Copper Wagashi Knife

Using copper products is the most natural way to care for them. Although there is nothing special about caring for copper products, please keep the following points in mind to ensure long-lasting use.

From day one, copper will  change. Unlike other materials, changing from a brand new state is positive for copper items.

If oil, salt or other contaminants remain on the copper and oxidise, a metallic odor and greenish-blue patina will eventually appear. This patina is harmless to humans, but to prevent it from appearing simply follow these basic care guidelines.

Daily Care:

After use, wash with a soft sponge or cloth and neutral liquid detergent. Rinse completely with hot water and dry thoroughly.

Scrubbing with baking soda and water also neutralises the surface from acidic to alkaline, thus preserving the copper's lustre.

Occasional Care:

Method 1: Restore the lustre

Wash with a paste of baking soda and water, rubbing it gently. Rinse with warm water and then dry thoroughly.

Method 2: Remove black stains such as tea stains

Soak in an oxygen bleach solution to neutralize the oxidized copper and remove dirt such as black stains.

Method 3: Maintain the surface's aged state while giving it a polished look

Melt beeswax on low heat, apply and polish the surface of the copper while wiping excess beeswax off.

Method 4: Reset the copper to its original state

Polish the surface with commercial polishing powder such as Picar to reset the copperware to its original state.

Other precautions:

Handle items with care and avoid scraping them with sharp objects, bending them, folding them and applying strong force to them. These actions damage the copperware.

Refrain from using copperware products if you have, or believe you may have, a metal allergy.
