The S10 has oil all over the lower engine and close by parts. The oil lines appear to have been leaking, along with a failing cv axle boot spewing grease.

The lower engine on this ZR2 S10 is covered by skid plates, so normal driving in the rain does not get the lower engine washed off at all.

I do not want to use engine cleaner to get off the oil, it is pricey, can sometimes cause damage to components and plastic parts, and can be toxic. I am doing the work in an attached garage.

I recall seeing a commercial where ducks soaked in oil from the Exxon Valdex accident were cleaned of oil using Dawn dishwasher soap. We have a big bottle of Dawn from COSTCO, so I decided to give it a try. I mixed 2/3 hot water and 1/3 Dawn in a sprayer bottle. I then placed old sheets under the S10 and sprayed away. Not sure how it will all turn out- but I am hoping it beats going to Advance Auto on a Sunday and spending big bucks on a toxic engine cleaner.

I have reservations about caked on stuff, and I would expect some need for scrubbing with a brush or something. I am curious to see how good it knocks the grease down though, I never thought about using it for that...

It works, but you need to remove the caked on crap first. Then using a brush in a bucket of hot soapy water, have at it. Or, go to the car wash with a set of ramps and use the high pressure wand. Less of a mess on your end if you do it at the car wash.

Ivory dish soap work pretty good and I use to mix it with simple green or fantastic with scrubbing bubbles.
That removed a greasy mess quite well!

i just use simple green, its not that bad at walmart. and we got the spray bottles a long time ago but she gets the gal refill at BJs(like cosco). it is good to breath or touch, doesnt affect paint or plastic, and works as well as the caustic ones. we use it all over even on things we eat off of like the grill, i havent lost any brain cells yet, at least not from that.

Is this safe for all type of finish? Hows the dilution compared to Megs degreaser?
