I remember an old TR7A that I picked up from a friend. He threw the dead
roaches and their droppings in for free.
First of all, I gave each of the boards a bath in soapy water. After rinsing
them in clean water, I gave them another soaking in Isopropyl alcohol. It
took 13 gallons of alcohol to clean that radio. There were even roach husks
enmeshed in the PTO gears. I had to complete dismantle that PTO.
After all of that effort, there were still some stains from all of the
droppings that had embedded themselves in the wiring insulation. Too bad
they didn't use teflon insulated wire. When I explained the history of the
radio to the buyer, he couldn't believe that it was ever in that condition.
Good thing that it is just smoke and nicotine, in your case!

I find the shower works well, but try and keep the coils dry. I spray
with PH balanced shampoo, let it soak and hot shower it out, a lot of
"it" comes out.
