Correct, don't do anything to the engine bay when the engine is hot. The degreaser will just evaporate away and obviously cold water on the hot engine block isn't recommended. However, I found the degreaser actually works better when the engine is warm. From a cold start you can let it warm up for a minute or so. If you've been driving, let it cool down considerably though.
