Here's a labor-saving technique that can be achieved with a vibratory tumbler filled with ceramic media. It's good for cleaning hundreds of small parts all at once.

After mass finishing your titanium parts to radius or round the edges, the result is deburred and nicely rounded edges, but very dark titanium. Drain and rinse the parts and the ceramic media. Then, rather than dipping each part once at a time into Multi-Etch, reload your tumbler with the ceramic media and add one cup of Multi-Etch per 8-10 cups of media. The key is to moisten the media with the Multi-Etch. Add the dirty titanium parts and tumble 10-20 minutes, which will produce significantly brightened titanium parts.

Multi-Etch will not etch the ceramic media but it's best to clean and rinse between operations.
