How should I clean my spark plug wires?

[cb7ftw]

Want to hear your tips for cleaning spark plug wires. Would like to know what you use, not what your heard you should use. Seen people say simple green. Others wd-40. Then people say don’t use wd-40 it will melt your wires. I have used sylicon spray before. Seems to work ok.

Silicon spray is probably the least harmful.

Why do the plug wires need cleaning? Seems like that is a bigger issue to me. If they are getting sprayed with oil then the oil leak is more important to fix.
Otherwise a cloth dampened with mineral spirits or rubbing alcohol to get stuck on grime off and a dry cloth to wipe off wet oil. You have to let the coating soak in something for it to be affected, I’d say whatever you are cleaning off them is probably worse than what you use to do it.

If you mean the connections I do not know about cleaning them inside the hoods on the wires, but I do use WD-40 (Water Displacement-40th Attempt) on all electric connections under the hood.

So your saying you have used mineral spirits to clean your spark plug wires?
