Thanks for the many suggestions.

I don’t want to take the valve cover anywhere to have it done due to the time involvement. Guess I’ll use some form of degreaser from a local auto parts store along with a large enough tank with lots of paper as a backing and then ball up the mess and put it in the trash..........and hope it doesn’t spontaneously explode before the trash removal comes....
