Rob - Be sure to let us know how this worked out. We have 'before' pics will be good to see 'after'.

I know, I know, you always do this but I am really interested in your results as I have a number of similar issues with this same sort of residual adhesive.

 

Martha Stewart says: " MAYO it will remove the stickum on duct tape, and everything else."

 

Active ingredient is vegetable oil.

 

I bought my Boxster and whoever owned it before me had stuck some adhesive pad to the dash – very unfortunate.

obviously I did not want to damage the dash because it's perfect except for this adhesive issue. I first tried goo gone with a Q-tip that did absolutely nothing.

here is the method I used to successfully remove adhesive from the dash with no marks and leaving the dash exactly as it came from the factory

Heat the adhesive with a heat gun on low, you should see the adhesive turn white. Be careful to not get the dash too hot.

Next, spray a small amount of WD-40 on a microfiber cloth and gently rub the adhesive to start removing it. No need to use a lot of pressure, let the WD-40 do the work

In my case, it took 4 separate times with the heat gun and rubbing with WD-40 to remove all the adhesive. Once the adhesive has been removed mist the area with clean water and lightly scrub with a magic eraser.

This method completely removed the adhesive and left my dash perfect.

 

I've used citrus oil, which contains d-limonene, and which is probably a principal ingredient in most citrus cleaners, such as goo gone. I've also found neat citrus oil to be a brilliant cleaner/degreaser on parts, to get gunk off without using more aggressive/nasty solvents.
