I have always been fairly reasonable at soldering but I learnt something really useful by reading a old radio service instruction book and decided to try it out.
I always realised the importance of using Flux but didnt know to coat the iron tip with Flux after use and before you use it.
So after reading about it I decided to give it a go.
Now I'm getting a much longer life out of them ( 2 -3 months ) and I don't have to clean it as much as before. Are there any other useful tips you guys can think of.

I was taught from a young age to leave the tip coated in solder to prevent oxidation.

Another way to lengthen the life of tips is to use brass wool rather than a wet sponge.

The tip has to be kept tinned to make soldering as easy as possible. I've been told by a few purists that the iron should never come directly into contact with component leads but doing things this way (melting solder onto the tip and then sweating it across to the joint) just results in overheated components and the risk of a dry joint in my view.

I don't see the need to use an external flux source in soldering of electronics. Flux is corrosive and will eventually eat the tip away and there is already plenty of it in the core of standard rolls of solder. The corrosive properties of flux is what allows it to clean the surface of the area to be soldered and makes the solder take quicker.

A valve a day keeps the transistor away...
