I prefer the Audio Intelligent products, they flow better, clean better and cover the record, where the RRL stuff always beaded up.
It seems that the old adage "you must empty your tea cup before it can be filled with the new" really worked for Paul Frumkin. Being a lawyer, he came on to this project with his teacup empty. I remember him really soaking up (pun intended) my advice on ultrapure water production. I'm about to receive some products he offered me back then. Now I have a used Record Doctor RCM and have all my remaining albums together in one place. From what he was explaining to me back then the combined action of the soap used and ultrapure water make an effective combination that does not have much surface tension, yet has adequate cleaning action.
