engineered stone etched on sink in bathrooms

last year

I have white e-stone in all 3 bathrooms at the sinks that have etched markings. It is inconsistent throughout. I am sure it’s from cosmetics, face soaps, and/or liquid medications. I tried Lustro Italiano etch remover and I can still see the markings. I didn't work. Can a professional buff it out?
What type of professional?
Does anybody have any other recommendations?
