Yes, really great article -- thank you. Did a search on Goo Gone and found this from the article's author:
Goo-Gone lists its major ingredients as petroleum distillates (2.2) and d-Limonene (2.26). Therefore, the dielectric constant for Goo-Gone is 2.26, making it non-polar.
However, just because a solvent is non-polar isn’t the only consideration. Goo-gone and all citrus solvent turn into a thick pitch-like material as they age. I have heard many horror stories about people using Goo-gone to clean their track later to regret it because the residue gums things up badly.
No more Goo gone for me. There still is the question of which ones are okay for plastic wheels. And what to clean traction tires with?
