PCB making?

Hello,
Can I use H3BO3(boric acid) and HCl for etching?

Well I have seen etching on steel with 50% boric acid and 50% water so it should eat copper.

I have etched PCBs with pickle juice.

Hahaha thank you for your answer. I have 3% boric acid, maybe I can use some ratio with water and HCl. I will try it today. Thank you.

As much as I thought it would be a laugh the pickle juice etched the circuit.

Thank you

Ok, but I was asking if I can use boric acid for etching.
