Can horn button contacts be cleaned?

[franbev]

The horn button on my '74 Ascona isn't making contact. I've determined that the horn is functional by grounding the wire going to the horn button. How do I get the button off to clean the contacts? Are there any known issues with Opel horn buttons? This is a stock Opel steering wheel/button.

Horns draw a pretty good slug of current, if there isn't a relay feeding power from the switch to the horn I would add one.

I believe the is a ground wire that comes out of the steering column that supplies the ground to the horn ring. Before you mess with the steering wheel and horn contact assembly I would verify that this wire exists in an Ascona and if it does make sure it is properly grounded.
