mijostynDenatured alcohol is bad news on vinyl but Isopropyl is fine.
The matter of whether alcohol solvents are safe on LPs has been the subject of such debate for so long that I don’t think you can authoritatively state that "Isopropyl is fine." I’d be interested in any evidence you have to support the claim, though.
The question I ask is: What is the need for such a solvent? I use nothing but an ultrasonic RC machine and pure distilled water to clean records, and haven’t yet found any contamination that they can’t remove. And yes, I buy the occasional used LP.
If you use a dust cover, a grounded sweep arm and never smoke or cook around open records you will never have a problem.
I don’t care for grounded sweep arms - though I have used one in the past - but even they won’t eliminate dust from LPs.
The issue of whether to use a turntable dustcover while playing records is also subject to debate. In particular, I have seen a dustcover’s static charge completely lift a pickup arm off of the record! That makes me wonder if VTF can be affected even in the absence of such an extreme situation.
The only way a clean LP can remain completely dust-free is to keep it in a clean sleeve within its jacket. Once it’s taken out to be played, some amount of accumulated dust is inevitable.
