I found this "Contractors' Solvent" at the local ACE -- works so well at removing that grease around the hot area of tube amplifiers that it will take off lettering if you allow it to work for too long.

Well, Brake Kleener will take the lettering off right quick.

Try Gez-off. It usually won't take lettering off but removes almost anything else including nicotine. https://www.spraynine.com/product/spray-nine-grez-off-heavy-duty-degreaser-5/
