Sal Ammoniac 1/4 lb
Sal Ammoniac, also called a tinning block, quickly cleans any carbon build-up that collects on the tip of a soldering iron. Simply rub the tip of a hot iron against the block and in seconds, the tip is clean, bright and hot.
For best results and longer lasting soldering iron tips, use the tinning block occasionally to re-tin the surface of your tip. A moist soldering iron sponge is ideal for routine maintenance while soldering to keep the tip clean.
