Sounds like you got everything under control and on it's way back to normal. How about taking the suspicious areas or parts you think got your magic cleaner stuff on and douching them with greased lightning or equivelant strong degreaser, then washing with clean water then let sit in sun or oven at 100 degrees for long enough to dry? A mentor of mine, Ed Callahan of Ed's TV in St. Petersburg, Fla would sometimes get a chassis with heavy cig smoke and or roach poop like a 19" Motorola Quasar from like '73 that had such gunk in it and many roaches. He sprayed it all with degreaser, hosed it down and let the sun dry it. It lasted many years after that. He would not normally get involved in things so disgusting but the owner bought the set from him new as he was a Quasar dealer and he cared about the interests of his friends even though they were clearly nuts. This set 's owners owned much property and were quite wealthy yet extremely cheap til the bitter end when thier estranged daughter inherited it all. Seems like that behavior happens alot. So, anyway, that TV sat in the back room of thier pharmacy of thier little nighborhood store on a high shelf. The store was at the corner of 58th St and I think 46th Ave in Kenneth City which is in St Pete. Just checked google map. It's on 54th Ave and now called el toro negro(not surprised)The Minella's would sit in that shop all day watchin that set til they died. It had been opened in the early "50's and lasted into the '80's when the daughter sold it for a huge bundle. Now it is has that funny smell ethnic stores here in Fla often have like they dont change the mop bucket water. Ooops, am I rambing again? I need some meds
