I bought some Gunk and followed the instructions to clean my engine. It didn't very much. I ended up going over everything with Armor All Anyway which as always pulled through.

Thumbs up to Armor All
Thumbs down to Gunk

 

agree gunk sucks,never works for me

 

I have a friend that reccomended it or I would have gone with Black Magic or something...

 

i just use simple green on the motor... it cleaned all the mud off of mine.

 

x2 that gunk sucks...BTW where do you get Simple Green?

 

 

Anybody have any before and after shots of Simple Green?

 

I have always like Gunk but when I used it last I had an 1984 full zise K 10 Blazer. It did a great job cleaning. I will have to try it on my truck this week and see what it does?

I have an fuse/relay in my engine bay for my KC lights. If I was to spray Simple Green or some other cleaning product and then wash it off will there be any damage?

 

Gunk is really just effective on grease/oil -- I've never known it to do much for dirt.

 

the foam gunk is way better i have used them both and in one of tmy threads i show what my engine looks like
