can you wash underpants and towels together?

That is sometimes possible, but only if color, temperature, and wash instructions match. In practice, that is not always ideal. Towels are often washed warmer than underwear, while much underwear needs a lower or gentle wash.

If you want to keep your underwear looking good for as long as possible, washing separately or sorting by temperature is usually the safest choice.

How to make the right choice without guessing

Always check the wash label - that remains the most important source
Look at the material - delicate fabrics usually require lower temperatures
Pay attention to elasticity - washing too hot can affect stretch and fit
Tailor to use - everyday underwear often requires something different from a specific or more sensitive item
Check the product page - at MyComfort24, the wash instructions are listed per item
