I run copper champion by the way in my 97 grand 4.0. If you do clean your plugs how do you do it ?
I know just buy new ones their cheap as I did but the old ones looked great so I just sprayed them with carb. cleaner and reinstalled with new crush washers.
I've done it on my 4.0 and others over the years. There is a little tool made for it that is essentially a thin file, but not as aggressive as a real file. Kind of like one of those metal fingernail files. All my tools were stolen several years ago and the ancient hand-me-down spark plug tool I had was lost. I use fine sandpaper / emery cloth. All you're worried about is the end of the electrode and the area on the ground bar across from it. Well, unless you have oil & gunk buildup or carbon bridging.
Lol HL and nobody here to clean my plugs for me either!
I used to clean my spark plugs just using some fine emery cloth on the electrodes then spraying them down with carb cleaner.
For quite a while I was using my bench grinder with med wire wheel for cleaning the electrodes. But this darkened the ceramic insulator. I heard this could be a fine metal coating, bad idea, so quit using this method.
I'm at the point if pulling the plugs they're getting replaced. Even though I have a set of new copper Champions I bought a set of NGK copper plugs which look like better quality. Hope to install them soon on my 96 4.0.
BTW, I use a non-seize stick on the plug threads and a real thin coating of dielectric grease on the outside of the ceramic insulator when installing new plugs.

Agreed. It's not the 1970s any more. If your spark plugs actually get crusty enough to need cleaning you have much bigger problems with the engine itself.
I'm pretty sure people only cleaned spark plugs due to leaded fuels. That's not a thing now so there's no need. If the engine is putting actual build up on the plugs then there's another issue that needs fixed.
