Titanium post pickling procedure

Anyone who can help! After pickling titanium what is the best way to polish it before anodizing.

The best is to use electropolishing in salty solutions. You even do not need pickling before - everything will be done together.

Try doing your pickle with a nitric :hydrofluoric acid at say 35 % HNO3 and 2 and 1/2 % HF. Machined titanium comes out as bright as a new American ten cent coin. You may not have to polish, or polishing may be easier.

Need some clarification. What is the surface finish of the part now? Does the word polish refer to esthetics or a specific RMS value? As a quick guess, perhaps your best method would be hand buffing part. If you have a lot of parts, mass finishing would be more cost effective. I can't make recommendations without answers to first 2 questions.
