I hope  that wasn't ACID paste! 


Alan:  "Plumber's Solder Paste" is PROBABLY acidic, but  mainly, it is a 
"paste" made of tiny spheres of solder-metal.  It  melts/flows with usual 
soldering heat, and is "painted on" the bright metal  before heating.  If used to 
"tin" a bare copper surface, it is WASHED  OFF before electronic components and 
"rosin core" solder is  used!
