Long ago, I dove deep down into record cleaning solutions. I think there was some very compelling evidence that alcohol is a no-no on vinyl. It dries out the vinyl. There are some incredibly detailed long papers on the subject... one I think for or about the archival cleaning for the Smithsonian. To me, it is just worth it to buy VPI concentrate and make a gallon... and not worry about it.
I'm not sure even your dedicated audiophile will hear dried vinyl... I am not 73 and most of my albums (2,000) probably on average have only been played 10 times... except really classics that I loved, then maybe 25. None of this is really hard long termed use.
