follow-up
Finished the job. After a extensive R & D program trying several cleaning compounds and methods (409, Pinesol, Alcohol (externally applied not internal till the job was done), paint thinner, Simple Green,etc) I found the easiest and most effective was a cleanser with clorine and a Scoth Brite scouring pad. Worked fairly easy and then I followed up with wax. Looks great.Happy cleaning!
