Safest way to remove glue residue from dash

[IM-32-FK]

Finally after years of owning the car, I removed the HUD display the previous owner installed. But there’s a lot of glue residue underneath. 
 

There are hundreds of products that can probably remove it like ph neutral spray cleaner, carby cleaner, contact cleaner, brake cleaner, petrol, metho, turps, bug and tar remover, goo gone etc but I don’t want to try anything because of the fear I might discolour the dash. 
 

So what do you recommend to use to remove glue and glue residue from dash without damaging it?

Try goo gone which is a citrus oil.

Could try wd40 to remove the glue followed by all purpose cleaner remove any oily residue

I find eucalyptus oil good for glue residue 

Plus it clears the sinuses and I think it leaves a nice smell.....eucalyptus.....leaves.......nice
