A well maintained equipment is an equipment that lasts a long time! Washing instructions are not always indicated on traditional Japanese Judogi so we will report here some advice of our craftsmen.
It is also a question of respect that one owes to oneself and one's partner to wear a well maintained Judo-gi. Below, additionally to the basic guidelines, you will also find our personal tips to optimally take care of your equipment.
The Judogi, jacket and pants are made of bleached and sanforized cotton. The Japanese cotton, being of much better quality than the low-end cotton from China or Pakistan, shrinks less, and this thanks to a treatment called "sanforize". Nevertheless, it will shrink about 6% after a few washes.
We wash our Judogi with cold water, without washing powder, after each training, to eliminate the sometimes acid sweat, that damages the fabric. We machine wash it after 2 or 3 trainings, depending on the intensity of the training and the condition of the Judogi.
Be careful not to use too much detergent. More washing powder does not clean your Judogi better, and if poorly rinsed, facilitates the development of mold. It is better to simply wash it twice instead.
And no, unfortunately there is no way to fix a Judogi that blackened on the inside of the sleeves or the collar.
Against the common believe in Europe and North America - probably due to a certain legend in Karate - a belt can be washed!
To avoid excessive wear, hand washing my be preferred to machine washing.
Beware, colored Judo belts can slightly rub off. Do not wash them with your white laundry!
Do not store your belt coiled up, it is better to fold it.
Little used in Judo, and very rarely for full contact practice, here just a brief summary of how to maintain your weapons.
Varnished weapons do not require any special care. If you do not practice full contact techniques, you can keep those forever.
Unvarnished weapons require maintenance, they have to be oiled with vegetable oil about once a month. Just put some oil on your hands, apply it on the weapon and let it dry. Theoretically one layer is sufficient.
