Dear Kumar:

A clear lacquer coating is one way to protect silver from tarnishing.

Dear Kuma,

In case of electrical parts, you should consider electrical conductivity/resistance of silver plated parts prior to applying anti-tarnish coating.

So, I recommend "Tarniban" for this application made at Technic

Also, For jewelry and flatware,you should check the clear coating material changes to yellowish or not with the lapse of time.

Tarniban has several advantages as follows:
- No lacquer coating.
- No discoloration
- Easy stripping without any damages
- Anti-tarnishing,and lubricating in side effect.
- Does not affect electrical conductivity.

Mr.Key,

What is the life of Tarniban as compared to untreated/uncoated and normal silver or silverplated products ?

I need to ask, What is the best thing to put over sterling silver and 14 kt gold jewelry to prevent tarnishing. Is there such a thing?
Thanks,

Hi, Gennelle. It's probably perfectly obvious to you whether you are a consumer with 3 or 4 items to protect, and limited to consumer-friendly clear coatings, or whether you are a jewelry manufacturer producing tens of thousands of pieces per day, and free to install an electroplating line . . . but unfortunately it isn't obvious to the rest of us :-)

If you are a consumer, Les Trinity's advice is probably the best thing open to you. Good luck to you.

I am a consumer with big problems with wearing jewelry that turns. Thanks for your answer. I was selling jewelry but found out there is too much to know for a novice.
Thanks for the reply,
