I never liked or used the wet sponge. Mostly I use kitchen paper towels folded and I "scrape" the tip as I rotate it and clean it. Even some newspaper will do.

I have never had a temperature controlled iron. I have developed a certain awareness and sense. If the iron has not been used in a while I turn it off or I may blow on it to cool it if I know I will be using it shortly. If I am soldering something that needs more heat I wait a bit if I have just been using it.

I guess having temperature control is nice if you got used to it but I learned without it and now I do not feel the need.

The top advice I would give is (1) make sure the parts are clean - this cannot be stressed enough -  and (2) heat the parts and let the solder flow - you want it to flow and wet the parts well.

I use both sponge and brass wool.
However when I use the sponge, I soak it in water and then squeeze it to wring out all the water that I can.
I would not just pour water on it and start soldering.  As I've seen in some videos.

Since I bought a new Weller station with a compartment for brass wool in the holder, I'm not using anything else anymore. It's doing very well and doesn't cause thermal stress to the tip. Finding the right moisture level on the sponge seems to me like a science by itself.

Zero999:
Are you using lead free solder? If so, ditch it for real leaded solder. As I mentioned in the other thread, lead free solder is unsuitable for hobby use. It's very difficult to work with and the hazards posed by lead free solder, such as the more nasty flux, greatly outweigh those of lead. Wash your hands after use and you'll be fine.
