The result

Not what I expected ... There is no big difference between the two.
Then again, maybe this is not silver.
Our housekeeper suggested to add lemon to the mixture of vinegar and bacing soda, see the
result...

you were right Fastidious and Breeze, Lemon is the answer. It took us only 5 minutes to clean it
up, just soak and rub.

I take bunch of my silver stuff to some jewelry store. and after 10 minutes they give them to me brand new sparkling like I just bought them. You can find the liquid they use for silver cleaning in any supermarket but I was told it’s not safe to use it home.
I don't know what they are made of, coz I got them from those shops in Mubarakiya where they sell Afghani dresses and material, I got 2 cuffs for 10 KD, u think it is silver?
and sure I could have got the liquid silver cleaner, but I wanted to try something new:)
The color looks totally silver to me and the way it’s rusted as well.
