A sweeping generalisation, and not necessarily accurate. Light curing conformal
coatings work very well in the appropriate circumstances (including pcb's which
have not been cleaned). The geometry of the assembly and application method are
two of the factors which determine whether a light curing coating will work for
you. Testing with the flux residue(s) is advised, as it is for any coating.
