I admit that I never clean discs unless they won’t track. With CDs I use isopropyl alcohol and wipe with the tissue that opticians sell for Frac lenses and that has always worked. Although I own over a hundred SACDs I don’t remember having to clean one until I had loaned a recording of Mahler/5 to a fellow Audiophile who wanted to explore both the Composer and SACDs (Zander/Philharmonia on Telarc)). When he returned it he said that he had cleaned it with some special highly touted commercial cleaner that was expensive and he only reserved for his finest discs.
The disc was unplayable, in 3 different players, on either the SACD or the CD layer. After letting it sit for a few days, with no improvement, I tried isopropyl and it was fine.
