■ The causes of blood stains on tatami and the worst-case scenarios if left untreated
When blood stains get on tatami, it is not just a matter of appearance; leaving them untreated can worsen the condition and cause damage to the tatami itself. In this chapter, I will talk about why blood soaks into tatami, the effects of time passing, and actual repair cases.
・What is the mechanism by which blood soaks into tatami?
Tatami is made of rush grass, and its surface has countless tiny fibers and cavities. When these fibers absorb blood, the stain soaks deep into the interior.
Furthermore, because blood contains proteins and iron, it has the characteristic of oxidizing and hardening, making it harder to remove as time passes. Since tatami is a delicate material, once it has soaked in deeply, it is often not easy to remove.
・What happens as time passes? Explained from a professional perspective
Over time, the proteins in blood harden and become entangled in the fibers of the tatami mat. Furthermore, due to the effects of humidity and temperature, the stain can oxidize, causing it to darken or discolor into a brownish hue.
In actual situations, we often hear people say, 'No matter how much I clean it, it won't come out!' Once it reaches this state, it becomes difficult to handle with store-bought detergents or light wiping, and in some cases, the only option is to replace the tatami mat itself.
Additionally, while left untreated, the components of the blood can become nutrients for mold, causing it to spread. This leads to hygiene issues as well. Especially during humid seasons, leaving it untreated makes the tatami mat even more prone to damage, so caution is required.
・Actual case study of 'blood stain' restoration encountered
Previously, there was a case where blood was left on a tatami mat for several days. The family had inadvertently put off cleaning it, and the blood had dried, causing the stain to penetrate deeply.
In this case, even after cleaning the surface, the stain could not be completely removed, and ultimately, a partial replacement had to be performed.
In another instance, thanks to proper first aid immediately after the blood got on the mat, almost no stain remained.
This person immediately absorbed the blood with a dry cloth, attempted to wipe it with water, and then cleaned it using a neutral detergent. As a result, the stain was almost entirely removed, and they were able to avoid a replacement.
There are many episodes like this that make one keenly aware of how important early action is. Tatami mats are more delicate materials than they look, so acting immediately without leaving them untreated is the secret to keeping them clean!

■Initial response to avoid leaving blood stains on tatami mats untreated
To remove blood stains from tatami mats, early action is very important. In this chapter, we will explain simple first aid that can be done with household tools and points to keep in mind to avoid failure.
Incorrect methods can sometimes have the opposite effect, so let's make sure to grasp the correct initial response!
・How to perform first aid with a dry cloth and water
If blood gets on a tatami mat, first gently press it with a dry cloth or paper towel to absorb the blood.
The point here is not to rub it. Rubbing will cause the blood to penetrate further into the fibers, making it even harder to remove.
Next, gently dab the area with a cloth lightly dampened with water to wipe it away. This method can remove some of the surface blood. However, be careful not to get it too wet, as using too much water can damage the tatami or cause mold to grow.
・Why incorrect handling makes stains worse
When you find a blood stain, you might be tempted to scrub it hard, but this is a major pitfall. Scrubbing too much spreads the stain and can damage the tatami fibers.
Also, using strong detergents like bleach right away is a no-go. It risks discoloring the tatami or deteriorating the material.
For example, we had a client before who said, 'I tried bleach and the tatami turned white!' It is important to choose the right detergent and follow the instructions for use.
・How to choose cleaning items without failure, as taught by professionals
For cleaning blood stains, a neutral detergent is generally recommended. It removes dirt relatively gently. To use it, dilute it with water, soak a cloth in it, and gently dab the stained area. This will remove most light stains.
Always use it diluted. Using it undiluted can damage the tatami. It is also important to dry it thoroughly after cleaning. Since leaving moisture behind increases the risk of mold growth, ensure good ventilation to let it dry.
Just by taking the correct initial action, you can prevent the stain from spreading and protect the beauty of your tatami! Please use this as a reference.

・Can OxiClean be used on tatami? Explaining the precautions
OxiClean is also effective for blood stains, butcaution is required when using it on tatami.When using it, be sure to dilute it in a container first.
Specifically, dilute it to double the recommended volume, soak a cloth in it, and gently dab the stained area to see how it reacts.
If you do not feel it is effective, increase the concentration just a little bit. Just a little bit.
However, since OxiClean has a bleaching effect, it is essential to perform a test in an inconspicuous area. Depending on the color and texture of the tatami, it may become bleached, so do not neglect to check.
Also, it is important to thoroughly wipe off the detergent with a damp cloth after use. If detergent remains, it can cause the tatami to discolor or become damaged.

■ When blood stains cannot be removed / Professional methods performed on-site
If you have a blood stain on your tatami mat and it could not be removed with household cleaning, we will introduce specific methods that professionals use on-site. This is a last resort to make the stain less noticeable without damaging the tatami material.

