How do you guys tackle the cleanup of the block, transmission, etc, after you've fixed an oil leak?

I have a minor leak from the back of the keg that runs down the back of the block and drips off the bellhousing, spraying the transmission, etc, behind it.
It has been leaking for a while, but will soon be fixed when I swap the keg for an FI Airgap... I'm wondering what the best way to tackle the cleanup is.

 

I use a pressure washer, being careful not to directly hit the electronics, after soaking it down good with Simple Green.
If you don't have a pressure washer, go to a car self service wash and crawl under there with a slicker suit. Be quick, they frown on that.

 

spray with brake cleaner and wipe with paper towels.

i like the advance auto brand brake cleaner because it doesn't burn your hands or melt plastic like the walmart brand does. it will burn your eyes so wear goggles or very good tight fitting safety glasses.
