Wax and Grease remover... PPG. This is the pre paint prep and is safe for all finishes, non-abrasive. My daughter when around 2 years old took a Sharpie and "signed" her dresser... an old maple dresser that I had refinished. My wife was horrified... I went out to the garage, grabbed my Wax and Grease remover and with a little elbow grease it was gone... 14 years later the dresser still looks great. You will need to go to an automotive paint shop for this. Works great for also removing sticker residue, gum, etc. Probably some other things that will work but I know this does and works great for other challenges around the house... plus it is great for those spray paint projects.
