1. Regeneration operation when the tip temperature is 300 °C~360 °C.

2. Let the soldering tip and the resurrection cream repeatedly rub for a few seconds.

3. Clean the tip with solder sponge or copper wire.

4. Plated with a new solder wire layer, the soldering tip can be  clean and new.

If the effect of the regeneration is not obvious, repeat the steps 3-4 times until the desired effect is achieved, and then apply a new solder wire layer.
