Backpacks are popular among moms, kids, and office workers because they allow you to use both hands freely.

remove trash


Turn your empty backpack inside out and remove any dust or debris that has accumulated in the four corners of the inside.

Make sure to remove the small dust and dirt that accumulates in the four corners of your pockets, which are often overlooked.
If it is difficult to remove with a toothbrush, you can try using something sharp like a toothpick.

remove stains and dust


If there are any dirt or stains that you are concerned about, use a damp toothbrush with detergent and lightly scrub the area (be careful not to scrub too hard as this will damage the fabric).

|Hand washing & washing machine |How to wash your backpack, tips and tricks

When washing your backpack by hand


Dissolve fashionable detergent in lukewarm water and press wash.

First, make a cleaning solution by filling a container with lukewarm water and dissolving the fashion detergent.
Then, put your backpack in it and wash it by hand.
When the cleaning solution becomes cloudy and you are able to remove the stains, rinse it off and dry it with a towel.
(To prevent the parts from deteriorating, do not press wash them for a long time.) If possible, after rinsing, spin the clothes in a washing machine (for less than 1 minute).
At this time, packing a bath towel in your backpack will prevent it from losing its shape.

When washing your backpack with a washing machine

Stylish washing course by turning clothes inside out and putting them in a net


When you're ready, turn the backpack inside out and place it in a laundry net, and wash it using a gentle washing cycle such as the "Fashionable Washing Cycle/Dry Cycle" using a fashionable laundry detergent.
(If you cannot select a course, please manually wash for 6 to 7 minutes, rinse at least 2 times, and dehydrate for less than 1 minute.) When dehydrating, use the backpack as described for hand washing. We recommend packing a bath towel inside.
Depending on the material, it may not be possible to release the water that has accumulated inside the backpack, so it may be effective to put a bath towel inside.

Precautions when dehydrating in a washing machine When dehydrating in a washing machine, "balance" within the tank is important.
During dehydration, water is blown away using centrifugal force caused by rapidly rotating the washing tub.
If you put only one item that has a certain size and weight in it, such as a backpack, and rotate it, it will put a strong local load on it, and the rotation will not be balanced properly, causing a rattling and loud noise. There is a possibility that an error will occur and it will stop.
When dehydrating in a washing machine, it is important to maintain balance in the tank, so instead of using a backpack alone, put a bath towel or other item in it and dehydrate it together. It is recommended that you do so.

How to dry and maintain your backpack

Newspaper in your backpack to prevent it from losing its shape


After dehydrating, stuff crumpled newspaper inside your backpack and let it dry flat in a well-ventilated, shaded area.
At the same time as preventing the backpack from losing its shape, the newspaper absorbs the moisture inside the backpack and dries quickly.

To make your backpack last longer

To keep your favorite backpack in good condition for a long time, ・Once it is completely dry, apply a water-repellent/waterproof spray to prevent dirt from sticking to it. ・Store it in a well-ventilated place. ・If it gets dirty, clean it immediately. Points such as wiping with water are also important.
Also, in order to use it comfortably and with love, please try to wash it regularly.
When drying clothes flat in the shade, you can also use a special net for drying knits etc.
If you can't dry it flat or don't have newspaper, open all the zippers and hang it upside down for better ventilation.
