For cleaning electrical contacts & shovelhead connectors, is there any household fluid that'll do the job?
You know, swab it on with Q-tips...

Use 91% or 99%, not anything less pure.

Isopropyl alcohol (IPA), as "ioerr" says.
The "household" versions are either rubbing alcohol or tape head cleaner.
For preventing future corrosion, mix a very small amount of thin oil (3 in 1 or sewing machine oil) in with it. That leaves a film on the metal surface that prevents corrosion and maintains a lower resistance.
You can also just use oil on a cloth or cotton bud, if you are careful to avoid any excess or it can be cleaned off easily.
That works well on such as jack plugs (like guitar cables & aux cables) where you can easily wipe them down afterwards so only a trace film remains.
Plug them in immediately so some transfers to the contacts in the sockets.
A lot of commercial contact cleaner sprays are basically solvent with trace of oil. The downside is the oil film stays sticky and can attract dust, if it's not in something that fully encloses it.

I use a Contact Cleaning Pen - looks like the little stain remover pens, with a felt wedge tip. This one has lasted quite a while - says RADIO SHACK on the tube. See what Google turns up for you.
