Today&#8217;s soldering tips consist of different layers of metal. If a temperature shock occurs when cleaning the tip with a damp viscose sponge, the metal layers also expand differently. This can cause micro-cracks on the surface. This leads to increased wear, and if you are now working with lead-free solder, it attacks the vulnerable spots.<br \/>\nSince no thermal shock occurs with the dry sponge, this is the gentler solution.<\/p>","protected":false},"excerpt":{"rendered":"<p>ERSA brass wool dry sponge When using lead-free solder, there may be increased oxide formation on the surface of the soldering tip, which can very quickly lead to a black non-wettable interface.
