Mineral spirits ( AKA Stoddard Solvent, paint thinner-if labeled mineral 
spirits) is the usual cleaner.  Gasoline is messy and way too explosive) 

The gears will usually have a dark color to non wearing areas.  The gears 
don't need to be shiny to work,  some gear lubes will leave a dark coloring 
to metal.

As someone else stated, ring and pinion gears can be mixed but will be noisy. 
 This is because after the gears are cut, they are mounted on a machine that 
runs the gears then lapping compound is applied. This takes off the high 
spots and matches the surfaces of the ring and pinion.

EP (Extreme Pressure) gear lube functions by leaving a solid coating of 
sulfur ( or other additive) on the wearing portions of the gear.  This solid 
film is what lubricates the gears.
