I'm sorry I just don't buy the sales pitch about jack sockets. They either work or they don't. If you want to pay over the odds that is your decision.

In 24 years I've only ever had to change one jacksocket on a guitar. A mono to a stereo.
Greatly overhyped problem in my experience.

Am i missing something here? Is WD 40 somehow different in say the states to Europe ? It wont do any harm at all and when someone wanders to the garage or wherever people keep those things and sees some WD 40 but maybe no contact cleaner then by all means give it a squirt,

Contact cleaner does what it says on the tin ie cleans contacts, such as oxidised surfaces etc, a quick squirt if you have any often cures these things.

Id already suggested the removal method if this didnt work.

It doesn't do your guitars wood, pots or switch any favours. it tends to leave a film over things too. It never fully evaporates.

I like you have used it in the past and not suffered adverse effects. I do however think that was more luck than judgment on my part.

If your looking to clean small parts you cant get better than a nail polishing file, if you ask me. I don't really buy into the contact cleaner stuff too. It's got to be somewhat corrosive to clean metal. If thats the case, I'd rather be governing whats doing the shifting of muck.

Then why are we responding to a thread asking for help solving a probable jack problem? Not the first time I have seen this subject discussed here or in other forums.

I find it truly amazing that people will spend hundreds of dollars swapping pickups in search of that elusive "tone" but poo-poo a better solution for a problem that can stop that "tone" dead in its tracks. Oh, well. I am happy I have ordered the beter quality jack. I'll shut up now.

I'd rather have the better jack and not need it than need it and not have it.

I suppose I know I have a commercial Switchcraft jack the same way you know you have the same jack in all of your guitars: I looked.

I would just replace it.

The switchcraft military jack has a third less contact resistance and will live through twice as many insertions (compared to the consumer version).

The only reason to clean is if you want to keep it original.
I wouldn't use anything overly abrasive.
Some compound cleaner or 3000 grit sand paper to buff the contact points a little and then rinse it off well in some alcohol.

Of course you don't get any cleaner on the finish or wood.

Don't shut up mate ever. Your thinking along the right lines, all I'd ask you to do is consider further along the lead from your jack socket
(thats about as much as a hint as I'm giving).

You'll do whatever makes you happy as is your right. What can be stopped one end, can also be stopped the other. (dammit theres another hint).

I'm clueless.

All I can do is guess that you are referring to all the other connections in the path between the guitar and amp. Well, I use Planet Waves cables. The jacks in the Blues Deluxe Reissue amp are improved versions of the ones in the original Blues Deluxe. I am gradually replacing the cables between my foot pedals with better cables. If I can replace the jacks in the pedals, I may do that too.

Oh, my new jacks came today. They are truly a work of art!

By the way, I don't gig. I'm just an engineer who happens to enjoy playing the guitar.

and made some light scratching movement contact
