If your using HCL and H202 Use only a plastic or rubber container. No
metals!
I use 1 part HCL and 3 parts H202 in cold weather and 1 part HCL and 4
parts H202 in warm weather. Not nessecery to heat the solution.
For a 6X6" PCB or smaller I have a tupperware square container about
10" square and cover the pcb with about 1/2 to 3/4' of a inch of etchant.
I found that I you gently pry up one side of the PCB with a plastic
fork or knife so that it is lifted up out of the etchant back and
forth the removal will go faster. About five minutes to etch a 6x6" board\
