Fill a bowl with lukewarm water and add a few drops of mild dish soap (no detergents).
Place your jewellery into the bowl and allow it to soak for 15-20 minutes to loosen any built-up dirt.
Then, use a soft-bristled toothbrush to gently clean the jewellery, notably the hard-to-reach areas.
Rinse the cleaned jewellery with running water to remove all dirt remnants and soap residue.
Dry gently with a soft, lint-free cloth (no paper towels), or simply leave the jewellery on a cloth to air-dry. *Avoid using machine cleaners like an ultrasonic jewellery cleaner
