Johnson Mfg. Co. pledges to continue supplying these high-quality solid Sal-Ammoniac Blocks. For nearly 100 years this form of ammonium chloride has been used to promote rapid tinning of soldering irons.

Lengthen the life of your soldering iron tip. The use of a Sal Ammoniac block will aid you in the process of tinning by the tip and preparing to be tinned (coated in solder). Sal Ammoniac is a better alternative to using flux since it will not attack the plating of a copper tip.
