So I'm liking these titanium earrings I've have for a couple of months. One is just a plain ole ball, and the other two have a decent looking (but fake) crystals. I notice that the crystals started to look a little dull, so I headed to WalMart to get some jewlery cleaner. I was thinking of the nasty smelling liquid kind that I used to use on my gold earrings. Just dunk the earrings in and the come out all pretty and sparkly.
So the girl at the counter asked if she could help me and I explained I wanted some cleaner for my titanium earrings. She said, this one and this other one are basically the same. Just so you know, after you use it they will tarnish faster.
Tarnish? I guess I didn't think that titanium would tarnish. I explained that I didn't care if the metal was shiny...I wanted to make the crystals look sparkly. She then suggested a silver polishing cloth to use just on the crystals.

Can titanium tarnish? Does using jewlery cleaner make it tarnish faster?

Titanium is not supposed to tarnish, but of course is not impervious to scratches though.

"Titanium is immune to corrosive attacks by saltwater and marine atmosphere and exhibits exceptional resistance to a broad range of corrosive gases, acids and alkalis. Titanium is immune to microbiologically influenced corrosion and is physiologically inert and hypoallergenic." http://www.cybermarketing.cn/titanium/tishow.php?k=abouttitanium

CARING FOR YOUR TITANIUM JEWELRY
Titanium is a light, strong, lustrous metal. Pure titanium is as strong as steel and can withstand a lifetime of punishment. These factors, along with its lightweight durability and hypo-allergenic nature have made titanium an increasingly popular choice for jewelry, either on its own or as the setting for diamonds and other precious gemstones. However, despite its durability, titanium jewelry needs to be properly cared for.

Titanium jewelry is easily cleaned with water and a non-abrasive soap or cleaner. Make sure to dry well with a soft cloth.

Store your titanium jewelry in a safe place wrapped carefully and individually to prevent scratching.

If your titanium is set with diamonds or other precious stones, be especially careful, as these materials can be more susceptible to damage. Some fine jewelry pieces combine titanium with karat gold jewelry. Care for these pieces as you would your gold jewelry.
