Soldering Tip Maintenance: Tip Tinners
Proper soldering iron tip maintenance is important to extend the life of iron tips. Keep the tips tinned by frequently melting a small length of rosin core solder directly on the tip and then wiping off the excess with a damp (not wet) sponge. The Tip Tinners are small containers of solder in powder form with a special tinning flux. Wipe the hot soldering iron tip on the surface of the tip tinner, melting some of the solder on the tip. Wipe off any excess on a damp sponge. Source: Kester Solder Co.
