Default Will Deoxit on a circuit board cause problems?

Main ingredient in common Deoxit is gasoline. Well, Coleman Fuel, well
Naphtha. It evaporates slower than some other solvents. The 5% oily
solution remains for some time. Flammable but not conductive.

Reverse engineering Deoxit is problematic because the formula has
changed over the years (starting with Cramoline) and because there are
multiple mutations sold under the Deoxit name. There's now a Deoxit
grease. Even so, I can assure you that gasoline is not used (it
evaporates and you would smell it).

The spray type is mostly "mineral spirits" or "naphtha". The "active
ingredient" is some kind of acidic oxide remover, such as oleic acid
(because it is food safe):

"Formulation: 5% DeoxIT® (active ingredient), 75% odorless
mineral spirits (carrier solvent), 20% propellant
Formulation contains petroleum naphtha (odorless mineral spirits)
solvent, and is briefly flammable (until solvent evaporates within
2-3 minutes). It's slower to evaporate, providing flushing action
to remove surfaces dirt, grease and other contaminants. Is ideal
for connectors and components removed from equipment or those
that are easily accessible. It is safe on plastics. When in doubt,
always test for compatibility, especially vintage equipment with
aging ABS plastic(s)."

Note the $150 for 7.4ml price tag for Deoxit Gold Pro GX3.

Ummm... right.
