BillyO is right. You will see it.
Don't use anything but a brass Brillo like pad or a wet sponge to clean your tip. Or use a brass brush; sometimes. Don't use chemical cleaners.
The brass pads last a very long time. Never had to replace one.
Wet sponge is slightly worse because rapid temp changes can damage the cladding, causing micro fractures. Supposedly more important now that non lead solder requires higher temp of the tip.
Cladding wears away slowly with use and the underlying copper rots away, deforming the tip.This is normal. You will see it. The tip will look funky.
Old time solid copper tips could be reconditioned with a file, They had no cladding. But filing the new tips ruins the cladding.
Filing the old solid copper tips was a pain in the butt and had to be done often.
It also helps to clean your tip and apply a little solder to it before turning the station OFF. Supposedly protects the tip.
Watch a few videos on soldering. Most soldering is done with the chisel tips but other tips are useful for special applications. Like putting in small ICs with many leads.
The pointy tips are pretty useless, they do not conduct enough heat to the point of tip to be useful in most applications.
