Steering wheel cleaning

I have an Elf, still with the original steering wheel. Obviously, over the years it has picked up a fair bit of
grime. It isn't damaged, so I'm not looking to restore but would like to clean and polish it. Anyone done
this? If so what products did you use? I have cleaned up old bakelite phones and polished them with cooking
oil. However, on a steering wheel this is not going to work - a bit slippery.

i've used thinners before with good results - try a little underneath where it won't show first just to sheck there's no reaction

Cheers, will give it a go, I have a big tin in the garage
