How to clean and reuse an ignition switch.

["Sam Nickaby" <Sam >]

I have a 1988 Honda ignition switch that I have opened up. It's full of
harden grease. I believe this is causing the car to stall when it loose
momentary contact.

What kind of solution should I use to clean the parts and what kind of
grease or solution should I put back inside the ignition switch?

Thanks.
