Ed, I've asked for the "recipe", Dave just gave me a wink and some vague hints as to what makes up the mildly acidic, slippery liquid. He sells it as a concentrate, and a little bit of it goes a LONG way. If Shilo's selling the media, they would almost certainly have the cleaning solution / concentrate, too,....No ?
I just phoned him, the last time I needed some.
