another question about parts-washer solvent

[Scott Alexander <salex@devvax.Jpl.Nasa.Gov>]

Lee's question reminds me of a question I had this weekend.  The can
of parts cleaner that I bought 6 months ago has gotten to the point
where it's pretty disgusting.  What's the safe, correct means of
disposing of this stuff?

Thanks
