I have been using this for more than 10 years, almost every day:
 https://www.maerklin.de/en/products/details/article/70910/
unfortunately it is no longer made.

Some years ago I did see the same for sale as a no-name thing,
mine is labelled 'Voltcraft LS50'

One thing, NEVER use a wet sponge to clean plated tips, it kills those,
always wipe it clean with some paper napkin.
That way, at least for me, the tips last forever.
The wet sponge thing is a trick to sell tips.

And you need temperature control.
