Elizabeth is right. But many online formulas call for only 1 or 2 parts isopropanol(90%) added to distilled water. I found these recipes interesting...

is it safe to clean records with isopropanol ?
I've been thinking of making some home-brew record cleaner. Most of the online recipes use 20-25 % (or more) isopropanol.But some think this is not good for modern vinyl because it leaches out plastic stabilizers in the vinyl.Others think the ill-effects are due to contaminants in the isopropanol.I can get access to lab grade ISP so was wondering if you had any advice before I make the plunge. I have about 300 lps that I want to clean.
