provided cover. It is airtight so it doesn’t matter if the container
falls upside down. Let the liquid rest for a few hours. One can
observe a deposit at the bottom. These are small dirts from the
cleant jewels.

shaking it. Throw awa the deposit, rince and dry up the container.
Transfer the HOSEKI concentrate back in its container.
3. You can use the liquid again to clean other jewels or keep it for
the next use.
Eventually, you will still have to change the HOSEKI liquid when you notice that it
doesn’t become clear anymore even after a few hours of rest.
