Thanks for that christian! I've done that before but it took 24 hrs. to work probably had to do with both the thickness of the chrome plating and the concentration of the HCL. Chrome can also be removed by reverse electroplating. Google "Caswell reverse electroplating" for lots of info. Caswell is the premier do-it-yourself plating company.

I assume it was originally TiN coated.

I guess this requires a different method to remove?

Google does not list HCl as a means to remove Titanium Nitride coating. Nitric acid is suggested but nitric will eat brass in high enough concentrations so you would have to do some experimenting.
