I was perusing Wal-Mart's automotive section the other day and came across this stuff. I haven't tried too many eco-friendly products and it caught my attention with one of its suggested uses being engine bay cleaning. So I figured I'd give it a try at $3.84 for a pretty large bottle.
Before trying it on the engine bay, I did clean my bathroom sinks and shower, of which it did very well. However, it has a surprisingly caustic smell - one that stings the nostrils much like Sex Panther.
Anyway, moving on to the engine bay cleaning, I chose the following engine bay as a guinea pig. It's an '07 Volvo S40 that is very well taken care of, sans a little neglect in the engine bay. The engine bay seemed like the perfect candidate being that it was covered with dirt/dust, but not to the point of no return. Seemed good to me.
Here's the Holy Cow product I used...


Engine bay before cleaning...


After misting with water, spraying Holy Cow liberally over the entire engine, agitating the easy to reach and dirtier areas, then rinsing...


And after the obligatory dressing with CD-2 (please don't mind all the fuzzies on the flat surfaces, I stupidly wiped down some of the areas with a terry towel that was shedding
)...


It did a pretty darn good job of cleaning and degreasing. I was quite surprised. It seemed to just melt some of the easier grime right off and only took minimal agitation for the dirtier areas. It easily rinsed clean and left no traces of residue at all. I would venture to say it cleaned better than my usual Meguiar's 4:1 APC mixture that I've been using (I've got P21s TAW but save that for more momentous occasions due to its price).
In conclusion, for the very low price and the fact that it's eco-friendly, I would definitely recommend picking some of this stuff up not only for use on engine bays but for other diluted uses around the house as well (you can even use it on clothes stains and/or add it to the wash... wow).
