My titanium KeyBar® looks a little dull. Why is that, and what can I do? We use a process called anodizing to color, treat or customize the titanium. Oil from your hands may dull the color. That’s easy to fix, though – grab a cloth and some Windex and give it a light cleaning. The color, treatment or customization will brighten immediately. TweetSharePinShareWhatsAppRedditEmail0 Shares
