I thought I would have a separate post with all the engine bay detail I did over the last couple of years. The process across all of them is the same. I start with an all purpose cleaner or a degreaser, depending on how bad the condition of the engine bay is, then I agitate with a brush. I then follow up with steam cleaning then I hose the engine bay down while making sure the garden hose is on fan as direct stream of water may cause damage to sensitive or exposed parts in the engine bay (especially with older vehicles).
