2: Ultra
sound method
Dip
your item of jewellery in an ultra sound
machine, this is basically a very high frequency
vibrating reciprocal filled with a special
cleansing fluid and follow instructions.
These
small machines can be bought at many high
street jewellery outlets at a price of around £20
to £30.
Kindly
note that this method is not without risk
as an already loose stone may be made looser
still and drop off.
Also unless done professionally it may not
give a satisfactory result. |
