Polishing ti (my first post!)(7 posts)

Polishing ti (my first post!)plowhorse

As someone out of circulation for several years, I have finally decided to get back into the game a bit. My trusty steed is a circa-1997 6/4 ti frame with 8-spd Athena. It was made in Russia and is unfinished.

Anyway, on to my question: I would like to polish the frame. I searched this forum and found several references to Scotch Brite pads. I was wondering about the method. Wet or dry? Do I need a polishing compound like Mothers' (or some suggested brand)? Do I need to be more careful around the welds? Thanks in advance!

Scotch brite will buff out any scratches, but to just bring back the luster, Lemon Pledge (the real stuff, the Generic versions don't seem to work) shines ti very well.

A green scotchbrite pad used dry will take off the dull gray and bring back a brighter more silvery look. Just lightly buff. No worries.

... stuff like perk, trichloroethane, carbon tetrachloride, etc, attack titanium and cause cracks. This is a very peculiar reaction as these solvents are typically harmless to most other metals. Be sure your cleaning and polishing compounds don't contain these.

On the other hand, titanium is unusually resistant to salt water. It is actually LESS prone to crack in seawater than in air. Compounds containing salt (sodium chloride) are OK.

One other material is destructive to titanium: cadmium. It is rare in consumer applications, but some yellowish-colored bolts are plated with it. Never let cadmium touch titanium as it will initiate a crack.
Great tips! Thanks! nmNessism

Scotch Brite is not necessarily to polish. To polish, I use the Lemon Pledge wipes. Works great

I'm working on an aluminum frame right now and it's such a pain I don't want to think about how tough it would be to work on ti. If you need to get scratches out of it, I'd think twice. I started with 220 grit sandpaper to get all the crap out of my frame and am working my way up from there. I'd leave it if it's that bad. As for polishing you might take 1500 grit sandpaper to it and wet sand it, then hit it with progressively finer polishing compounds (posts above mention some different ideas, like I said, i've never worked with ti). This should bring it to a really nice shine. FWIW
