James,

I recommend at least either acetone or 90% + isopopyl alcohol to remove any
leftovers, and then wipe that dry.  I think Comet leaves a residue behind,
you might not have wiped it dry evenly between the 2 tests.  The last time I
used Comet on the sink, it leaves a very shiny and 'slippery' finish, it's
like a wax effect.
