What causes clothes to turn yellow?
Clothes that have been washed before changing clothes.
Have you ever taken it out the next year and found that the neck, sleeves, and armpits were yellowed?
Stubborn yellowing is caused by dirt from sweat and sebum from the body.
Sweat and sebum stains are invisible to the naked eye, so it feels like they've come off cleanly after washing.
However, the protein stains contained in sweat are difficult to dissolve in water, so they cannot be removed simply by running them in the washing machine.
Sebum dirt that cannot be removed accumulates and oxidizes over time, resulting in yellowing.
Furthermore, if dust etc. adhere to the surface, the yellowing will turn into blackheads.
In this article, we will explain how to remove yellow stains from clothes and how to prevent yellow stains.
By taking good care of your favorite clothes, you can keep them looking good for a long time.
5 ways to remove yellow stains from clothes
For clothing that has already become yellowed and visibly soiled, we will perform special care to remove accumulated sebum stains.
Rinenna can remove stains without the need for massaging, but when massaging with an alternative detergent, be careful not to use too much pressure to avoid damaging the fibers of your clothing.
If you scrub it too hard with a brush, you may damage the fibers.
Always check the washing label before removing stains!
Please note that washing clothes that do not follow the clothing label may cause discoloration, shrinkage, or deterioration.
Items with a cross written on the tub indicate that they cannot be washed at home .
Consult with a cleaning shop.
The hand in the bucket is a sign to wash your hands .
There are some models that can be washed in a washing machine, such as those on the "delicate cycle," so check the instruction manual.
Before applying heat, check the number inside the "pail mark".
You cannot use hot water for clothes with a rating of 30.
The more lines under the tub, the more delicate the garment.
For items with two lines, it is best to avoid massaging them and wash them by hand.
There are some clothes that cannot be bleached.
Level 1: Dish detergent for light yellowing
Among the household items, kitchen detergent is a detergent that is resistant to oil stains.
Light stains can be removed by scrubbing with dish detergent.
Apply it to areas where you are concerned about dirt and massage.
Rinse thoroughly, being careful not to apply too much pressure and make sure no detergent ingredients remain on the clothes.
Level 2: For partial yellowing and deep yellowing, use oxygen bleach + steam.
If the stain is thick, make a paste by mixing kitchen detergent, oxygen bleach, and hot water at about 40℃ and apply it.
Then, by adding steam from the iron, the sebum stains that have soaked into the clothes will be dissolved.
Just as using hot water to wash oil-covered dishes removes stains better, applying heat can help remove sebum stains that accumulate deep within the fibers.
Level 3: Sesquicarbonate soda is also effective!
Sesquicarbonate soda does not use surfactants and is resistant to sebum and blood stains.
Spray on any areas where you are concerned about yellowing, massage lightly, and then put it in the washing machine.
If you are concerned about overall yellowing or darkening, dissolve it in water and leave it on.
Level 4: For general yellowing, soak in oxygen bleach.
If you want to easily remove stains, soaking it in bleach is also effective.
Dissolve oxygen bleach in hot water of about 40℃, let it sit for about 30 minutes, then put it in the washing machine.
If there are some areas that are extremely dirty, it is effective to apply liquid detergent, scrub the area, and then apply it.

POINT Difference between bleach and detergent Bleach and detergent, which have the image of removing stains from clothes, have different mechanisms. ■Bleach removes stains by destroying their pigments through a chemical reaction. Bleach is more effective at removing stains, but it also puts more stress on the fibers. |
Level 5: Wash white cotton clothes by boiling them with baking soda.
If you want to remove yellowing more mildly, boiling with baking soda is also effective.
Add baking soda and clothes to an unused pot and boil to wash.
By boiling and washing, the sebum that has penetrated deep into the fibers dissolves and eliminates the unpleasant odor that has accumulated.
When washing by boiling, be sure to check the washing label and be careful not to get burned.

