i am just starting a new project car right now.
i'm looking at the engine harness that is still present in the shell i'm working with
but its super dirty. there seems to be a caked in residue of some sort.
is there a proper way or best way to clean this gunk out?
i am afraid if i dont clean it, it might lead to problems later due to the fact that its so dirty. at the same time, i dont want to ruin it.. thanks

 

hose that sucker down,should be fine.ive sprayed about 40 of them down and they all worked.if your scared,put some duct tape around the plugs.

 

get some spray nine and a tooth brush. Clean a few inches at a time and then either spray it off with a hose or wipe it off with a rag.

 

thanks!

 

Simple green works well too.

 

use heavy duty cleaner.
i suggest brake cleaner cuz its pretty strong and just power wash the **** out of it

 

reloom its and be done with it
