Trucks' got 67,500 miles on it and I've neglected it a little. Anybody know what's the best cleaner for under the hood?

 

I use diluted Simple Green - full strength for the stubborn spots.

Here's a good read:

Another vote for Simple Green - Great stuff, and doesn't harm finishes or dissolve the asphalt on your driveway. (also, it is biodegradable - for all the tree huggers out there).

 

simple green then spray it all town with tire cleaner. shine stuff works great

 

i vouch for simple green also, im probably going to give my engine a nice cleaning this weekend. I use the plastic cleaner called son of a gun(can be found at walmart) and i havent used it under the hood for the plastics but i might and let you know how it goes

Another vote for Simple Green. I'm also fond of the citrus based cleaners for thes porpose. I helped my father pull the motor in his '40 Chevy. ( I know, but it's my Dad.. What can I say... ) The motor has been in there since at least since the late 60's when it was last restored. That owner drove it daily in non-winter months, then it sat in a barn for about 10 years. The engine bay in this thing was nasty, had that old-school grease built up all on the fire wall and front frame rails. The orange-based cleaner we used took it right off without damaging the paint on the fire wall. A little common sense does help, though. As with an clenaing product like these two, dont use them on a hot surface, dont use it in the sun, or if its been in the sun recently, and thorougly rinse afterwards to ensure theres no white residue. With a new vehicle, its important to not get certain things wet, as I'm sure you have seen in some threads here.. gl to ya and have fun

 

in the maintence bays at work we use simple green for everything

 

Simple Green it is. Gonna washout under the hood this weekend.Thanks!!

 

I am sure you prob already know this but i will say it anyway.
Don't wash your engine with a hose or you will have problems

 

So is simple green something you spray on then don't wash off? What if you used dialetic grease on you cops? can you then wash your engine down. If not with a hose then what would your recomend? Thanks

You have to rinse it off - it gets sticky if you don't. Just be careful. Low pressure, controlled spray, cover COPs and connectors so they don't get wet. Just apply liberal amounts of common sense and you will be fine.

 

AS long asyou use Di-electric you should be fine, I used GUNK engine degreaser in combo with simple green and hosed down everything under the hood, never had a problem.
