Not unlike most of what Fremer says, IMHO, he doesn't know of what he speaks regarding record cleaning fluids. The RRL fluids DO disperse into the grooves, they just don't stay there. The idea is that they enter to the grooves, do their business, then bead on the SURFACE, not IN the grooves, with the gunk suspended in liquid to be vacuumed away.
I have used the AIVS stuff and found that it seriously compromises the high end. Only when thoroughly rinsed away with Super Vinyl Wash (AND NO EASY JOB, THAT) does this tell tale signature disappear. Way too much work. In the event of a really filthy LP, I generally look for another copy. But, if that is not possible, I'd go with the Vinyl-Zyme instead, everytime - it being MUCH easier to remove than the AIVS.
