mnewxv · 08-25-2008, 08:33 PM

whats the best way to do this painlessly? car has 102k and its grimey, just looks like a little dirt/dust on everything. how do I make it look brand new again?

Get a good degreaser and go to work.

Do not blast it with water, there is alot of sensitive electronics under your hood.

If you do want to rinse your bay after letting some degreaser set on it be sure to cover your electronics up first or it will be a costly clean up...

I tried alot of things to get mine clean found best way was with a rag and a degreaser

I may be a certified idiot, but I degreased my wife's 1995 Ford Explorer at the local car wash and it did a beautiful job. I left the ENGINE RUNNING and used the degreaser option which I was careful to spray only on the engine compartment. BE CAREFUL, because I have heard this stuff can damage your paint if you don't get it rinsed well. After the degrease, I switched to clear water to RINSE THOROUGHLY. It looks like a new engine. I did not find any problems doing this, but it was a Ford and not my 1988 Supra.

Alot of degreasers say specifically do not apply to a hot/running engine

I have seen cheap degreasers at the dollar stores good brands like Gumout. I use oven cleaner on my diesel benz.
