How do you clean up the residue on the electric iron?
Electric heater with cotton can be removed!
Personal experience: using electricity heating after the iron head dip rosin, then a steel saw blade (metal blade sawing) broken, iron head blade fracture with some impurities scraping fever. Clean the iron head and then touch the rosin to prevent oxidation and then unplug the power.
The welding tip is necessary to leave the solder welding head protection.As for the smoke on the pipe, soak it with alcohol for 24 hours before wiping it.On the black part of the process can not be dealt with, things used for a long time, there will always be traces, and do not have to tangle with this.
