"Former chemist here. The real secret to life is that dish soap works on damn near everything. Even when I was trying to clean industrial parts, I found that nothing works as well as dish soap. Oily shop rags? Dish soap. Shop floor? Dish soap. Bench covered with machine oil? Dish soap. You can even use dish soap to wash your carpet. If dish soap doesn't work, move to rubbing alcohol. If alcohol doesn't work, try WD40 (then remove WD40 residue using alcohol). If absolutely nothing else works, try acetone as a last resort. Acetone destroys plastic though.Another one to try is laundry soap. Laundry soap is extremely harsh compared to dish soap. It will clean damn near anything but it tends to leave residue, and it will dry the hell out of your hands because it strips all of the oil off your skin."
