How to care

Wipe pure gold and pure platinum with a soft cloth or eyeglass cloth to remove dirt such as sweat and sebum stains.
Be careful not to rub too hard as this will cause fine scratches.
We also recommend that you store the chain in the jewelry box that came with your purchase at our store, with the chain stretched out to prevent it from getting tangled.
K18 and Pt850 are slightly discolored, so after each use, wipe the sweat and sebum stains with a soft cloth or eyeglass cloth to remove sweat and sebum stains. You can also clean it with a toothbrush or cotton swab.

How to remove heavy dirt

Brushing can remove sweat, sebum stains, hairspray, cosmetics, etc.
(Pure gold and pure platinum cannot be polished as they may get scratched.)
We recommend cleaning with a special cleaning solution, but if you don't have it, try cleaning it using the steps above.

How to remove blackheads caused by sulfurization

2. Dissolve lukewarm water and baking soda in a ratio of 3:1.

3. Add accessories

4. After the time has passed, rinse thoroughly with fresh water.

The silver contained in K18 may sulfurize and discolor the accessories due to the sulfur components contained in the air or hot springs.
This is a darkening that occurs when the sulfur component reacts with the silver in the gold. In this case, it can be removed using the reduction reaction described above.

For long-term use

・Depending on the quality of the hot spring water, it may cause discoloration, so please remove it before bathing.

・Although it is unlikely that the sea salt will cause discoloration, sand and stones can cause scratches. Also, be sure to clean it after swimming to remove salt buildup.

・When taking a bath at home, be careful about the ingredients in bath salts, shampoo, and body soap.

- Metals have high thermal conductivity, increasing the risk of frostbite and burns. Please be careful when skiing or using the sauna.

・If the product has been used for many years, you can restore its new shine by requesting a professional service.
