summary

一、スーツケースにつきやすい汚れの種類と原因

Title

Although we generally refer to stains on suitcases, the method of removing them varies depending on the cause and type of stain .
The first step in proper care is to know what types of dirt are likely to get on your furniture.

黒ずみ・擦れ跡

The most common type of stain is caused by scuff marks on airport conveyor belts, stairs, car trunks, etc.
It often leaves behind dark lines or gray marks, which are particularly noticeable on polycarbonate and aluminum surfaces .
This is caused by friction with other suitcases or metal parts, which can lead to color transfer of rubber or resin .
If it is a light stain, it can be easily removed with a cloth and diluted neutral detergent .

手あか・皮脂汚れ

The slight dark spots and shine that remain on the handles and sides are caused by sebum and oil from your hands .
This builds up gradually as you use the product, so you can prevent this by wiping it regularly with disinfectant wipes or alcohol spray .
Be especially careful with light-colored suitcases such as white or beige, as this type of stain is more noticeable.

泥・雨汚れ

Moving it on a rainy day or placing it directly on the ground can be surprisingly troublesome, as it can get muddy and stained.
If this dirt is left unattended, it will turn into black spots or ring stains over time.
When you return from being out, the basic rule is to wipe off any moisture with a dry cloth and lightly polish with a soft cloth .
Storing it in a damp state can cause mold and discoloration.

カビ・臭い

For suitcases that have been stored in a closet or cupboard for a long period of time,

White mold and uneven color may occur.
Since moisture is the cause, it is important to dry the inside before storing and store it in a well-ventilated place .
If mold occurs, spray with alcohol and gently wipe the surface with a soft cloth .

二、スーツケース掃除の前に準備するものと注意点

Title

Cleaning your suitcase is something you can do whenever you feel like it, but
In fact, a little preparation and the choice of tools can make a big difference in the final result.
If you wipe it the wrong way, you could damage the material or lose its luster.
First, get some basic cleaning items that are safe to use on any material .

基本のお掃除セット

The following tools will help you clean most suitcases:
All of these items can be found at drugstores and 100 yen shops.

掃除前に確認すること

Before you start cleaning, make sure you check the following:

🧳Check the material: "Polycarbonate," "Aluminum alloy," "Polycarbonate + ABS," etc.
By checking this, you can avoid using detergents and tools that should not be used.

💧Don't get it too wet. Fabric and leather materials in particular are prone to absorbing moisture, which can lead to mold.
Just wipe it gently with a damp cloth.

🌬️Work in a well-ventilated area. If you use detergent or alcohol, open a window to ventilate.
In small spaces, a strong odor tends to linger.

🧤When you wear gloves◎
Not only does it prevent rough hands, it also makes it less prone to fingerprints and gives a cleaner finish.

やってはいけない掃除方法

Don't use too much force, thinking that "rubbing hard will make it clean."

In particular, the following actions may damage the surface of the suitcase.

❌ Use abrasive cleaners. Glossy polycarbonate and aluminum materials are prone to fine scratches caused by abrasives.

❌ Wipe with hot water or dry with a hair dryer. High temperatures can cause deformation and deterioration of the adhesive. Air drying is the best way to go.

❌ Using bleach directly on fabric suitcases can cause discoloration and fiber damage.

三、【素材別】スーツケースの汚れを落とす方法

Title

Even if suitcases look similar, the way they get dirty and how to clean them varies greatly depending on the material.
If not properly cared for, it may lose its luster or the surface may become cloudy.
Here we will introduce how to gently and reliably clean four commonly used materials.

ポリカーボネート・ABS製スーツケース

Aluminum suitcases , such as those made by Rimowa, have a luxurious feel and their appeal lies in the fact that they develop a unique character the more you use them.
However, it is also a material that is prone to showing scratches and dullness due to oxidation.

▼ Care instructions:

① First, remove all dust with a dry, soft cloth .

② Gently wipe the stained area with a cloth soaked in diluted neutral detergent .

③ Finish by wiping dry to remove any remaining moisture.

④ If you are concerned about dullness or small scratches, lightly polish it with aluminum polish (contains abrasives).

point:

-Don't rub hard, imagine it as a gentle stroke.

- To maintain the shine, we recommend applying a thin layer of anti-rust spray or wax at the end.

🪞One way to enjoy the cloudy aluminum is to enjoy it as a flavor.

Rather than trying to make it shine like new, take care of it with the intention of developing a unique texture.

アルミ製スーツケース

Currently, the most common materials are polycarbonate and ABS plastic .
Although it is characterized by its smooth luster, it is also a material that is prone to scuffing and staining.

▼ Care instructions:

1. Wipe the entire surface with a soft cloth and a mild detergent diluted with water.

②To remove dark spots and rubber marks, use a melamine sponge and gently rub them away.

