Have you ever had the experience of washing your laundry with the smell of sweat and not being able to get the smell out? Sweat odor and sweat stains are difficult to remove with regular washing. So this time, we will introduce a washing method to remove those unpleasant sweat odors and sweat stains.
What causes sweaty clothing to smell?
Why does sweaty clothing become smelly in the first place? Here, we will explain what causes clothing to smell and the sweat stains caused by sweat.
Types of sweat and mechanisms of odor generation
There are two types of sweat: sweat from eccrine glands and sweat from apocrine glands, each with different properties and mechanisms.
Sweat from the eccrine glands
Sweat secreted by eccrine glands itself has no odor
. However, the sweat that comes out on the surface of the skin mixes with dirt such as sebum and dirt, and the bacteria that live on the skin decompose and oxidize it
, causing the sweat to smell
. Additionally, when the filtration function of sweat glands decreases, sweat contains more minerals such as sodium chloride, potassium, and amino acids, making it easier to produce a stronger odor.
Sweat from apocrine glands
Apocrine glands are sweat glands that are found in large numbers in the armpits and contain substances that give the skin a unique odor
, such as proteins, lipids, fatty acids, and cholesterol. This odor is sometimes called pheromones
, and if it is too strong, it becomes an unpleasant odor, and the symptom is called ``armpit odor.'' Although there are differences in the components contained in sweat produced by eccrine and apocrine glands, both types are exposed to bacteria from the moment they reach the skin, and decomposition and oxidation begin, producing odor. When this sweat gets on your clothes or towels, it is decomposed and oxidized by bacteria, which causes the clothes and towels themselves to smell.
Be careful of sweat stains over time! Care when changing clothes is important
Have you ever taken out last season's clothes and found that the neck and armpits have turned yellow
? It is the result of sweat and sebum stains that have not been properly removed and oxidizes
over time. Dirt that has penetrated deep into the fibers cannot be removed by a washing machine alone, so special care is important when changing clothes. Use the following method to properly remove sweat and sebum stains.
How to wash clothes to remove sweat odor and sweat stains
The smell of sweat and sweat stains on clothes cannot be removed simply by washing them normally. Here we will show you how to wash your clothes to remove all that dirt.
Why doesn't the smell of sweat go away even after washing?
There's a reason why sweat odor doesn't go away no matter how many times you wash your clothes. This is because the dirt has not been properly removed
. If even a small amount of sweat or sebum remains, bacteria feed on it and cause odor. First, let's review the following three things.
Amount of laundry input
If you put too much laundry in the washing machine, the detergent won't be distributed all over the place, so put 70 to 80% of the laundry into the washing machine.
Number of rinses
If cleaning solution remains on your clothes, bacteria may also remain, so it is important to rinse your clothes at least twice to ensure that the cleaning solution is thoroughly rinsed away.
Is it not half-dried?
Bacteria thrive in hot and humid environments, so hang your clothes to dry immediately after washing. Try using a circulator to dry your laundry faster.
Remove sweat odor with hot water and soak
If your laundry smells like sweat, soak it in hot water containing a detergent containing enzymes that break down proteins. By using hot water, sweat and sebum dirt that has penetrated deep into the fibers will be dissolved. The procedure is simple, so please incorporate it into your daily laundry routine.
Things to prepare
・Laundry detergent Rinenna (If you are concerned about odors, Rinenna #2 is recommended) ・Bucket
① Put the detergent in a bucket of hot water at about 40℃ and dissolve it thoroughly. ② Put the laundry in ① and let it soak for at least 30 minutes. ③ Put the soaked laundry in ② directly into the washing machine and wash as usual. Linenna, which has an exquisite combination of ingredients, is a special detergent that is popular for removing dirt just by leaving it on. Please see the product details from the link page below. Rinenna #2 is recommended for those who are particularly concerned about smells.
Strong against sweat odor! Pay attention to the latest features of washing machines
If you don't have time to soak your clothes, you can rely on the latest features of your washing machine. Please check out the lineup of models from each manufacturer that are equipped with convenient functions that allow you to reach those itchy areas. I would like to introduce two features that I particularly recommend.
Wash with hot water
Temperature settings vary from 30℃ to 60℃ depending on the manufacturer, but there are many models in the lineup that are equipped with a hot water washing function. It dissolves hot water and sebum stains, and maximizes the power of the enzymes contained in the detergent, so you can expect a good wash.
Add detergent twice
Some of the latest models even add detergent twice during washing! The more detergent you use, the more effective it will be at removing dirt, but what you need to be careful about is washing thoroughly. Models equipped with a double-add detergent function are a very logical and noteworthy feature as they also rinse thoroughly. This time we introduced stains such as sweat odor and sweat stains, and Linenna sells a soaking detergent that thoroughly removes such stains. There are two types of soaking detergent: ``Rinenna #1'', which can be used on colored items, and ``Rinenna #2'', which cleans white items to a pure white color, so why not take this opportunity to try them out?
