New to engine detailing

[Markymapo]

So I assume (with this mess) I clean the surface of engine compartment and inside of hood with some APC diluted appropriately followed by some 303 Protectant. I have only tackled the outside of cars ( coming up on one year anniversary on taking Mike’s class in Medford) so this engine cleaning has me a bit perplexed ( too many crazy electronics to mess up)
(it’s my 2016 M4)

The electronics on newer cars like yours are sealed so you really don’t have to worry about get them wet with water or cleaner. The only precaution I take for an engine detail is to cover the alternator. Go ahead and give the engine a spray down with the hose. Then spray it with your favorite APC, agitate the surfaces with a detailing brush, hose off the cleaner and then dry it with a Sidekick or towels. 303 is a good dressing.

I have to recommend Amazing Roll Off. (https://www.autogeek.net/amazing-roll-off.html) I did the engine on Mom's Lincoln with it. Light hosing of the engine, sprayed Amazing Roll Off, let it dwell for a minute or so, hosed off, blow dry. No agitation, no dressing. The pictures speak for themselves.

I used to be able to get Amazing Roll Off at a boat supply store. I used it on wheel wells but never bought it again.

I covered up alternator and sensitive electronic parts using aluminum foil (I problably over did it), sprayed cleaned with Sonax Engine Cleaner, hosed it down, blow dry then dressed it up with Motor kote.

The alternator pulley has a over running clutch with bearings in it. The grease seal on those aren't very good. You can easily wash the grease out. Then a few weeks done the road it goes out on you. It happened to me . It was only a few months later that I found out it was my fault.

Things like that are the reason I don’t go messing around spraying water & degreaser on anyones engine...

Similar to cleaning door jambs to perfection, so good that you clean the grease off the hinges, but at least it won’t cause the doors to fall off. Lol.

I don’t do engines when I detail for pay. Too much opportunity for the client to turn around and blame me for some kind of problem they have later on.

I heard a story where some noob youngster ruined a Cadillac by powerwashing the Northstar engine.

Yikes!

Yikes!

And the customer went and payed Thousands out of his own pocket to get a new engine installed.[emoji2359]

Did the detailer have to pay anything later on?

As far as I know he was let off scott free. That story bugged the hell out of me...
