Quoted from bluespin:
As soon as I derust the legs, wax the playfield and remove the beautiful nicotine patina I will!
Every body has their way of doing things. For removing nicotine that feels like it is a permanent part of the pin, I used Zip Industrial Purple. But there is trick for best results. Get a sprayer, if you want. Take the play field from the cab. If you are going to clean the right side of the cab, lay it on its left side. Either spray some Zip on and let it sit for a few minutes or soak a wash cloth and let the Zep sit for a little bit. After it sits for maybe 30 seconds the nicotine will wipe right off. Maybe it needs to sit for 60 seconds. But don't leave it on too long and get the cab soaking wet.
You can opt to spray it on a vertical surface but it is more tricky because you wind up with tiger stripes.
You can buy it at Home Depot.
Be careful with this stuff. It is caustic to your hands and lungs. Were gloves ! and a mask! If you don't have mask then hold your breath. It does not give off any fumes so using it inside is OK.
Use it at full strength.
Wax trick: I use cotton balls. They allow you to apply a thin coat of carnauba. It is easier to control and keep the wax off of your posts. Or just use your bare hands. Throw the sponge applicator away.
