Ave!
Not quite as harsh as lye, this is still one very serious mix and not to be used lightly.
I use this mix as the last gasp for cleaning seriously encrusted coins before turning to electrolysis. Be aware that this mix will remove your coin's patina.
Be careful with this mix...see the Pop Up for what happened to me when I wasn't paying attention! LOL! Use as directed and keep away from children!
