Brilliant advice as usual.
So the key to keeping the tip in good order is just to keep it clean by a wipe in the pot of copper tool cleaner and then a wipe in the moist foam pad.
That copper tip cleaner just looks like leftover swarf from milling/lathe work with a bit flux in it.
Watched few videos and it’s also unreal on how far out of calibration these irons are.
There is ‘tool’ that has diodes and you simply add solder and touch to the centre and it gives the accurate temp tip to allow you to cal I rate it.
It looks like a flux capacitor type thing.
I’m thinking 375c is a good starting temp.
I even purchased a pair of magnifying glasses with leds and a set of verity’s lenses as my eyesight is not good close up.
I’m actually looking forward to having a little play doing this tbh.
I think that cleaner for flux is basically thinners here in the U.K. when I googled it.
Lmk if I’ve missed anything.
Thanks once again, what a great community!
