Hello,
I have been using the Muriatic Acid Hydro Peroxide etchant now for the last few projects. The first time I mixed a batch it etched a pc board in about 3 minutes. Incredible, great stuff. I then placed it in a sealed container for the next use.
For the next project a number of weeks later I pulled out the bottle to etch another board and it took a little over a hour to etch a board. Holy cow! So I added a little freshly made stuff to finish that one.
Today I went to do another and same thing. Old solution took forever so I made a brand new fresh batch and etched the board in 3 minutes.
Why is the old solution taking forever? I thought this stuff is supposed to get better as you use it? Is this a temperature problem? Any thoughts would be great...
Thanks
