Soldering iron cleaning sponges cost about nothing. I can go
to the kitchenware department & pick up a pack of 3 cellulose
sponges (packed damp to keep them soft until sold) for less
than a buck. They cut up into I forget but maybe 20 soldering
iron cleaning pads. The one trivial difference is the colours.

Thanks. I wasn't certain that the sponge was made from cellulose.

I've tried that a few times, and the sponge usually just melted and
charred. I probably was using plastic sponges.

If I can find some melamine sponge, it should work without water:

Same with a brass or stainless scrubber.

A wet folded paper towel sorta works, but not very well.

If even that's too much, wet denim also makes a good iron cleaner.

Good idea. I'll give it a try. Anything to avoid paying $5 for a
TC205 sponge.
