How much isopropanol is effective but safe for viny?

Just saw your post- 

Search the forums for the formula, I remember seeing and using it in the past. 

The formula spells out the specific alcohol to use and suggests adding a few drops of ‘drying agent’ used in automatic dishwashers. 

Sorry I can’t remember the specifics.

100% effective, 100% safe.  Vinyl records can be submerged for decades in 100% concentration and remain like new. Plasticizers don’t leach in alcohol. Alcohol has the same PH as water. Alcohol has virtually ZERO impact on vinyl records. This has been a non issue for over 100 years. There are thousands of articles and real lab studies published online. 

I've used a 50/50 mixture of distilled water and cheap vodka for years with great results.
