I have information that to wash the metal part (my metal parts Cu plated with Sn) is use NaCN, I have some question :
1. Is it dangerous Na CN solution (1%)?
2. What the supplier (brand) name for Na CN 3. What the other solution that can be use for cleaning (Cu plated with Sn)

NaCN is sodium cyanide and it is HIGHLY TOXIC, even at 1%. If you want a substitute, ask your local chemical supply house.
