What would be the easiest most efficient way to remove a anodized titanium scale and keep the stonewashed finish.
I don't want to flitz the scale and in the end polish the ti. I just want to remove the anno to get back to the stock finish of the scale.
 
Hydrofluoric acid such as multi-etch or whink rust remover. Nasty stuff, use gloves, respirator, and do it outside.
 
i guess natrium hydroxide drain cleaner like you can use for aluminum won't work with titanium, right?
 
Not that I am aware. However whink rust remover can usually be found locally at supermarkets in the bathroom cleaning isle. It works real fast, so it probably wouldn't hurt diluting it with distilled water. If you look up gavko's you tube page he has a couple of tutorials on anodizing that also touch on removal.
 
I've never tried doing that, so rust remover could take the blue ano off a scale without affecting the finish underneath?
 
It is an acid, so it will remove a surface layer. But keep in mind titanium anodization is a process of microscopically growing a layer of titanium oxide on the surface of the titanium. The color comes from how thick that layer is. So to remove that color, you physically have to remove material.
If the finish is something along the lines of a polished jeweled finish. You probably won't be happy with it, but something that is as muted as a stone wash will probably left mainly in tact.
