-The leather is left uncoated to maintain its natural texture. Water can cause stains, fading, color transfer, or deformation.

-For regular care, wipe with a dry cloth or brush. If the leather feels dry, apply a small amount of beeswax with a cloth, spread it evenly, and then wipe off. This helps with water resistance.

-If stains occur from rain, gently wipe with a damp, well-wrung cloth and let air dry in the shade. Avoid direct sunlight, irons, or hairdryers.

-Clean stains and store in a cool, well-ventilated place away from sunlight.

-For long-lasting color, hand wash in cold or lukewarm water and hang dry away from direct sunlight.

-A light coat of beeswax is applied to the patina surface. If it gets wet, gently wipe off any water droplets without rubbing the surface.

-Do not heat the kettle when it is empty. 

-After use, wash and dry thoroughly. 

-The handle may become hot during use. 

-Avoid filling the kettle to the brim with water. If the inner tin lining gets scratched or peels off, please have it repaired. 

-Clean and polish with baking soda or a gentle abrasive to restore its shine. Enjoy the deepening color and character of the copper as it ages.

[Knives]

-Avoid cutting bones, frozen, or partially-thawed items, as this may risk damaging the blade. 

-Do not use a dishwasher or drying machine, as it can cause the handle to crack. 

-After cleaning, thoroughly dry both the handle and the blade with a cloth. 

-If rust appears, apply baking soda to the blade and clean it with steel wool or a sponge. The rust is not harmful and can even serve as an iron supplement, helping to prevent iron deficiency and anemia. 

-It is recommended to sharpen the knife every 1-2 years with regular use. If the blade becomes dull or damaged, Yashima Iron offers repair and sharpening services. Please contact Oshinsha for assistance.
