Best way to clean the engine bay

Hi all, I recently just did a trip up from Singapore to Kuala Lumpur with a friend who has a 991 GT3. It was a great trip for both of us and both cars are astoundingly quick. However, when I got back to Singapore, I noticed my engine bay was dirty. Do you guys recommend any particular way to clean the engine bay? Thanks in advance.

 

I do not turn the hose on the engine. Use spray bottles like windex and micro fiber towels. OK to do when the engine is warm but not hot.
Treat All engine cleaners as combustible...better safe than sorry.

BTW I use a shotgun muzzle cleaner (about 3 feet long) to get to hard to reach areas.

Always put towels or soft covers on the painted areas to prevent scratching.

 

My favorite way to clean the engine bay is with P21 Total Auto Wash and a microfiber towel. I've only done it when the engine is cold.

 

I just did some cleaning. I noticed the engine manifold is still a bit dirty... Do you know how to detail/clean out the small parts I can't seem to clean with a cloth?

 

Q Tip or toothbrush. Best
