Hi guys I'm new using the homebrew mix of HCL 30% and H2O2 3%, and
would like to know what is the best temperature for good etch time??? ,
right now when i do a fresh mix, the etch time is really fast around 5
minutes , but if a week later i want to reuse that mix now clear green
color my etch time goes up to more than 30 minutes!!!!!!
Thanks
Bruno
