anhydrous is what you’re looking for in an clean alcohol, 99.9, however it takes time to evaporate, generally use for scrubbing purposes but probably have to use it carefully in this application

To try and prevent this happening in the middle of nowhere. i.e. I was at an event over the weekend and all i had with me was my camera, no bag. Kept getting the warning about the connects and all i could do was try and correct this problem with a cloth that i had with me. Otherwise i was sol.

Ouch.

No, no no. The pencil eraser solution dates back to the days of vacuum tubes. We need to stop that right now! Step away form the contacts, put your hands on your head.

Try the Ispropanol solution first (90% or higher) available at Grocery and Pharmacy stores all over.
IF that does NOT solve the problem - - yes - - LIGHT abrasion with a Pink Pearl would be next.
I recently FIXED a problem with my Canon 920 printhead using the eraser method.
Printhead replacement would have cost almost as much as a new printer - which Canon no longer makes.
Just NOTHING to lose - - and Everything to Gain.
Erasers (3-pack) $1.59: Printhead $89.95. Do the Math.

Any alcohol will have varying amounts of water, unless it 200 proof (medicinal). B&H sells electronic contact cleaner as a spray or in pre moistened pads....Pads are a fiber type of cloth to minimize any fibers falling off....make sure to clean contacts on lens barrel as well

99.9% Isopropyl Alcohol is available. Do not use rubbing alcohol it is only 70% alcohol and 30% water.

91% Isopropanol is also easily available - and MUCH cheaper than reagent grade 99.9%.
The 91% only has 9% H2O - easily evaporated with a hair dryer.

Rubbing alcohol is usually not 100% alcohol. They vary from 70% to 90% or so. I wonder what the other 10 or 30% is. If it's water it may not be very good for the contact.

It is likely water. It is very difficult to distill alcohol to get a cut without water. Just use it and allow it to air dry in a clean place. If it were me, I'd clean the contacts and let it dry under a very clean cotton cover - quality handkerchief or pillow case

As an audio recording engineer (on-location, classical music) for over 30 years, I can recommend CAIG Laboratories DeoxIT as an electrical contact cleaner. This is used on contacts for microphones--inputs and outputs--line level connections, switches, anything electronic.
Spray on to a Q-tip and clean gently; let dry.

This product is much better than alcohol and leaves no residue.

Hope this is helpful!

Yes, but blowing hot air from a dusty blower into a digital camera body is about as crazy as it gets. Don’t do that!

Use a Giotto Rocket bulb blower instead, blowing gently across and away from the interior of the body.

I definitely would not use a hair dryer!
I'd dry the contacts with another Q-tip if I thought they remained wet.
(They don't get soaked to begin with.)

wouldn't be prudent regarding the camera body. Might be OK for the lens side.
Q-Tips can leave tiny fibers behind as well. Using any kind of an abrasive on contacts could leave particulates behind - - so probably not a good idea anywhere around an open camera.

Yes, Q-tips can leave fibers, one simply has to be careful. I've never had a problem. Just don't be too vigorous in using them. No need to "scrub".
