Doug is correct about scrubbing. Not only with RRL but any of the good cleaning solutions. All of these products contain a small amount of surfactant which stands for SURFace ACTing AgENT. I have no idea why "they" used an A instead of an E; chemists are strange folks.
Surfactants have many applications, industrial and otherwise. They are used in shampoos, cosmetics, hand cleaners, etc. Their purpose is to reduce surface tension of the solution in which they are contained.
For grins and giggles, put a few drops of water on a non-permeable surface such as your kitchen countertop. Now take your favorite record cleaning fluid and add a single drop. Watch how the water spreads. The surfactant has lowered the surface tension or friction of the water in regards to the countertop.
In a record cleaning liquid the surfactant lowers the friction of the solution in regards to the record groove and enables it to penetrate quite easily making the amount of scrubbing minimal and in many cases unnecessary.
Thanks for listening.
