1. Learn the causes and types of stains on suitcases

2. Oil stains and hand grime

3. Mud and rain stains

4. Mold and discoloration

5. Rust and dull metal fittings

1. Scratches (scratches)

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 .

Title

2. Oil stains and hand grime

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.

Title

3. Mud and rain stains

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.

Title

4. Mold and discoloration

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 .

Title

5. Rust and dull metal fittings

Don't overlook rust or tarnish on zippers and corner protectors (metal corner parts).
It is caused by humidity and salt (seaside and sweat),

This can be prevented by simply wiping the metal parts lightly with a dry cloth after use.
If rust is already visible, gently polish it with a cotton swab and metal polish to restore its shine.

💡 ちょっとした豆知識
実は「黒ずみ」と呼ばれる汚れの多くは、色移りや擦れによる付着汚れです。
つまり、スーツケース自体が傷んでいるのではなく、
表面に他の素材がくっついているだけのことが多いのです。

2. Preparation before cleaning: cleaning tools and precautions

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 .

4. Timing of maintenance

1. Basic cleaning kit

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

アイテム 用途 注意点
中性洗剤（台所用） 表面の軽い汚れや油汚れを落とす 濃度が高すぎると変色の原因になるため、水で薄めて使用
やわらかい布 or マイクロファイバークロス 表面の拭き取りや仕上げ磨きに 硬い布は擦り傷をつける可能性がある
綿棒 or 歯ブラシ（柔らかめ） 細かい溝やロゴまわりの掃除 強くこすらず、優しく円を描くように動かす
消毒用アルコール or 除菌スプレー 手あか・油汚れの除去 光沢仕上げの素材には少量ずつ使用
メラミンスポンジ（必要に応じて） 黒ずみ・擦れ汚れの落としに効果的 素材を削る力が強いので、樹脂製のみに限定して使用

Just a small point,
Rather than starting right away thinking, "Okay, let's clean," it's better to wipe the whole thing with a dry cloth first and then start working.
This makes it less likely for dust and sand particles to scratch the surface.

Title

2. Checkpoints before cleaning

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.

Title

3. Wrong maintenance methods (common mistakes)

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.

Title

4. Timing of care

The ideal is to "lightly wipe it down every time you travel."
But in reality, it tends to get put off.
In such cases, it is OK to simply give it a thorough cleaning at the change of seasons (2-3 times a year) .
If you clean it before your end-of-year cleaning or preparing for your next trip,
On the day of departure, you can also enjoy the small joy of being able to leave with a clean suitcase.
