How to efficiently clean the engine of a BWM car?

I noticed that the engine of my BWM car is getting dirtier and I want to clean it as efficiently as possible. What are the steps and products I should use?

First, make sure the engine is cool before starting. Then, cover any sensitive parts with a plastic bag or tarp to avoid getting water or cleaning products on them. Next, use a degreaser or engine cleaner and spray it all over the engine. Let it sit for a few minutes to allow it to work its magic. Use a brush to scrub any visible dirt or grease. Finally, use a pressure washer or garden hose to rinse off the engine and degreaser. If there are still some stubborn spots, you can repeat the process or use a cloth to wipe them off.

Alternatively, you can also use household items to clean the engine. Baking soda and vinegar make a great DIY engine cleaner. Sprinkle baking soda over the engine and then spray vinegar on it. Let it sit for a few minutes and then scrub with a brush. Rinse off with water and dry with a cloth.
