How to Maintenance

Natural materials for cleaning

The cleansing method of these wood wares has been the same for ages; cooking rice with the same pot used for milling, transferring it to the rice bucket, then washing the bucket with palm scrubbing brush and rice bran that was extracted during the milling process. Our unique goal is to deliver the entire experience of a natural lifestyle, from production to the cleaning process. Rice bran not only absorbs the dirty oils but doubles as a finish that polishes, leaving behind the aromatic qualities of rice bran oil. The wooden counters at sushi restaurants are always so clean because the chefs polish it with rice bran everyday. For households that don’t have access to rice bran, we have organic rice bran (no use of pesticides, herbicides, chemical fertilizers) available, that is made in collaboration with the farmers growing the inochi no ichi rice.

Clean the lunch box with rice bran.

The outer surface of the bento box can be washed using rice bran, but for inside the box, we have created a special cleansing balm, the Tsunekichi original beeswax. The balm is made with cedar oil extracted from excess saw dust, natural bees wax, and walnut oil blended together. Taking a small amount of this and rubbing it on the surface will protect the wood from drying out and cracking, allowing for a polished, long lasting finish.
