Actually, cleaning is probably just removing oils (oil from people's
fingers, and oils from manufacturing). I have noticed this fact than freshly
cleaned LEGO holds tighter also, and suspect oil as the cause. I do know
that new LEGO does have some kind of chemical on it. When sorting brand new
LEGO, my hands start to itch. I have not had this itching problem when
sorting used LEGO that has been washed (though my hands have definitely felt
yucky after running them through used LEGO).
