Best cleaning solution to put in a ultrasonic?

So I am a freak about getting the lowest surface noise possible on vinyl, and I have been using dawn dish soap + jet dry in my ultrasonic, but I heard that some kind of alcohol solution works better. What do you guys think, what is the best cleaning solution to put in my ultrasonic to achieve the least noise possible?

Btw I play 70s disco vinyl and I have a Shure SC35C stylus if that’s important .
