I hear ya that stuff is hard to get off. I used the brass brushes at first but was running throw them in no time and they were cloging up easy. Went to steel brushes lasted much longer and were stiffer so they went through the gunk faster. I used steel to get all the big gunk and hard stuff off then switched to a brass to finish and get the last little bit. Also found cup wire brushes for the drill worked better and lasted longer, can push harder and they dont just bend like the one your showing.
Cant remember if i used ones that were twisted like this.

I got them at menards and they were ones that had posts so they went into the drill, they worked alot better for me and lasted a long time compared to the wheel you have, i did use wheels like you have to get seams and some places.
