Clash, who voiced puppet Elmo for over 25 years, was named the Outstanding Performer in a Children's Series and shared the Outstanding Directing in a Children's Series title on Friday night (14Jun13).
He was also named among the executive co-producers of Sesame Street, which picked up honours for Outstanding Pre-School Children's Series.
The triple win is good news for Clash, who became the target of multiple lawsuits linking him to alleged sexual abuse.
It was also a big night for comedienne Ellen DeGeneres' talk show, which picked up six trophies, including Outstanding Special Class Writing, Outstanding New Approaches - Enhancement to a Daytime Program/Series and Outstanding Directing in a Talk Show/Morning Program.
Meanwhile, The Bold and the Beautiful won the battle of the daytime soaps with a handful of awards, including Outstanding Achievement in Hairstyling for a Drama Series and Outstanding Achievement in Music Direction and Composition for a Drama Series.
Former Doctor Who star David Tennant was also a winner - he was named Outstanding Performer in an Animated Program for his part in Cartoon Network series Star Wars: The Clone Wars.
The Daytime Emmys will take place on Sunday (16Jun13).
