How do I clean my KOKKU at home?

Good old-fashioned washing-up liquid.

You will need washing-up liquid, a soft tooth brush, warm water (not boiling) and a bowl.

First, fill the bowl with hot water, then mix a few squeezes of good quality washing-up liquid and gently add your jewellery. After 5 minutes, use the tooth brush to carefully clean behind the stones or anywhere else that may have collected dirt. Then, re-submerge the jewellery for another 5 minutes. Finally, rinse with clean water and air-dry on a towel.
