Triple deionized water for cleaning lps ?

Okay, I'll take my pure water "with a grain of salt"

John Tracy is quite correct. Purifying water to a desired level is relatively easy. Keeping it pure is impossible outside of a laboratory environment. Especially if you're buying it in on a commercial basis. Why waste your time and money?

Rel: I found the article you recommended to be particularly interesting and helpful. Kind thanks.

Opus88, you may want to ask Albert Porter about his experiences with record cleaning fluids. some of the solutions he has worked with lately are astonishingly effective in removing the subtlest particles of ancient schmutz. . . As you may have guessed. . . I am a bleedin' skeptic to start with , but the sonic results I heard at his place last month were not at all subtle.
