[DML] Door lock lubricant suggestions wanted

["ctdmc83" <nmastrocinque@xxxxxxxxxxxx>]

[Subject line changed by moderator for clarity.]

This begs a question:  My door locks are getting "hard" (as if 
molasses rather than light oil or graphite was used to lubricate 
them).  What's the best recommendation for cleaning/lubricating that 
does NOT involve any disassembly?  WD-40?  Silicone?  Graphite?
I'd appreciate your thoughts on this.  I'm always a little concerned 
if the lock assembly might contain any small plastic parts that could 
be affected adversly by some solvent or lubricant.
