Chasing squeaks....pedal maintenance tips?

I’ve been getting some squeaks when pedalling and we all know how fun that can be to chase down :rofl::rofl::rofl:

I’m running Look X-Track pedals/cleats, but general advice is welcome too!! I got the tool to remove the pedal body and I plan to regrease the spindle. Should I do anything to the pedal body itself (degreasing? Wash with bike wash detergent?)

For all the time I’ve spent washing my bike and fretting over maintenace, waxed chains etc. I’ve never really thought about pedal maintenance before.
