I have pics and need to post them. So you can't find Hydrochloric acid easy in NYC with good reason. I did find a cleaning solution in home depot that had somce hydrochloric acid in it. I did get the pcb etching. Pcb works quick on nickel but not at all on chrome. My bridge and tailpiece are chrome I put it in a container to let the fumes get to them, no luck, I then soaked them in the solution for two days. It dulled them for sure, then I dipped quickly in the etching solution and washed off. The results are pretty good but it's a longer process with what I used. The tuning pegs came out great. I suggest after this is done, put all items in a sock or heavy plastic ziplock with screws, keys and other metal objects to scuff them up naturally with sandpaper or steel wool.