③ Finally, wipe off all moisture with a dry cloth.

point:

-Melamine sponges have a strong abrasive effect, so use light pressure and for short periods of time on shiny areas .

- Using an anti-static spray as a finishing touch will make it less likely to attract dust.

✨We also recommend using an eraser to remove light stains. Minor scratches will be restored to like-new condition in just a few seconds.

布製スーツケース

Soft and lightweight cloth suitcases are popular for casual travel and business trips,
It has the disadvantage that dirt and stains can easily penetrate deep into the fibers .

▼ Care instructions:

① First, remove any dust or sand from the surface using a vacuum cleaner or brush.

② Lightly press a cloth soaked in diluted neutral detergent onto the stained area to lift the dirt.

3) Wipe off the detergent with a clean, damp cloth and dry thoroughly.

④After it dries, spray it with a waterproof spray to prevent stains.

point:

-The basic rule is to press and absorb without rubbing.

- Leaving it wet can cause mold , so dry it in the shade in a well-ventilated area.

🌤️When you accidentally get muddy while traveling,

Lightly pressing it with a wet tissue will make cleaning easier when you get home.

四、落ちにくい黒ずみ・擦れ跡への対処方法

Title

For stubborn stains that won't come off with regular cleaning, try the following methods.

However, please understand that they may not disappear completely.

表面の黒ずみ

・Gently rub with an eraser
Gently rub the darkened areas with a plastic-specific eraser (a white eraser).

Be careful not to apply too much pressure.

 

・Use a melamine sponge
Wet a melamine sponge (such as "Gekiochi-kun") with water and gently rub the area.

However, this method is not suitable for matte-finish suitcases, so test it on an inconspicuous area first.

タイヤ跡・空港で付いた擦れ跡

・Wipe directly with neutral detergent
Apply neutral detergent directly to a sponge and gently rub the scuff marks. Then, wipe off the detergent with a wet cloth.

完全に消えない場合もある

Suitcases are subjected to impacts in various places during travel,

so deeply embedded dirt and scratches may not completely disappear.

 

In such cases, it's an option to accept them as "memories of your journey."

Additionally, using a suitcase cover can prevent future dirt and damage.

五、掃除後の保管方法とスーツケースを長持ちさせるコツ

Title

After cleaning, storing your suitcase correctly will help extend its lifespan.

保管前の準備

① Dry Completely

Storing a wet suitcase can lead to mold and odors.

Ensure both the interior and exterior are completely dry in a well-ventilated area.

 

② Clean the Casters

Remove dirt from around the casters and check if they move smoothly.

If movement is stiff, using a specialized lubricant can improve it.

 

③ Remove Interior Moisture

Placing a desiccant inside the suitcase can prevent mold and odors.

スーツケースを長持ちさせる方法

① Use a cover

Using a suitcase cover during travel or storage can prevent scratches and dirt.

Using a cover is especially recommended for light-colored suitcases.

New Trip offers waterproof covers for S/M/L sizes.

 

② Avoid direct sunlight

Storing your suitcase in direct sunlight for long periods can cause discoloration and deterioration.

Store it in a cool, well-ventilated place such as a closet or cupboard.

 

③ Check regularly

Even if you don't use it for a long time, take it out every 3 to 6 months to check for mold or odors.

六、よくある質問（FAQ）

Title
Q1. スーツケースの黒ずみは消えますか？

A1：表面的な黒ずみは、中性洗剤や消しゴムで落とせる場合が多いです。ただし、深く染み込んだ汚れや傷は完全に消えないこともあります。定期的な掃除で、汚れが深く染み込む前に対処することが大切です。

Q2. メラミンスポンジで擦っても大丈夫？

A2：光沢仕上げのポリカーボネートやABS製スーツケースなら使えますが、マット仕上げのモデルには向きません。また、強く擦ると傷がつくため、優しくこすることが大切です。必ず目立たない部分で試してから使いましょう。

Q3. スーツケースは水洗いできますか？

A3：ハードケース（ポリカーボネート・ABS・アルミ）は、基本的に水洗いはおすすめしません。水が内部に入ると、ロック部分や内部構造を傷める恐れがあります。濡らした布で拭くのが基本です。布製スーツケースは部分洗浄が可能ですが、全体を水洗いするのは避けましょう。

Q4. キャスターの汚れはどう落とす？

A4：キャスター周辺の泥や砂は、綿棒や爪楊枝で取り除きます。その後、中性洗剤を薄めた水で濡らした布で拭き、乾いた布で仕上げます。定期的に掃除することで、キャスターの動きがスムーズになります。

Q5. 白いスーツケースは汚れやすい？

A5：はい、明るい色のスーツケースは汚れが目立ちやすいです。ただし、定期的に掃除すれば清潔に保てます。また、スーツケースカバーを使うことで、汚れを大幅に防げます。
