Cleaning nicotine staining

I’ve got my original blue dash pad from my car that is in nearly perfect condition. It’s been in storage since '78.
I really really don’t want to have to paint it.

There is some pretty nasty nicotine staining on it.
I’ve tried several household cleaners simple green, the purple stuff etc. and nothing seems to even touch the staining.

Is there anything out there that is good at cutting through nicotine without ruining the original vinyl?

Sounds like it’s trash, but I’ll take it off your hands,lol
Try Spray Nine, it’s good stuff

You can try the product I live by, it’s called Greased Lightning, if that won’t take it off, it’s there to stay, and it won’t hurt the vinyl. also great for a cleaner before a re-dye.

Try ammonia. That’s what we use in rental units that had smokers.

How about WD-40.
Works on about everything else.
Very good at removing tar.

Never thought about wd40. Kind of funny that nasa developed it as a de-icer and it has proven useful for so many other things. Greased Lightning and Mean Green are my standbys. If they don’t work it’s time for Awesome. That stuff will clean off just about anything.
