Clean the tip by flooding it with solder. Wipe it off on a damp sponge and re-tin before soldering.
Ideally, you use deionized water on the sponge to prevent scale from building up on the soldering tip, but a quick wipe with vinegar can fix that if it ever happens.
yassine - cooling down the tip isn't the main purpose of the wipe. If you were to use a temperature-controlled soldering iron, you'd only be getting rid of the blob of solder.
