How much isopropanol is effective but safe for viny?


I make my own cleaning fluid using isopropanol and distilled water but am aware that some think IPA is not good for vinyl. Since  the contact time is quite limited I think that it is probably OK to use a small amount as a solvent for greasy contaminants. What do you thing know is a safe level? 25  percent, 10 per Cent , or some other level??

@slaw My post makes perfect sense.  Isopropanol should NOT be used on records.  Period.  It does not clean off the substances that need to be removed from the grooves of vinyl records and removes the plasticizers that need to remain on the records.
@bpoletti

So you are saying it removes plasticizers that need to remain on records is the best thing?

I think you need to re-word your post my friend.
Yes, the plasticizers are needed to preserve the vinyl.  Sorry for the confusion.
