Could BOTH my horns be bad?

Wanted to chime in just to say, even though I have a fsm and tested some things already, this thread helped me figure out my issue.

Horns didn't work, car sat a long time, mostly just cleaning up connections and having good grounds solved everything.

Cleaned up the horn relay and horns worked, loud too.

Then horns stopped working. Traced each wire and ground each section from relay to column.

Problem was the copper ring on the steering wheel was just too dirty to make connection.

I had cleaned up any connections that needed attention and installed a dedicated ground hub next to the battery to ground everything, lights, blinkers, reverse lights, etc.
Just never thought to clean up the steering wheel, I'm dumb.
