Why does sweat smell remain in clothes?
The sweat smell in clothes that comes back as soon as the garment is ironed or worn again is caused by butyric acid.
Everyone sweats during sports or just daily activities. As soon as the sweat dries, the so-called butyric acid, which is excreted by the body during perspiration, remains. The butyric acid continuously produces stench molecules and it is most active when the garment is warm. So when it is ironed or worn. If the butyric acid is not removed completely during washing, the sweat smell in clothes will return.
Sweat smell in clothes and other textiles can be caused by damp laundry that is left too long in the sports bag, laundry basket or in the washing machine.
3 tips to prevent sweat smells in clothes
Of course you would prefer to prevent sweat smells in your clothing. Be sure to clean your washing machine regularly so no bacteria remain. And we recommend the following if you sweat quickly and profusely.
1. Wash your armpits regularly
If you sweat profusely, we recommend washing your armpits at least once a day. This way you remove bacteria that cause the sweat smell and you prevent the smell of sweat getting in your clothes.
2. Only wear clothes 1 day
Do not wear your clothes more than one day and wash them more often. This prevents butyric acid from building up in your clothing. Deodorant is not an option when it comes to covering up sweat smells in clothes, because the deodorant will disappear from the clothes after time. And the sweat smell will only get worse.
3. Use antiperspirant
If you really have a problem with sweat smells in your clothes, we recommend using an antiperspirant deodorant instead of regular deodorant. Antiperspirants contain substances that inhibit the sweat glands so there will be less perspiration (and therefore less butyric acid) in your clothes.
2 tips on how to get sweat smell out of clothes
You can try vinegar and soda to remove sweat smell in textiles as well as prevent them.
Leave the garment to soak in soda and water for at least an hour and then wash it in the washing machine. The various websites do give some contradicting advice: some say “minimum one hour”, others say “overnight” in soda. In any case, be careful with coloured laundry as soda can cause discolouration. Soda will also damage silk and wool.
Do not let the smell of vinegar scare you! Soak your sweaty clothes in a bucket with vinegar before washing. Make sure the garment is completely submerged and let it soak for at least an hour (overnight is even better) and then wash it in the washing machine.
