Pops39p, welcome to the forum.
Clean it all off, but be sure to relube with your favorite lubes before shooting. CZs like to run a 'little 'wet', especially under the trigger bar, on slide rails and action friction points. Not dripping, but a little oil or your preferred lube every time you shoot.
Different users have different preferences, but I wouldn't lube the firing pin channel and ,maybe just a tiny bit on the extractor pivot point. In that extractor channel, gunk can build up and interfere with feeding and extracting.
Looking forward to your shooting results.
