Hey guys,
Thanks for all the great suggestions....just as a followup for anyone interested, I used the two things I had close to hand---I soaked one in Era laundry detergent/water mixture, and soaked one in gasoline. Both suggestions worked beautuful! I don't know what they put in laundry soap, but must be more powerful than Napa parts cleaner. I had previously soaked them two weeks in Napa parts cleaner and that didn't take care of it entirely, only for a couple days in gas and Era. Thanks again...
