I've 10,000+ LPs - but no RCM. Maybe I should have - but..~5mins to
clean each LP....??
For just 50 LPs there's An Alternative.
Ignoring the prospect that your Iso-Alcohol formulations haven't led
to permanent crackles - and assuming that the 70/80s material is
'Pop' then you could play them WET - the LP side could be re-wetted
when transcribing tracks if the surface dried out.
Although I'd not do the above, it's a safe bet that you'll
potentially get a silent backgound - even more so if you cleaned the
LP beforehand with a water/detergent solution -"Morning Fresh"
'Wildflower Melody' (Mauve..) is pretty OK - no citric acid, I
suspect..rinse
under running lukewarm water (if you're adept you can get an
immediately dry surface using that method..).
Wet-playing is well known to have some advantages - and, for your
application, might well be the answer.

Thanks for the suggestion! I've just tried that on one of the
really poor LPs (one that I'm not bothered about, I hasten to add)
and it made an amazing difference - other than the occasional
crackle, the background noise was near-absent, compared to previous
attempts on it with cleaning but allowing it to dry. I assume that I
should ideally use distilled water for wet-playing?

Doesn't the sound alter, I would have thought it would have 'dampened' the
higher frequencies?
Perhaps if you did it with a touch of detergent and distilled (not dionised)
watee then thoughly rinsed them you'd clean them quite effectively?
