What about getting the dead bugs 'n gritoff of the top of my intake manifold, that's probably the dirtiest and toughest to clean for me.

 

so spay everything under the hood ? is there any things this would damage ?

 

Cover up your alternator for sure; I had to learn the hard way to find this out. Or you can spray everything down but I would pull the negative cable off the battery and wait 24 hours until I connect it back up and start the engine up. Or you could just wing it and take the chance and most likely nothing will go wrong such as other fortunate people have been doing.

 

I have used the black magic tire shine spray many times in the past just cover up the battery terinals as well the alternator and you should be fine I havnt had any problem and it looks so clean.

 

I've been just putting plastic over the altinator and the fuse box, and spray the bay with simple green, wait about 15 to 20 minutes and hose it down with water, then just dry it all out... and it all comes spotless. Never heard of the other way. interesting idea tho!

 

Ok gonna ask again does this work on Engines that have yrs of dirt n gunk build up? I need to clean the Mazda's motor to find oil leaks and help out to who does the Clutch replacement.
