cleaning engine, what to use ?
Good day and how are you all. Yesterday I did an oil change on my e350 bluetec, have a question for you. The exterior of the engine is getting pretty filthy. I usually keep my engine and bay pretty clean, This is my first Benz and there are a ton of electrical connectors on the engine. So, what can I use to wash the engine down and get the grime ,dirt, and salt off of it? Will Simple green work safely and should I do it while the engine is cold, hot or doesn't matter? Thanks, have a great day, E350cruiser

I don't think that the process is any different for a MB.
Personally, I use Gunk (only if really greasy) on a warm engine, then pressure-spray it all. Always wrap the alternator with a plastic bag, learned that the hard way back in my teens.
Nozzle shouldn't be too close to the engine or components/connectors either. I clean from at least 12" away and knock on wood, have never once had any issues pop up after a cleaning (except for that one alternator 100 years ago...)

PLAIN WATER on warm engine always work for me.
In previous house I had 150 psi city water pressure, what was cleaning even grime accumulation.
Present 60 psi takes longer, but still washes out wet oil stains.

If you are talking to me, the answer is yes. I also use their concentrate on my P car wheels to remove the brake dust. Works as good as the $20 a bottle stuff that only cleans them twice. I buy it by the gallon and dilute it 1-5 for the wheels.

I'll give it a try. I could've sworn I'd tried it and was less than enthused, but my memory blows, so....

I guess it all depends on how greasy your engine is. Mine doesn’t leak oil so it wasn’t that bad. I don’t know if I would expect it to clean 30 years of neglect

i picked up some simple green pro HD concentrate at Canadian tire recently https://www.canadiantire.ca/en/pdp/s...-0532460p.html
used it in a spray bottle to clean gunk off parts, it seemed to work well, but nothing was super dirty, and I haven't used it yet to try and clean the engine/engine bay