Stain removal method using chalk
If the blood stain is stubborn, a method using chalk is effective. Use the side of the chalk to gently rub the stained area.
After that, just wipe it off lightly with a dry towel. Through this process, the stain will fade and often become almost unnoticeable to the eye.
However, this is a last resort and does not mean the stain has been completely removed chemically or physically.
It is merely a treatment to make it less noticeable. Please keep in mind that especially deeply soaked blood stains may become noticeable again over time.
Also, for new tatami or light-colored tatami, it is safer to try it on an inconspicuous area before using chalk. Since applying too much force can damage the tatami, the key is to work gently and carefully.
Replacement when stains cannot be removed
If the blood stain absolutely cannot be removed, we may perform a partial replacement of the tatami surface. In this work, only the stained part is replaced with a new tatami surface, so the appearance can be restored to look like new.
Previously, for a customer's tatami where a blood stain had been left for a long time, the dirt had spread over a wide area and could not be solved with first-aid measures. In this case, we proposed a partial replacement and were able to restore the beauty of the entire room.

■ How to deal with stubborn blood stains / Points for choosing a detergent
If blood stains have soaked deep into the tatami mat, household cleaning items may not be enough to remove them. In this chapter, we will explain how to choose a detergent suitable for stubborn blood stains and when to request professional help.
・How to avoid failure with commercial detergents
When using commercial detergents, the key is to choose a neutral detergent. Neutral detergents are less likely to damage the tatami and can be used with peace of mind.
Dampen a cloth with a neutral detergent diluted with water and clean the stained area by dabbing it lightly. At this time, scrubbing is strictly prohibited. It will cause the dirt to penetrate deeper into the fibers, making the stain even harder to remove.

・There is also the option of asking a cleaning professional / Getting a tatami replacement at a tatami shop is faster
If the blood stain is stubborn and cannot be removed with home cleaning or commercial detergents, you can also request a cleaning professional. However, the reality is that it is extremely difficult to completely remove stains from tatami mats where blood has soaked in for a long time.
Therefore, having a tatami shop perform a "tatami replacement" is the most reliable and fastest solution. Tatami replacement includes methods such as partially replacing the tatami surface or replacing the tatami mat itself with a new one.
Both methods can cleanly reset stains and dirt, and refresh the impression of the entire room.
In previous cases, tatami mats where blood stains had penetrated deeply and could not be handled by cleaning were replaced by a tatami shop, restoring the room to a brand-new beauty. By consulting with a professional at a tatami shop, they can propose the best plan tailored to the condition of your tatami.
Requesting a cleaning professional is one method, but replacing the tatami can sometimes be the best option for tatami mats you intend to use for a long time. If you are unsure, please consult your local tatami shop!

■ Preventive measures to know to avoid blood stains on tatami mats
If left untreated, blood stains will soak deep into the tatami, making them difficult to remove. Therefore, in this chapter, I will share specific methods for preventing stains through daily cleaning and maintenance.
・How to prevent stains with daily cleaning and maintenance
Daily cleaning is important to keep tatami mats clean. I recommend that my customers wipe them down once a week using tools specifically designed for tatami. Even just dry wiping can remove surface dirt and keep the tatami in good condition.
Also, laying down a carpet or rug is one way to protect tatami from dirt and stains.
This prevents liquids from soaking directly into the tatami if they are spilled. This is an especially effective measure for households with small children or pets. Choosing a washable type of carpet or rug makes maintenance easy as well.

・3 steps to take immediately when blood gets on the mat
Do not let the blood absorb: First, gently press the blood with a dry cloth or paper towel. At this time, be sure not to rub it.
Wipe the surface with water: Lightly dampen a cloth with water and wipe the stained area by dabbing it. Be careful with the amount of water used, as using too much can cause the tatami to become damp and damaged.
Let it dry: After the work is done, dry it thoroughly with a fan or air conditioner. Removing moisture prevents the growth of mold.
・"Habits for protecting tatami" that I practice
As a tatami craftsman myself, I share habits for keeping tatami clean on a daily basis with my customers.
For example, I ventilate the room sufficiently at the change of seasons so that the tatami does not absorb too much moisture. Also, if dirt gets on it, I perform first aid immediately to prevent the stain from soaking in deeply.
Furthermore, by laying down carpets or rugs, I incorporate ways to prevent daily dirt while keeping the beauty of the tatami for a long time. By incorporating these methods, you can maintain a comfortable space while keeping your tatami clean.
■ Summary of what to do to ensure blood stains do not remain on tatami
If blood gets on tatami, leaving it untreated can cause the stain to soak in deeply, making it difficult to remove. However, as I have explained in this article, if you take appropriate initial action and preventive measures, it is possible to make the stain less noticeable in many cases.
The most important thing is to "act immediately" once a stain occurs. By pressing with a dry cloth to absorb excess blood and then trying appropriate cleaning methods, you can significantly reduce the risk of a stain remaining.
When using items like neutral detergent, please do not forget to test it on an inconspicuous area first.
It is also important to incorporate habits to protect your tatami mats on a daily basis. By continuing preventive measures such as laying down carpets or rugs to prevent stains and cleaning regularly to keep the tatami clean, you can minimize damage when an emergency occurs.
If the stain still does not come out, the best choice is to consult a tatami shop and consider replacing the mats. By performing partial or full replacement, you can restore both the appearance and functionality to a beautiful state.
Tatami mats are an essential element of Japanese homes. I hope you will provide proper care and enjoy a comfortable Japanese-style room space while keeping them in a beautiful state for a long time!
