What is the most efficient way to clean my Audi's engine bay?

I want to properly clean and maintain the engine bay of my Audi. What are the steps to follow and what products should I use?

Firstly, make sure to cover sensitive areas of the engine, such as electrical components, with plastic bags or towels. Then, use a degreaser to remove any buildup and grime. Use a gentle brush to scrub hard-to-reach areas. Rinse with water and let it dry before conditioning the rubber and plastic components.
