What is the best/easiest way to clean areas affected by the acid flux? I have used warm soapy water with a little baking soda but would love an aerosol type of cleaner that could do the trick.

Use aerosol can of contact cleaner available from a electrical parts store. This is also a very good comutator cleaner.  

Lately I have been using aerosol brake cleaner with equally good results.

​Both of those products leave no residue.

Those cleaners will neutralize the acid? I have to admit I didn't realize that.

 

I've always just washed the area with a little dish soap and an old toothbrush.

I use dish soap and warm water with a wire brush for most clean ups, but after repairs or small touch ups on completed cars, I have been having good results with 409 spray cleaner. It works really well for clean up after adding earring backs as lead wire retainers and after soldering retainers fro front wheels. Also after installing rear axle bearings or bushings.

I use Ajax or Comet and a Scotch Brite pad. If you want an aerosol product try some battery terminal cleaner from the auto parts store

Something similar like this might work. http://www.salvin.co...SPRAY-LUBE.html

We did have some aerosol stuff but can't remember the brand.

When I build my Retro chassis they get many trips to the sink for a good cleaning with an SOS pad. This removes and residue and also polishes the metal. I then use a fine metal polish for the final touch. PS--do not use Brillo as it is too coarse.

Was in the electronics industry for a minute. There are many cleaners that the PCB manufacturers use to clean flux.

Most use a 2 step process. First at assembly an aerosol alcohol based product is used, then secondly a water and cleaner bath.

If it's a new build, I use the trusty old toothbrush and Comet cleanser. For field repairs, I'll flush the area with lighter fluid, and wipe with a rag (this step depends on the amount of time available).

After I built my first Eurosport chassis recently with a lot of rust after, even after cleaning up, I realised that the 2-3 hours it took me to build the chassis was enough for some discolouration. So I figured next time I will clean up every solder joint right-away. Fuelite is very good at dissolving the flux, using toothbrush also. What could also help is adding a bit of bicarbonate of soda to the fuelite to neutralise the acid, saves you having to rinse in water every time.
Then of course still rinse with water once completed

Acetone with Q-tip removes quick and easy.

I keep some baking soda in a old tire tube and a toothbrush for use at the track.You just sprinkle a little on and hit it with a wet brush and hose it off with some CRC electrical cleaner or Brakleen.The bonus of baking soda is it accelerates and  fill in things with CA/super glue. At home I usually just dunk it in some warm soapy water or run it under the tap,motor and all and then hose it with cleaner and blow dry.

Corrosion-X also works great.
