How do you clean black engine cases and cylinders
So I thought about this harley Engine brighter to bring my engine to nice condition but I am not sure if this wont harm any surfaces and create any mess. I am sure someone figure out good way to clean this wrinkle black engine and cylinders.

hot water and Dawn dish soap works for me as far as degreasing.
I follow up with some S100 engine brightener....works great on the black surfaces.

Yes! I had good luck with Simple Green, none other!
I use pig spit on my engine, and it does attract more dirt. When I want to clean it, I then use the simple green to de-grease the fins and then once it's dry, I reapply pig spit..or any silicon spray really.

+1 on Pig Spit. I like it better than the HD or S100 Engine brighteners as it's not as thick. I'll typically use car-wash soap on entire bike, blow it dry and spray the Pig Spit on the engine and wipe excess off of chrome.

Yeah...just a rag when it gets on the chrome pushrod covers or exhaust or whichever. No biggy. Really any silicone based clear spray works good. The silicone wont evaporate when the engine gets hot.

Regular dish soap to clean it, then S100 engine brightener. The engine brightener spray brings it back to looking like showroom condition.

I believe it is. It's very similar to the HD engine brightener.
