Cleaning titanium frames?

What’s the best thing for cleaning an unpainted titanium frame? After building my new ride, there are some grease smudges and I wanted to check with some knowledgeable folks, before I do something that could effect the bike.

Pledge does wonders on my Litespeed Saber.

I use windex or equivalent on my Litespeed Ultimate road bike. Seems to remove everything and leaves a nice shine so you can see yourself suffer up the climbs!!!

Yep, Lemon Pledge was the first advice I got after I bought a Litespeed.
