I think that was mostly about the outside of a wrongko, wasn't it?

To do the inside I use .22 & .17 rifle cleaning rods with bronze brush, followed by bristle brush.

If the build up of filthy wood is too bad I use a segrek, which is like a sort of reverse saw.

I'll post a pic of one later.

You can get into the top of the wrongko with scrapers or chisels to do a clean up.

To get rid of the dust inside, a thin piece of copper pipe long enough to reach the bottom of the gandar will allow you to blow it out.
