Here are some tips to maintain your jewelry, clean them, and thus restore their shine.

Metals oxidize over time; this phenomenon is common and perfectly normal.
However, there are tricks to maintain your jewelry and restore their shine.

Here are some storage and usage tips to delay the process and thus preserve your jewelry:

 The first advice to avoid oxidation is to store your jewelry in a case or fabric pouches. This will prevent oxidation from air and humidity. Avoid storing them in the bathroom.

 Try to alternate wearing your jewelry and not have it on you all the time because contact with skin and sweat can accelerate oxidation. So remember to remove your jewelry at night and during physical activities.

To give your jewelry a second life, you can perform a specific cleaning to remove marks or tarnished appearance. But we recommend cleaning your jewelry after each use with a soft microfiber cloth.

 Soapy water or soft cloth:
Daily, you can use a soft microfiber cloth and/or clean your jewelry with soapy water, which will remove dirt and restore shine. Be careful to dry the jewelry properly.  

 Cola:
One of the most famous tips! Immerse your jewelry in a container filled with cola and gently rub. Finally, rinse with clear water and dry properly. Use a soft microfiber cloth to restore shine.

 Hot sauces and Ketchup:
Yes, it may seem strange but using hot sauces and Ketchup can be very useful to remove certain marks or surface tarnish.
For this, rub the piece with the mixture, rinse with clear water, dry, and rub with a soft cloth.

One of the most common tips is to gently rub your jewelry with a toothbrush and toothpaste. As with other cleanings, rinse and dry properly.
