Actor Eugene Roche was the dishwasher man in the 1970's Colgate-Palmolive Ajax for dishes and as he would say "Squeaky Clean" dishes.
This was probably Roche's most famous role even though he was well known on Broadway and many roles in movies. In TV he appeared in Night Court as Christine Sullivan's father as well as other shows like Webster and Perfect Strangers.
Sadly Roche passed on July 28, 2004 of a heart attack. He was 75.
