What do you guys know about chemical metal etching?
>>2971916You'll put your eye out
>>2971916I think chrisfix on jewtoob did a video on how to chemically etch tools that looked pretty easy to do...
>>2971916You can do it with a 9v battery and some cotton. Lots of guys who make knives do that way, so there's a lot of videos explaining the process.
>>2971916i am a dental student, the same acid thats used to etch teeth (hydrofluoric acid) for composite filling etches aluminum surfaces to a dull surface
>>2971916i put some concentrated vinegar through my dishwasher empty, then the next load all my metalware came out super shiny
