You can experience virtually no surface noise while listening to vinyl. I have many LPs that are silent. They are clean and I keep them that way. Not by cleaning over and over but by handling them and storing them correctly. This yields good results. Cleaning LPs that have surface noise does improve noise as stated above. However you will not be able to remove scratches. If you have a favorite selection with scratches you can most likely get another copy on E Bay or new if its been re-released.
On the other hand, I have many CDs that are unlistenable due to compression and/or hiss. Obtaining, cleaning, and taking care of your LPs will give you enjoyable results.
