Castrol super clean?

[rbss]

I have a car that needs a light engine bay cleaning. I have a bunch of castrol super clean I need to use so im going to use it 8 to 1 in the engine bay. Will this be ok or should I use something that is better/safer?

i have used it before. just dilute it and you should be fine.

i used it pure, it cleans well but its wayyy to powerfull. my friend's aluminium rad came dull after

Has anyone tried this on tires at 4 or 5 to 1?