You can remove sebum stains more effectively by washing with warm water in the washing machine after soaking.
Even if your washing machine does not have a hot water washing function, you can easily wash your clothes in hot water by using a hot water hose.
Warm water washing is effective not only for yellowing clothes, but also for preventing yellowing after sweating.
Does bleach work on yellowing clothes?
Bleach is also effective when you want to easily remove stains.
However, unlike detergents that remove dirt by lifting it from the fibers, bleach chemically breaks down the pigment and dirt, so it may damage the fibers in the process of removing the dirt.
It is important to use them appropriately depending on the fiber material and degree of dirt.
*Chlorine bleach has very strong bleaching power, but it can only be used on white items.

How to prevent yellowing of clothes
Once every three months, check for yellowing when changing clothes.
Yellowing of clothes is caused by unwashed sebum stains .
To prevent yellowing, it is important to wash thoroughly without leaving any sebum stains when washing.
In particular, before changing clothes, it is essential to wash them thoroughly and take care to avoid leaving stains on them.
Take good care of your favorite clothes so you can wear them beautifully next year.
Soak and warm water wash before changing clothes
For white or light-colored clothing, or your favorite clothing, we recommend soaking and washing them before changing clothes .
Washing clothes soaked with bleach can be very taxing on the clothes, so if there are no visible stains, we recommend washing them soaked with alkaline detergent or Rinenna.
However, it is a lot of effort to soak and wash all the clothes for the whole family.
In such a case, wash it in warm water in the washing machine .
Washing with warm water dissolves sebum and dirt, removing odors and dirt.
(A simple method for washing with warm water is introduced above.)
Spot wash before washing
Wash sweaty clothing as soon as possible.
For collars and sleeves that tend to yellow, we recommend spot-washing them before washing, or applying liquid detergent before putting them in the washing machine.
You can also prevent yellowing of your laundry!
Review your usual washing methods
Yellowing is caused by the accumulation of sebum dirt, so it is necessary to take measures to prevent the accumulation of sebum as much as possible during regular washing.
Alkaline detergent to prevent yellowing of laundry
Especially during the summer, we recommend using an alkaline detergent that is resistant to sebum stains.
Powder detergent has higher cleaning power than liquid detergent.
However, alkaline detergents cannot be used on animal fibers such as wool.
*Although neutral detergent can be used on animal fibers, it will also be milder in removing stains.
Be careful not to pack too much clothing
Limit the amount of clothes you put into the washing machine to about 80% .
If you pack too many clothes, the clothes won't spin in the washing tub and won't be able to be washed properly.
When you have a large amount of laundry to do, set it to "high water level."
In particular, in the case of drum-type washing machines that use a small amount of water to wash clothes, it is recommended to wash the clothes at a rate of about 50% in order to thoroughly wash dirty clothes.
Thoroughly remove dirt by rinsing twice or more
It is no exaggeration to say that rinsing is the most important step in thoroughly removing stains and odors from clothing.
Clothes are soaked in contaminated water in the washing tub.
By rinsing thoroughly, you can wash your clothes cleanly without leaving any bacteria, sebum, or dirt on them.
Nowadays, there are detergents that only require 0 or 1 rinse, but even if you use them, be sure to rinse at least 2 times .
For those who are troubled by the smell and dark spots on their clothes, simply rinsing them more often can dramatically improve the appearance!
Be careful of humid storage locations!
Storing clothes in a humid place makes it easier for bacteria and mold to grow.
When storing your clothes, we recommend wooden chests with high moisture absorption or airtight plastic cases.
Wipe your sweat frequently and change your clothes if you are sweating
It goes without saying, but if you sweat, change your clothes as soon as possible.
It is also important to wear underwear to prevent sweat stains on your clothes.
By absorbing sweat from your body, your underwear will prevent sweat from staining your clothes.
When it's hot, wear proper underwear to prevent your skin from coming into direct contact with your clothes.
It's best to wash sweaty clothes immediately, but if you can't wash them right away, don't just put them in the laundry basket, but instead hang them out to dry as much as possible.
