What product do most use?

Because of the unusual location of the M96 and all the shielding underneath ,the many electrical connections on the top of the engine are very protected from the elements.But those electrical connections are buried under the inlet manifolds. Checking them all if the engine misbehaves after washing could take days.As we say in the biz - bring it on -it is a "Time & Cost " job so it is blank check time.
If you care to Google "washed engine problem" you may understand.
On an M96 the OCD cleanliness issue is UOA not outside shine.

most of the grime is at the undercarriage which is where I will concentrate on. As far as the top of the engine near the intake manifold I will probably concentrate around the out edges not directly of the top as I cleaned that area as much as I could by hand.
