Crem1, I took out a record which I bought several years ago for $8.00 by Clifton Chenier "King of the Bayous". This vinyl had so many marks on both sides, it was impossible to even see the scratches, but when both sides were played, the noise level of crackling was appalling. I decided to clean side A only with steam followed by a water rinse whilst side B had the steam plus L'Art du Son + a water rise all performed on the Hannl machine sold by TW Acustic. Both sides looked the same after the clean with surface scratches now clearly visible. the sound however was clear and crisp on BOTH sides with only the gap between tracks displaying a slight surface noise. To me this indicates that steam cleaning plus a rinse is all that may be required to fully clean vinyl? This could potentially save each and every audiophile hundreds of dollars over the forthcoming years? it would be good if someone had access to an electron microscope to confirm on a molecular level, the state of the grooves after steam cleaning and fluid cleaning? Until then, I think my days of purchasing cleaning fluids may be over?
