Technical What's the Best Way to Clean Spark Plug Wires?

Lacquer thinner

 

Had to go check to see if my memory is slipping.
Used Taylor wires cause, well you know.
Still works.



Note: new Taylor 8mm kit so only rubbed a little off.

 

Way back when I had "pretty" plug wires I worked in the gas station. They had the old parts cleaner tank, I would get a shop rag wet with the solvent and wipe the wires clean. It took off all the lettering on the wires, but they were sure easy to clean. I started fixing oil leaks (and any other fluid leaks) before they caused issues, that helped a bunch.

Then I quit making my motor "pretty" I went with the all black plug wires (function over form). I was quick to notice that when I didn't need everything pretty, I had a lot less issues with dirty plug wires. When the plug wires got "bad" they got replaced.

I don't open my hood to show off my motor very often any more. Nothing fancy to see under there, not many want to see an ordinary, factory installed looking motor anyway.

 

That's the same for a lot of us .... especially the last 10 years ...
