I've used oven cleaner for years followed with Dawn.

The OP asked what was the best way to clean the oil off the engine in a 240d.

Does oven cleaner rinse off easily? Does it leave stains like other cleansers?

Does the hood release latch while the oven cleaner is soaking?

"Best way to clean up engine after an oil leak?"
Looks like a generic question to me...and you can tell by my farm examples that I was giving the bigger picture...
Included in that advise were two vehicles which I had problems with connectors on ...and which the FSM's later mentioned problems with...and went to extremes to tell how to fix... they were 1976 Ford Pickup F150 and 1995 Lincoln Continental ... the latter had a recall notice put out in 1996 which was not applied to our car... and that connector caused the Ford Dealership and the local mechanic to misdiagnose as a fuel pump problem... $600 later when that did not fix it... they replaced the head lamp/ antitheft module... $ 360... when that did not fix it they kept it for 30 days trying to get the intermittent non start to happen in their presence .... I finally found that recall notice and they changed that connector out... a $40 job ... but of course they did not refund the difference between that and the $360... It never happened again...
On the pickup truck... the later printed FSM went to great lengths to tell how to seal the connectors from water entry... which included replacing the connectors, putting special grease in them, and sealing up over the grease....
Most people can understand that high pressure moisture potentially inserted between the wires and their protective coverings it not a good thing and should be avoided as a general rule.

In both instance, especially the recall, it could be understood that Ford thought electrical connections should normally be resistant to water intrusion and if they aren't it's an unexpected problem.

Thank you for all the suggestions. I liked the oven cleaner humor!
