cartier cleanning kit , around $40 ebay.
Got mine for free from buying gen.
It comes with a spray , soft brush, micro fiber cloth.
This spray is a important part of this treatment.
it works like a tire shine, spray on and brush it,
Leave on for an hour, then clean with the microfiber cloth.
Wash it off with cold water, Strong dish washing gel. Not foam type.
use another tougher tooth brush to clean it. Don't use a soft one.
make sure it's fully try after , use a hair dryer in COLD mode is best.
This help to get the silk feel better
now here comes to important part.
choose the correct polish cloth.
All you need is a eye glasses clean cloth.
However, NOT mircofiber or towl material. These type will not get the same result
Mine is a thin cloth, the material is slippery, and a bit sheen on surface.
Sorry, I don't know what this kind of material is call, name it if you know.
this cloth give a slik and sheen polish to the bracelet .
Rub with force link by link. once you rub it on, you will see the shine already.
after all done, the bracelet should be so silk that it can slide off your finger.
without this same material cloth, the shine will not be as gen like., and not as slik.
Once you use the spray, you can feel how smooth it is already before wash.
so guys, don't really special, but you need the right tools.
