To remove the slide you first remove the bicycle chain type link on the right side, this will allow you to remove the slide stop and remove the slide.
Slide bushing comes off by depressing spring pressure from front of slide, then bushing can be twisted off, to clean the gun just soak the whole gun minus the grips in solvent ( take into account all flamable product safety practices and do it outside) for about 5 hours and then clean with tooth brush , cleaning rod and cue tips. Then dry , oil and resassemble it . Note if you soak in solvent no need to remove firng pin for cleaning, gas disolves grease.
If you shoot corrosive ammo, clean barrel , slide with ammonia to remove corrosive ammo effects and then clean / lube as any normal gun.
