Hello Ibog1,
This is an awful lot of alcohol to be adding to a mix.
As I understand it, other than being wet, your DIY is really not that effective a cleaner.
There was a fairly good, but very lengthy article here some time back, can be found in the archives, called "A very lengthy primer of record cleaning fluids", written by Justin_Time, that might give some insight, and ideas what a cleaner, or I should say way a "good cleaner" should do, and not do.
When one gets right down to it, even the most costly, state of the art cleaners that are made today are figured on a "per record basis", they too really don't come out to costing much more.
The problems I see with many DIY formulas, is off the shelf products, which are not optimum for use on records, and the entailing difficulties for an end user acquiring very high quality, and high purity ingredients.
Although I haven't tried every single commercially available cleaning product on the market today, I would venture a very good guess that "all" of them (The best known brands) do do a very good job as far as cleaning, as far as leaving little, to no sonic signature, or residues, and last but not least, causing little-no harm to precious vinyl.
Yes, there's no denying that DIY can, and will be less expensive, but you'll find for various reasons, many, and many here in this forum have perhaps gone that route, have discovered-recognized the certain shortcomings, and for the quality of sound they wish to achieve-attain, many of the DIY cleaners they find, and have tried, fell considerably short.
You would find that once they "hit" on thier product of choice, they would never consider going back to DIY.
I'm no chemist, but have been in the hobby long enough, to prefer the use of highly trusted, and reputeable cleaning products.
And, it was many of the highly knowledgable members here in this forum who have helped me have a better understanding of vinyl, and analog playback. Mark
