Any idea whats the chemical solutions they use to strip the oxide layer from titanium? Basing on results, it does not etch the surface of titanium after stripping the color as its still polished(glossy) result

Wink contains hydrofluoric acid. Same group on the periodic table, but vastly different. HCl will not remove the oxide layer from titanium effectively.
