Engine cleaning
I have had my engine cleaned by the Mercedes dealer for the time I had it, but I want to start doing it on my own.
I have looked at this video, and it shows that Mercedes only trust Sonax 607. They even apply without any fear.
Anyone used it?

Well I use a 50/50 of simple green to water with a soaked rag. Wipe everything down then dry off. Pull all the plastic and break out the wet/dry vac. Maybe once every two months. I don't drive around with the hood open so I don't care too much.

I do it like the video and never have issues… keep in mind technique (distance to objects) would vary if using a 1500 vs 4000 psi pressure washer. There’s more, the orifice size and angle of the tip will vary the pressure.
Point of reference, I use a 3000 psi 2.5 GPM PW, but with the right tip (down to 1200 psi) I can comfortably hold my hand less than 12” from the tip.
I’d say as long as you use a 25 or 40* tip and keep it ~6” away from components you should fine. I would avoid blasting the felt heat shield/sound lining on the firewall.
We used to have a steam “jenny”…. that was awesome for cleaning REAL grime and you didn’t need chemicals, usually. The pressure was low, <1000 psi, but it put out scalding hot water/steam.

I wash all my engines. Been doing this forever, and as long as it's on the up and up with no frayed wires and exposed leads you'll be good. That said I only use a foamer like this, sprayed from about 4-6 feet away and let the soap do the cleaning. Use a good soap. Then rinse using the same nozzle without the foamer attachment. Then just dry with a hand towel.
I don't "seal" anything when I do this. Remember the engine bay is designed to be exposed to the elements, no different than driving when it's pouring out. Just skip the pressure washer and no shine products post-washing.
On our 160k-mile M272 I couldn't resist cleaning it when I did the oil plug fix. +10HP when clean, true story.
And don't forget the bike
