Dear Technet,
Help!!!!
Can any of you metallurgical/chemical wizard types help me? I need to strip tin (?) plate off of brass. Hopefully without etching the brass.
The plating solution was;
Flouboric Acid
Stannous Fluoroborate
Thiourea

This stuff soldered great last week but will not wet this week.

I greatly appreciate any help,
Dan
