Do not do this, at least not unless you really can't get the coating off any other way. Odd that it's even there, actually...I've never had that happen, nor even heard of it.

Soldering tips are plated with a thin coating of iron, for resistance to flux and corrosion. Remove it and the tip will rapidly start corroding into nothing.

Don't use a wet sponge. It's bad for the tip and doesn't even work very well. Use a proper brass tip cleaner.
