 Hardware store is fine for general rinsing but tends not to be optical quality when preparing a sample for imaging.  This is usually seen as streaks or small particles on the die.
-DudaDiesel sells acetone that is sufficiently pure to clean dies for imaging.
+DudaDiesel sells acetone that is sufficiently pure to clean dies for imaging (XXX: much better than hardware store but not clean enough.  Rinse with distilled water)

-Some problems during cleaning found traced to volatile residue.  Question: what does it take to get acetone with very low volatile residue for cleaning?  Alternatively, can I get another volatile compound, say IPA, that leaves less volatile residue?
